Spraberry Play Overview

The Spraberry field was discovered in 1935 and extends over several counties in West Texas comprising about 1.6 million acres. The field is 150 miles long and 75 miles wide, and it has undergone much change and expansion over the years, both aerially and vertically. The correlative interval is now over 3,500 feet thick and includes the Clearfork, Upper Spraberry, Lower Spraberry, Dean, and Wolfcamp formations. These formations are correlative over the area, but are lenticular in nature and vary in thickness, porosity, and permeability even over short distances. The general completion technique includes hydraulic fracturing and installation of sucker rod pumps.

The Permian (Leonardian) Spraberry and Dean sandstones have produced oil throughout the Midland Basin since the late 1940's. Known as the Spraberry Trend, productive areas extend across 18 counties and contain more than 10 Bbbl of oil. More recently, operators have been including deeper formations in their Spraberry Trend completions: first the Wolfcamp (Permian) that underlies the Dean and then deeper zones in the Pennsylvanian.
