A three-well pilot horizontal well program was recently implemented at the North Central Levelland Unit (NCLU) in Cochran and Hockley counties, Texas. Short radius technology was utilized to drill two injection wells and one producer. Horizontal lateral length ranged from 500" to 700". Primary objectives of the program were to increase injection and production rates and increase waterflood sweep efficiency. Horizontal technology could also be instrumental in improving the economics of a future carbon dioxide (C02) flood. This paper discusses the theoretical reasons for drilling horizontal wells at NCLU as well as the actual drilling and completion of the wells.
