Hoy No. 1 Oil Well was constructed by the Sinclair Oil & Refining Corporation in September 1916.  It has been listed on the National Register of Historic Places since 1986.  Milton C. Garber and his brother Bert Garber hired geologist Dorsey Hager to determine potential drilling locations on their properties.  The Garber brothers contracted Harry F. Sinclair to construct a well on R. E. Hoy's farm (NE corner, Section 25, T22N, R4W, National Iranian Drilling Company (NIDC) is an Iranian company.

Pride International, Inc. was an offshore oil drilling company headquartered in Houston, Texas, the United States.  With over 7000 employees, Pride provided contract drilling and related services to oil and gas companies worldwide.  It had positioned its fleet to operate offshore with more than 50 units in five continents.  Its largest operations included those in Angola, Brazil, India, Mexico and Saudi Arabia.  Pride spun off its mat jackups as a public company called Seahawk Drilling in August 2009, so the company's focus is primarily deep-water drilling along with some high-spec jackups. Fred M.

Sinclair Oil Corporation is an American petroleum corporation, founded by Harry F. Sinclair on May 1, 1916, as the Sinclair Oil and Refining Corporation by combining the assets of 11 small petroleum companies.

As of 2013 the Cline Shale, also referred to as the "Wolfcamp/Cline Shale", the "Lower Wolfcamp Shale,", or the "Spraberry-Wolfcamp shale", or even the "Wolfberry", is a promising Pennsylvanian oil play east of Midland, Texas which underlies 10 counties: Fisher, Nolan, Sterling, Coke, Glasscock, Tom Green, Howard, Mitchell, Borden and Scurry County, Texas.  Exploitation is projected to rely on hydraulic fracturing. an organic rich shale, with Total Organic Content (TOC) of 1-8%, with silt and sand beds mixed in.  It lies in a broad shelf, with minimal relief and has nice light oil of 38-42 gravity with excellent porosity of 6-12% in thickness varying 200 to 550 feet thick.  The total recovery was estimated to 30 billion barrels in 2012, and United States Geological Survey estimated the technically recoverable reserve to 20 billion barrels in 2016, the largest USGS estimate ever and nearly three times larger than that of the 2013 USGS Bakken-Three Forks resource assessment in North Dakota.  The field also seems to contain 16 trillion cubic feet of natural gas.  This is the first assessment of continuous resources in the Wolfcamp shale in the Midland Basin portion of the Permian.  During the 1980s, vertical wells produced oil in the Wolfcamp area.  However, since 2000 in North America, horizontal drilling or porpoising along with hydraulic fracturing have grown tremendously and are tapping the continuous oil reserve.  In Odessa, Chris Schenk, a Denver-based research geologist and assessment team member, told KWES, "This oil has been known there for a long time -- our task is to estimate what we think the volume of recoverable oil is."  According to Morris Burns, a local oil expert and former president of the Permian Basin Petroleum Association, 50% to 60% is recoverable beginning at a price range of $60 to $65 per barrell.  This area is the largest continuous oil discovery in the United States and encompasses the cities of both Lubbock and Midland which are 118 miles apart.
