A History of Success in the Midland Basin

In 1979, Autry C. Stephens formed a sole proprietorship and drilled his first well, the McClintic B-30 #2, in the Spraberry Field of Midland County. Stephens immediately recognized opportunities and began strategically acquiring producing oil and gas properties and drilling more wells.

As others fled the market during downturns, Stephens bought additional leasehold and several corporate acquisitions adding tremendous value to his proprietorship.

In 2000, Stephens transformed his sole proprietorship into Endeavor Energy Resources, LP.

Over the years, his continued focus led to building multiple service companies that include roustabout, trucking, well service, wireline, vehicle maintenance, and construction services. This vertical integration business model has consistently provided steady access to energy services for his drilling and production operations.

In 2016, Stephens brought on new leadership to continue his vision and growth for Endeavor. During this time, the company began its transition from a predominately vertical driller to a leading top-tier horizontal operator in the Midland Basin.

Since implementing the new horizontal drilling program, the Endeavor team has completed 1,100+ gross operated horizontal wells and produces more than 400,000 gross operated barrels of oil equivalent per day. (Based on 2-stream reporting. Natural gas converted to oil on a 6:1 conversion ratio).

The company continues to focus on developing its core assets by incorporating industry-leading drilling and completion techniques to reduce drill time, lower lease operating expenses, and achieve record production.

Today, Endeavor has more than 1,200 valued employees and is one of the largest private oil producers in the Lower 48.
