Recent drilling activity in the War-Wink area of west Texas has established a new play in submarine channel and levee/overbank sandstones of the middle and lower Cherry Canyon Formation, Delaware Mountain Group (Guadalupian). Previous exploration and development, spanning the 1960s, 1970s, and early 1980s, had focused on the upper part of the formation. The new play, located a few miles west of the Central Basin platform, suggests the existence of multiple channel trends not yet explored in the Delaware basin. Entrapment in the War-Wink area is related to both structural and stratigraphic factors. Lower Cherry Canyon reservoirs have porosities ranging from 18 to 24% and permeabilities ranging from 10 to 60 md and thus are higher in quality than reservoirs of the underlying Brushy Canyon Formation. Core data indicate that permeabilities increase rapidly above a threshold porosity value of about 18%. Lower Cherry Canyon wells are completed by fracture stimulation in one or two main reservoir zones, with several secondary zones commonly behind pipe. Wells usually flow at rates of 100-200 bbl oil per day for up to 1 yr before being put on pump. Main producing zones are capable of recoveries ranging from 50,000 to 120,000 bbl. Attempts at using horizontal drilling in place of fracture stimulation have proved highly successful in certain cases. Use of this approach for Cherry Canyon development, guided by good geologic control, may provide an excellent technique applicable to many portions of the Delaware basin.
