Conroe Oil Field Mineral Rights in Montgomery County, Texas

Owner-focused context on the Conroe oil field — discovery history, Cockfield geology, and how to start a free written offer on a mineral or royalty interest.

Quick Answer

The Conroe oil field is a Montgomery County, Texas, Gulf Coast salt-dome field discovered by George W. Strake on December 13, 1931. It produces primarily from Eocene Cockfield sands near about 5,000 feet and had produced more than 717 million barrels of oil by January 1, 1993 (Texas State Historical Association). Buckhead Energy has been buying mineral and royalty interests since 2006. Buckhead provides a free written offer.

What is the Conroe oil field?

The Conroe oil field sits in south-central Montgomery County, Texas, on the Texas Gulf Coast north of Houston. It is an elliptical producing area overlying a deep-seated, faulted salt-dome structure. For mineral owners, “Conroe” usually means an interest under that historic field — whether still producing, held under an older lease, or inherited through multi-generation title.

Public historical summary: Handbook of Texas Online — Conroe Oilfield (Texas State Historical Association). Field well counts and operator snapshots also appear on Buckhead’s Conroe field data page when available.

Discovery and early development

Independent wildcatter George W. Strake assembled acreage after larger companies had largely walked away from geophysical prospects that did not show a shallow dome. He spudded the Strake No. 1 South Texas Development Company well in August 1931. On December 13, 1931, that well came in as a gas-and-condensate discovery from Cockfield sands near 5,033 feet.

Oil-rate confirmation followed on June 5, 1932, when Strake’s No. 2 well flowed about 900 barrels of oil per day from the Main Conroe sand. Development accelerated through 1932–1934 under Railroad Commission spacing and allowable rules. The field’s early flush production helped re-establish the Texas Gulf Coast as a major oil province after decades of prospecting (TSHA).

Many present-day Conroe-area mineral and royalty interests still trace to Depression-era leases and conveyances — often through heirs several generations later. Confirming what you own usually starts with deed, probate, and division-order records rather than city or surface ownership alone.

Geology and reservoir character

Primary historical pays are Eocene-age Cockfield (Upper Cockfield and Main Conroe) sandstones at roughly 5,000–5,300 feet. The trap is structural — crestal arching over a deep-seated salt dome cut by faults — rather than a classic piercement overhang.

Rock quality: historically strong porosity and permeability in connected Cockfield sands

Drive: strong water drive and gas-cap expansion in early life; later pressure maintenance with gas and water injection

Unitization: TSHA notes the field was unitized in 1978 while retaining twenty-acre spacing conventions from early conservation practice

Production history owners should understand

Conroe is a mature, long-life field. TSHA reports cumulative crude production of more than 717 million barrels between discovery and January 1, 1993. Early-year allowables and blowouts created dramatic daily rates in 1933, but those figures are not a modern per-well or per-interest forecast.

1931–1940s: discovery, rapid development, proration, and early pressure observation

Mid-century onward: pressure maintenance with gas and water injection; declining primary rates with long secondary-recovery life

Today: remaining production and royalty checks vary by tract, decimal interest, operator, and well status — review your own stubs and public RRC records rather than field averages

What affects an evaluation of a Conroe interest

Buyers look at facts about your interest, not a single field-wide price. Buckhead does not publish acre-based price lists or personalized value estimates on this page. Factors that commonly matter include:

Interest type and net revenue / royalty fraction

Producing vs. non-producing status and recent well performance

Operator activity and nearby development context

Lease terms and title clarity (including inherited or fractional ownership)

Commodity conditions and remaining recovery expectations for that tract

Documents that help start an offer review

You do not need a perfect file to start a conversation. Helpful items include a recent royalty statement or check stub, a division order, a deed or probate papers, and the lease if you have it — plus county, operator, and well or unit names when known.

Intake: A recent royalty statement, division order, or deed helps when you have them. If you do not, start with the county, operator, and what you know about the interest - Buckhead can work from limited information.

George W. Strake's Strake No. 1 South Texas Development Company discovery well came in on December 13, 1931, initially as gas and condensate from the Cockfield. A June 5, 1932 confirmation well established large oil rates from the Main Conroe sand. Source: Handbook of Texas Online (TSHA), “Conroe Oilfield.”
