Parsley Energy Inc is an independent oil and natural gas company that focuses on the acquisition, development, and exploitation of unconventional oil and natural gas reserves. The company grows reserves and production through development, exploitation, and drilling of its multiyear inventory of drilling locations. Parsley chooses to operate nearly all the wells it has interest in. Equipment and personnel are received from independent contractors, but the company employs its own crew to improve production rates, increase reserves, and lower the cost of operating their oil and natural gas properties. Traditionally, Parsley’s properties have been acquired through oil and natural gas lease agreements that provide royalties to the original mineral owners of the property.
