# Conroe Oil Unit Mineral Rights — Montgomery County, Texas

## TL;DR

The Conroe Oilfield in Montgomery County, Texas, is one of the largest oil discoveries of the 1930s, with cumulative production exceeding 700 million barrels since its 1931 discovery by wildcatter George W. Strake. The field has been on continuous waterflood since 1980, producing from the Cockfield Sandstone formation and providing small, predictable monthly royalty payments to mineral owners across generations. Many current mineral interests trace back to original 1929-1932 leases inherited through four to five generations.

## Key Takeaways

- **Historic discovery field**: Discovered in June 1931 by George W. Strake; became one of the largest U.S. oil discoveries of the 1930s, producing over 60,000 BOPD at peak
- **Massive cumulative production**: More than 700 million barrels produced from the Cockfield Sandstone formation at depths of 5,000-5,300 feet
- **Long-life waterflood economics**: Field has been on continuous secondary recovery via waterflood since 1980, generating small but predictable monthly checks for decades
- **Faulted anticline trap**: Produces from Eocene-age Cockfield Formation sandstones with 20-30% porosity associated with the Conroe salt dome structure
- **Multi-generational ownership**: Many current mineral interests stem from original 1929-1932 leases, now inherited four to five generations deep
- **Stable production history**: Transitioned from primary depletion (1931-1945) to gas reinjection (1945-1980) to modern waterflood operations (1980-present)
- **Depression-era boom legacy**: The discovery placed Montgomery County at the center of the Texas oil boom and built much of present-day Conroe's infrastructure

## Page Highlights

**Field Location & Overview**: The Conroe Oilfield sits in Montgomery County, Texas, immediately north of Houston. It rapidly grew into one of the largest U.S. oil discoveries of the 1930s after its June 1931 discovery.

**Geology & Reservoir Characteristics**: The field produces from Eocene-age Cockfield Formation sandstones at 5,000-5,300 feet depth. The trap is a faulted anticline associated with the Conroe salt dome, featuring multiple stacked sandstone reservoirs with 20-30% porosity and good permeability.

**Production History**: The field evolved through three distinct phases—primary depletion (1931-1945), gas reinjection for pressure maintenance (1945-1980), and large-scale waterflood operations (1980-present)—providing stable, long-life production.

**Discovery by George W. Strake**: Wildcatter George W. Strake discovered the field after purchasing mineral leases in the late 1920s when major oil companies considered the area non-productive. His persistence made him one of Texas's wealthiest individuals.

**Modern Mineral Ownership**: The page positions Conroe as a textbook long-life waterflood property generating small monthly checks over many decades, with Buckhead Energy offering free valuations for producing or dormant interests.
