Start NowThe Smackover Formation is an Upper Jurassic-age carbonate and evaporite geological formation deposited approximately 155 to 145 million years ago during a period when shallow tropical seas covered much of what is now the Gulf Coast region. Named after the town of Smackover, Arkansas in Union County, this formation has been one of the most significant petroleum-producing units in the Gulf Coast for nearly a century — and is now at the center of America's emerging domestic lithium industry.
The Smackover Formation extends across the Gulf Coast subsurface in a broad arc stretching from East Texas through south Arkansas, across north Louisiana, Mississippi, Alabama, and into the Florida panhandle. The formation was deposited along the margins of the ancestral Gulf of Mexico and is part of the larger Jurassic sedimentary sequence that underlies much of the Gulf Coastal Plain. In the core lithium-producing area of south Arkansas and northeast Texas, the Smackover lies at depths of 7,000 to 12,000+ feet below the surface.
Geologists divide the Smackover into three distinct members, each playing a critical role in the formation's petroleum and lithium systems:
Lithium in Arkansas Smackover brines alone
During the Late Jurassic period, the Gulf of Mexico was a young, restricted ocean basin that was slowly opening through rifting of the supercontinent Pangaea. Warm, shallow seas covered the continental margins, creating ideal conditions for carbonate deposition. Tidal flats, lagoons, and shallow marine shelf environments produced the oolitic and peloidal limestones that make up the Smackover reservoir. Periodic restriction of water circulation led to evaporation and the deposition of thick anhydrite and salt beds that now serve as seals and also contribute to the high-salinity brines that contain dissolved lithium.
The same geological processes that trapped petroleum in the Smackover also concentrated mineral-rich brines at depth. Over millions of years, formation waters interacted with the surrounding rocks, dissolving minerals including lithium, bromine, calcium, and other elements. These brines have been co-produced with oil and gas for decades, but only recently has the lithium content been recognized as a commercially significant resource.
The lower Smackover mudstones served as the primary source rock for oil and gas that migrated into the overlying oolitic reservoir. Total organic carbon values and thermal maturity indicate significant hydrocarbon generation capacity throughout the formation's extent.
The same porous and permeable oolitic grainstones that hold oil and gas also contain massive volumes of lithium-rich brine. These highly saline formation waters have been trapped at depth for over 100 million years, concentrating dissolved minerals to commercially significant levels.
The Buckner Anhydrite and upper dense limestone members provide an effective regional seal that has preserved both hydrocarbons and mineral-rich brines. This impermeable cap rock extends across the entire Smackover trend, ensuring that formation fluids remain trapped at reservoir depth.
Long before lithium became the headline story, the Smackover Formation was one of the most important oil and gas producing formations in the United States. The formation's production history stretches back nearly a century and has generated billions of dollars in petroleum wealth for mineral owners across the Gulf Coast states.
Oil was first discovered in the Smackover Formation in the 1920s in south Arkansas, near the town of Smackover in Union County. The discovery of the Smackover Oil Field triggered one of the great American oil booms, transforming small Arkansas communities into bustling petroleum centers virtually overnight. The towns of Smackover, El Dorado, and Norphlet became synonymous with the early Arkansas oil industry. At its peak in the 1920s, the Smackover field was one of the largest producing oil fields in the world.
A key deep test drilled in 1937 in Union County confirmed that the Jurassic-age Smackover limestone was the source of this prolific production, opening the door to systematic exploration of the formation across the entire Gulf Coast. Through the 1930s and 1940s, Smackover production expanded into East Texas around the Longview, Henderson, and Carthage areas, across north Louisiana's salt basin, and into Mississippi, where the formation contributed to the foundation of the state's early petroleum industry.
Discovery Phase: Smackover Oil Field discovered in Union County, AR. El Dorado boom. Early Gulf Coast exploration begins.
Expansion Phase: Production expands across TX, LA, MS, AL. Deeper drilling reveals new Smackover pay zones across the trend.
Mature Phase: Enhanced recovery methods including waterflood and gas injection extend productive lives of Smackover fields.
New Frontier: Lithium discovered in Smackover brines. Major companies invest billions in lithium extraction alongside continued oil and gas production.
South Arkansas: The original Smackover production area. Union County (El Dorado), Columbia County (Magnolia), and Lafayette County were among the earliest and most prolific producers. Many fields have been on continuous production for 80+ years.
East Texas: Smackover production in the Longview, Henderson, and Carthage areas of Harrison, Rusk, and Panola counties. Some of the deepest and most prolific Smackover wells in the trend.
North Louisiana: The North Louisiana Salt Basin contains significant Smackover production in Webster, Claiborne, and Lincoln parishes, with many fields producing from Smackover and deeper Jurassic reservoirs.
Mississippi: The Smackover formed the basis of Mississippi's early petroleum industry, with significant production in the southwestern part of the state and along the Mississippi Interior Salt Basin.
Alabama: The Upper Smackover Oil Trend in central Choctaw County ranks among the Gulf Coast's top trends, with individual wells averaging over 900,000 barrels of production from depths of 11,000-12,000 feet.
Bromine Production: In addition to oil and gas, Smackover brines have been commercially produced for bromine extraction for decades. LANXESS (formerly Great Lakes Chemical) operates one of the world's largest bromine facilities in El Dorado, AR, processing Smackover brine — the same infrastructure now being adapted for lithium extraction.
Despite nearly a century of production, the Smackover Formation still holds significant petroleum resources. A 2022 USGS assessment estimated undiscovered, technically recoverable mean continuous resources of 0.8 billion barrels of oil and 16 trillion cubic feet of gas remaining in the Smackover across the onshore Gulf Coast, plus an additional 143 million barrels of oil and 1,084 billion cubic feet of gas in conventional accumulations. Many mature Smackover fields continue producing through enhanced recovery operations including waterflood and gas injection programs. The formation remains an active drilling target for both conventional production and now, increasingly, for lithium-bearing brine.
The Smackover Formation has emerged as one of the most significant lithium brine deposits in North America, potentially rivaling the established lithium-producing regions of South America and Nevada. The same subsurface brines that have been co-produced alongside oil and gas operations for decades contain dissolved lithium at concentrations that are now commercially viable using modern extraction technology.
Smackover brines contain lithium at concentrations of 100 to 800+ ppm, with the highest reported concentration in North America — 806 mg/L — measured from Smackover Lithium's Pine Forest 1 well in East Texas. Average concentrations across the trend range from 150-400 ppm, well above commercial viability thresholds for modern DLE technology.
A landmark 2024 study by the U.S. Geological Survey using machine learning estimated between 5.1 and 19 million tons of lithium in Smackover Formation brines in southern Arkansas alone. This represents 35% to 136% of the entire current U.S. lithium resource estimate, making the Smackover potentially the largest lithium deposit in the United States.
The highest lithium concentrations are found in the south Arkansas and northeast Texas portions of the Smackover trend. Columbia, Union, Lafayette, and Calhoun counties in Arkansas and Cass and Marion counties in Texas represent the core lithium-prospective area where major companies are concentrating acquisition and development activity.
Lithium in the Smackover Formation is not found in hard rock like traditional lithium mines in Australia or pegmatite deposits. Instead, it is dissolved in formation water (brine) that fills the pore spaces of the oolitic limestone reservoir at depth. Over tens of millions of years, these highly saline waters interacted with the surrounding carbonate, evaporite, and clay minerals, leaching lithium and other elements from the rock matrix. The impermeable Buckner Anhydrite seal above the reservoir prevented these mineral-rich fluids from migrating, resulting in a massive, trapped lithium-bearing brine reservoir.
This brine is the same fluid that has been produced as a byproduct of oil and gas operations and as the feedstock for bromine extraction for decades. The lithium was always there — it simply was not economically viable to extract until the development of Direct Lithium Extraction (DLE) technology and the dramatic increase in lithium demand and pricing driven by global battery manufacturing.
Highest Concentrations in North America: Smackover brine lithium levels of 400-800+ ppm far exceed other North American brine deposits, improving extraction economics significantly.
Existing Infrastructure: Decades of oil, gas, and bromine production have created roads, pipelines, wells, processing facilities, and a skilled workforce already in place.
Co-Production Potential: Lithium can be extracted from brine that is already being produced for bromine or oil and gas operations, creating additional revenue streams from existing wells.
Domestic Supply: The United States currently imports the vast majority of its lithium. Smackover production could significantly reduce this dependency and create a major domestic supply chain.
Massive Scale: With up to 19 million tons of lithium estimated in Arkansas alone, the Smackover has the resource base to support large-scale, long-term production across multiple operators.
Major Company Investment: ExxonMobil, Equinor, Standard Lithium, and Tetra Technologies have collectively invested billions of dollars in Smackover lithium development, validating the commercial potential.
Direct Lithium Extraction is the breakthrough technology making Smackover lithium commercially viable. Unlike traditional lithium production methods that require massive evaporation ponds in arid climates (as used in Chile and Argentina), DLE uses chemical or physical processes to selectively extract lithium from brine in a matter of hours rather than months. This technology is ideally suited to the Smackover Formation's high-concentration brines and humid Gulf Coast climate where evaporation ponds would be impractical.
The DLE process begins by pumping lithium-bearing brine from the Smackover reservoir to the surface using conventional oil and gas production methods — the same wells, pumps, and infrastructure used for decades. At the surface, the brine passes through a DLE processing plant where selective sorbents, ion exchange resins, or membrane systems capture the lithium ions while allowing other dissolved minerals to pass through.
The concentrated lithium solution is then processed into battery-grade lithium carbonate or lithium hydroxide, while the depleted brine — still containing bromine and other minerals — is either reinjected into the formation or sent to additional processing for bromine recovery.
Speed: Lithium extracted in hours, not the 12-18 months required by evaporation ponds
Water Efficiency: Brine is reinjected after extraction, minimizing water consumption and surface impact
Co-Production: Can operate alongside existing oil, gas, and bromine production using shared infrastructure
Small Footprint: Processing plant requires a fraction of the land area of evaporation ponds
High Recovery: Modern DLE achieves 90%+ lithium recovery rates from processed brine
Climate Independent: Works in humid Gulf Coast climate where evaporation ponds are not viable
Pump lithium-rich brine from Smackover reservoir at 7,000-12,000+ feet using conventional wells
Brine passes through sorbent or ion exchange system that selectively captures lithium ions
Concentrated lithium solution converted to battery-grade lithium carbonate or lithium hydroxide
Depleted brine reinjected into formation or sent to bromine recovery, maintaining reservoir pressure
Multiple DLE technology approaches are being deployed in the Smackover. Standard Lithium has operated a DLE demonstration plant at the LANXESS bromine facility in El Dorado, Arkansas for over five years, producing small batches of lithium chloride and validating the commercial process. ExxonMobil is deploying its own proprietary DLE technology through its Saltwerx subsidiary. Each company's approach is tailored to the specific brine chemistry and production conditions of their respective acreage positions.
Billions of dollars are being invested in Smackover lithium development by some of the world's largest energy and mining companies. These projects represent the most advanced lithium-from-brine developments in the United States and are reshaping the value of mineral rights across the Smackover trend.
ExxonMobil has made the single largest investment in Smackover lithium, acquiring over 300,000 net acres of brine rights across the formation since early 2023. Operating through its Saltwerx subsidiary, ExxonMobil is applying its decades of subsurface expertise and operational scale to lithium extraction. The company drilled its first dedicated lithium well in Arkansas in late 2023 and completed appraisal drilling programs to delineate the resource.
In April 2025, the Arkansas Oil and Gas Commission approved ExxonMobil's 56,245-acre Pine Unit for brine production in Columbia County. The company plans to use conventional oil and gas drilling methods to access lithium-rich brine from Smackover reservoirs approximately 10,000 feet underground, then apply proprietary DLE technology to separate lithium from the saltwater.
ExxonMobil is targeting first lithium production by 2027 and aims to produce enough lithium to supply more than one million electric vehicle batteries per year by 2030. Saltwerx projects it can generate $27 million in annual profit from producing 165,000 barrels of lithium brine daily. This represents one of the largest industrial investments in Arkansas history and has fundamentally changed the value proposition for mineral owners in Columbia and Union counties.
Smackover Lithium is a joint venture formed in May 2024 between Standard Lithium Ltd. (55% working interest) and Norwegian energy giant Equinor (45% working interest). This partnership combines Standard Lithium's five years of DLE operational experience at its El Dorado, Arkansas demonstration plant with Equinor's financial strength and large-scale project development expertise.
The joint venture is developing two major projects. The South West Arkansas Project completed a positive Definitive Feasibility Study in 2025, with construction expected to begin in 2026 and first commercial operations targeted for 2028. In March 2026, Smackover Lithium signed its first binding commercial offtake agreement with Trafigura Trading LLC to supply 8,000 metric tonnes per year of battery-quality lithium carbonate over a 10-year period.
The Franklin Project in East Texas holds an inferred resource of approximately 2.16 million metric tonnes of lithium carbonate equivalent at an average concentration of 668 mg/L, with the Pine Forest 1 well recording a lithium brine concentration of 806 mg/L — the highest reported in North America. The joint venture aims to reach production of more than 100,000 tonnes of lithium chemicals per year in Texas through multiple development phases.
Separate from the Smackover Lithium JV, Standard Lithium is developing its Phase 1A commercial lithium plant at the LANXESS bromine facility in El Dorado, Arkansas. This project leverages LANXESS's existing Smackover brine production infrastructure — one of the world's largest bromine operations — to feed a commercial-scale DLE plant.
LANXESS will supply lithium-bearing brine from its existing production wells and lease land to Standard Lithium for the processing facility. Standard Lithium has operated a DLE demonstration plant at the El Dorado site for over five years, processing Smackover brine and producing lithium chloride samples. The definitive feasibility study showed positive economics, and Standard Lithium expects to start commercial plant construction in mid-2026, backed by signals of interest from three export credit agencies for more than $1 billion in senior secured debt.
Tetra Technologies holds significant Smackover brine leases across south Arkansas and is positioned as both a brine lease holder and a bromine/lithium producer. Tetra's maiden inferred resource estimate included 5.25 million tons of elemental bromine and 234,000 tons of lithium carbonate equivalent on its acreage.
In April 2025, the Arkansas Oil and Gas Commission approved expansion of Tetra's Evergreen Unit from 6,138 to 6,953 gross acres, with test wells showing lithium concentrations above estimated averages. Tetra also holds the brine leases underlying the 20,854-acre Reynolds Brine Unit, which is operated by Smackover Lithium (Standard Lithium/Equinor JV) for lithium extraction. Under this arrangement, Tetra receives a 2.5% royalty on gross lithium revenues while retaining rights to bromine and all other non-lithium minerals.
Galvanic Energy: Focused on East Texas Smackover lithium exploration, assembling acreage positions in the eastern portion of the lithium trend where some of the highest brine concentrations have been reported.
Albemarle Corporation: The world's largest lithium producer operates bromine extraction facilities in Arkansas using Smackover brine. While currently focused on bromine, Albemarle's existing Smackover brine infrastructure positions it as a potential lithium producer.
SWN Energy (Southwestern Energy): Holds legacy acreage positions across the Smackover trend in Arkansas with brine rights that could be developed for lithium extraction or leased to lithium-focused operators.
Private Operators: Numerous smaller companies and private mineral owners hold Smackover brine and mineral rights across the trend. As the lithium opportunity matures, these positions are attracting increasing acquisition interest from both major and junior lithium developers.
The discovery of commercially viable lithium concentrations in Smackover brines has created an entirely new value component for mineral rights owners across the formation's footprint. Understanding how lithium rights interact with traditional oil and gas mineral ownership is essential for anyone holding minerals in the Smackover trend.
Whether a mineral owner holds the rights to subsurface lithium depends on state law and the specific language of the mineral deed or conveyance. In general, the mineral estate includes the right to extract minerals from the subsurface, but the definition of what constitutes a "mineral" varies by jurisdiction and by deed language.
Mineral rights in the Smackover area may include rights to subsurface brines and the dissolved minerals they contain, but this is an area of evolving law that depends on specific facts and circumstances. A thorough title review is essential.
Arkansas: Lithium dissolved in subsurface brine is generally considered part of the mineral estate and owned by the mineral rights holder. The Arkansas Oil and Gas Commission has set an industry royalty rate of 2.5% for brine mineral extraction.
Texas: The classification of brine minerals including lithium under Texas law is still evolving. Texas courts have historically distinguished between "minerals" and "water" in the subsurface, and the classification of dissolved lithium in formation brine remains an active area of legal development.
Existing oil and gas leases may or may not cover lithium extraction, depending on the specific lease language. Many traditional oil and gas leases grant the lessee the right to extract "oil, gas, and other minerals" or "oil, gas, and all other minerals." Whether "other minerals" includes lithium dissolved in brine is a question that depends on the exact wording and applicable case law.
Some Smackover leases specifically address brine rights, while others are silent on the topic. Mineral owners should carefully review their lease documents to understand what rights have been conveyed and what rights they may retain.
The entry of ExxonMobil, Equinor, and other major companies into Smackover lithium has created significant new demand for mineral and brine rights in the trend. Acreage that was previously valued solely on its oil and gas production or potential now carries an additional lithium premium, particularly in Columbia, Union, Lafayette, and Calhoun counties in Arkansas and Cass and Marion counties in Texas.
Buckhead Energy has the expertise to evaluate both traditional production value and lithium brine potential when assessing Smackover mineral rights, ensuring that owners receive offers that reflect the full value of their position.

The economic picture for Smackover mineral rights is now a dual story: traditional oil and gas production economics that have driven mineral values for decades, plus the emerging lithium economics that are adding an entirely new dimension of value.
Most active Smackover oil and gas fields are mature, with many on enhanced recovery operations. While individual well production rates are often modest compared to newer shale plays, the long production histories and predictable decline curves provide stable, reliable income streams for mineral owners.
Waterflood operations extend productive life 20-40+ years
Mature field economics are well-understood with predictable cash flows
Low operating costs due to established infrastructure and paid-out wells
HBP acreage in many fields held by continuous production for decades
Lithium is a high-value industrial mineral with strong global demand driven by battery manufacturing. The Smackover's high brine concentrations and existing infrastructure create a potentially favorable cost structure compared to other lithium sources worldwide.
Battery-grade lithium carbonate trades at $10,000-$80,000+ per metric tonne depending on market conditions
DLE cost structure benefits from existing wells, roads, and processing infrastructure
Co-production with bromine allows shared infrastructure and operating costs
Long-term offtake agreements (10+ years) provide revenue certainty for operators
What makes Smackover mineral rights particularly compelling today is the combination of established oil and gas production value with emerging lithium potential. A mineral owner in Columbia or Union County, Arkansas may hold interests that generate current royalty income from conventional oil and gas production while sitting atop one of the largest lithium deposits in North America. This dual-value proposition is unique to the Smackover trend and creates opportunities that Buckhead Energy is well-positioned to evaluate.
Valuing Smackover Formation mineral rights requires expertise in both traditional petroleum engineering economics and the emerging lithium brine landscape. Buckhead Energy evaluates the following key factors when assessing Smackover mineral rights:
Traditional Oil & Gas Production: Current production volumes, decline rates, operating expenses, and remaining reserves from conventional Smackover wells
Lithium Brine Potential: Proximity to known lithium projects, estimated brine concentrations based on regional data, and position within the commercially prospective trend
Brine Rights Ownership: Whether the mineral estate includes subsurface brine rights under applicable state law and deed language
Lease Language Analysis: Whether existing oil and gas leases cover lithium extraction or if brine mineral rights are reserved to the mineral owner
County Location: Columbia and Union counties (AR) and Cass County (TX) command the highest lithium premiums; proximity to ExxonMobil and Smackover Lithium acreage is a key factor
Formation Depth & Brine Quality: Smackover depth, reservoir quality, and known or estimated lithium concentrations in the brine
Proximity to Major Projects: Distance from ExxonMobil's Pine Unit, Smackover Lithium's operations, and Tetra Technologies' brine units
HBP Status: Whether acreage is held by production under existing leases, and the terms and remaining life of those leases

Get Your Free ValuationMineral owners across the Smackover trend have a variety of reasons for considering a sale. The unique combination of traditional production and emerging lithium potential creates a window where the value of Smackover minerals is in flux — and many owners are choosing to capitalize on the current moment.
The lithium rights landscape is evolving rapidly, with new regulations, unit approvals, and legal interpretations emerging regularly. For mineral owners who prefer certainty over uncertainty, selling provides a clear outcome while the legal and regulatory framework continues to develop.
Major lithium projects are still in the exploration and development phase, with commercial production not expected until 2027-2028 at the earliest. Selling during the pre-production phase allows mineral owners to lock in value based on demonstrated resource potential before production results — positive or negative — are known.
Questions about who owns lithium in brine, whether existing leases cover lithium extraction, and how royalties will be calculated are being answered in real time by courts, legislatures, and regulatory agencies. Some mineral owners prefer to monetize their position rather than wait for these questions to be fully resolved.
Buckhead Energy understands both traditional Smackover oil and gas values and the emerging lithium opportunity. Our evaluation process accounts for the full spectrum of Smackover mineral value, from current production income to lithium brine potential, ensuring sellers receive fair offers that reflect the complete picture.
The Smackover Formation is an Upper Jurassic-age carbonate and evaporite geological formation deposited approximately 155 to 145 million years ago. Named after the town of Smackover, Arkansas in Union County, it extends across the Gulf Coast subsurface from East Texas through south Arkansas, north Louisiana, Mississippi, Alabama, and into the Florida panhandle. The formation consists of three members: a lower organic-rich source rock, a middle oolitic grainstone reservoir, and an upper dense limestone and anhydrite seal. It has been one of the most important oil and gas producing formations in the Gulf Coast for nearly a century and is now recognized as containing one of the largest lithium brine deposits in North America.
Yes. The Smackover Formation contains lithium dissolved in subsurface brines at commercially viable concentrations, typically ranging from 100 to over 800 parts per million. A landmark 2024 USGS study using machine learning estimated between 5.1 and 19 million tons of lithium in Smackover brines in southern Arkansas alone, representing 35 to 136 percent of the entire current U.S. lithium resource estimate. The highest concentration reported in North America — 806 mg/L — was measured from a Smackover well in East Texas. Multiple major companies including ExxonMobil and Standard Lithium are investing billions to extract this lithium using Direct Lithium Extraction (DLE) technology.
As of 2026, no company is yet at full commercial-scale lithium production from the Smackover, but several major projects are advancing rapidly. ExxonMobil (through its Saltwerx subsidiary) has acquired over 300,000 acres of brine rights and is targeting first production in 2027. Smackover Lithium, a joint venture between Standard Lithium and Equinor, plans to begin construction in 2026 with commercial operations in 2028, and has signed a 10-year offtake agreement with Trafigura. Standard Lithium has operated a DLE demonstration plant at the LANXESS bromine facility in El Dorado, Arkansas for over five years. Tetra Technologies holds significant brine leases and is developing both bromine and lithium production from its Smackover acreage.
Whether you own lithium rights depends on your state's laws and the specific language of your mineral deed or conveyance. In Arkansas, lithium dissolved in subsurface brine is generally considered part of the mineral estate, meaning the mineral rights owner typically holds the lithium rights. In Texas, the legal classification of dissolved lithium in formation brine is still evolving. Additionally, existing oil and gas leases may or may not convey lithium extraction rights depending on the specific lease language. Some leases covering "oil, gas, and all other minerals" may include lithium, while others may not. A professional title review is essential to determine the status of lithium rights on any specific property.
In Arkansas, Columbia County and Union County are the epicenter of Smackover lithium development. Columbia County is home to ExxonMobil's approved Pine Unit and the Smackover Lithium South West Arkansas Project, while Union County hosts Standard Lithium's DLE demonstration plant and planned Phase 1A commercial facility at El Dorado. Lafayette and Calhoun counties also show strong lithium brine potential. In East Texas, Cass County is emerging as a premier target, with Smackover Lithium's Franklin Project reporting brine concentrations up to 806 mg/L — the highest in North America. Marion and Harrison counties also lie along the East Texas lithium trend.
Smackover mineral rights valuation involves evaluating multiple factors including current oil and gas production (if any), decline rates and remaining reserves, proximity to known lithium development projects, brine rights ownership status, existing lease language and terms, county location within the lithium trend, formation depth and estimated brine quality, HBP status, and proximity to ExxonMobil, Standard Lithium, or Tetra Technologies acreage. The emerging lithium potential has added a significant new value component that requires specialized knowledge to properly assess. Buckhead Energy's evaluation process accounts for both traditional production economics and lithium brine potential.
Yes. Mineral rights can be sold at any time regardless of whether active production or extraction is occurring. Many mineral owners in the Smackover trend are choosing to sell during the current pre-production phase, when major companies have demonstrated the resource potential but commercial-scale extraction has not yet begun. Buckhead Energy evaluates both current production value and future lithium potential when making offers, and does not require active lithium production to purchase Smackover mineral rights. The current period represents a unique window where significant company investment has validated the lithium resource, creating real value that can be monetized through a sale.
Buckhead Energy has deep expertise in evaluating both traditional oil and gas mineral rights and the emerging lithium brine potential across the Smackover Formation.
