An owner's guide to the Conroe oilfield — Montgomery County, Texas — one of the giants of the 1930s East Texas oil boom and a long-life waterflood field today.
Get Your Free Mineral ValuationThe Conroe Oilfield sits in Montgomery County, Texas, immediately north of Houston. Discovered in June 1931 by wildcatter George W. Strake, the field grew rapidly into one of the largest U.S. oil discoveries of the 1930s. At its peak, the field produced over 60,000 BOPD; cumulative production has exceeded 700 million barrels.
The Conroe field's discovery placed Montgomery County at the center of the Depression-era Texas oil boom and built much of the early infrastructure of present-day Conroe (the city). For mineral owners, the field is a textbook long-life waterflood — small monthly checks for many decades.
The Conroe field produces from the Eocene-age Cockfield Formation at depths of approximately 5,000-5,300 ft TVD. The trap is a faulted anticline associated with the Conroe salt dome, with multiple stacked sandstone reservoirs in the Cockfield producing at different depths within the structure.
Lithology: sandstone reservoirs with high porosity (20-30%) and good permeability
Trap type: faulted anticline associated with salt dome uplift
Production type: oil with associated solution gas
1931-1945: primary depletion drive; rapid early production followed by reservoir pressure decline
1945-1980: pressure maintenance via gas reinjection; production stabilized
1980-present: large-scale waterflood; field has been on continuous secondary recovery for 40+ years
Conroe was discovered by George W. Strake, a Houston wildcatter who had purchased mineral leases in Montgomery County during the late 1920s when most major oil companies considered the area non-productive. Strake's persistence and the success of his Strake No. 1 well in 1931 made him one of the wealthiest individuals in Texas and established Montgomery County as a major oil-producing region. Many current Conroe-area mineral interests trace original 1929-1932 leases to the Strake-era acquisition program.
