Area of Operations

Trey has researched, identified, developed and divested several oil and gas properties during its history. We began our latest growth phase through the acquisition and production of both conventional and unconventional resources in Texas and Oklahoma. The primary assets of Trey Resources I are focused in the Mid-Continent and Permian Basin.


Trey’s primary focus in the Mid-Continent is the Hunton Limestone. This formation stretches for over 2.7 million acres mainly in Oklahoma, but also in the neighboring states of Texas, New Mexico and Arkansas. Production from the Hunton Limestone is characterized largely by high quality oil production and the associated production of high BTU content natural gas.

In 2014, Trey Resources I acquired 12,000 acres in the Short Junction Field in Cleveland County, OK. The Field was originally discovered by Conoco in 1948 and was developed using vertical wells drilled on a 40 acre well spacing, resulting in oil and gas production from 270 active wells within the 12,000 acre leasehold. Conoco sold the Field in 1988 after producing over 23 million barrels of oil. The Field changed ownership several times over the years before finally being acquired by Trey. This acquisition continues Trey’s long history in Oklahoma City – we have been operating oil and gas properties within Oklahoma City limits dating back to 1988.

Permian Basin

In the Permian Basin, Trey is focused on the San Andres formation. The San Andres is a relatively heterogeneous platform carbonate that until recently has been produced vertically on the eastern side of the Central Basin Platform.

In 2014, Trey Resources I acquired over 5,000 acres in the Shafter Lake Field in Andrews County, Texas. The Field was discovered in 1930 and has produced about 58 million barrels of oil. Expansion of the Field continued into the early 1980s when existing methods of extraction had exhausted the oil available for recovery. Today, utilizing improved technology, this Field is experiencing renewed activity – there are currently about 700 producing wells across 24,000 acres. Throughout our history, Trey has a strong track record of acquiring assets that others thought had minimal remaining recoverable oil, applying new techniques and delivering increased value. Results to date in the Shafter Lake Field are promising that Trey has found another asset with significant potential.
