ExxonMobil Corp. drilled the Sacate Sa-2 well from its Heritage platform offshore California in 1,075 ft of water in May 2000, which the company believes set the North American record for ERD (extended-reach drilling). Being the fourth ERD well drilled by ExxonMobil over the past 2 years in the SYU (Santa Ynez Unit), the Sa-2 reached a HD (horizontal displacement) of 21,277 ft with a 24,660 ft MD (measured depth) and a 6,704 ft TVD (total vertical depth). The company is using ERD technology to develop an otherwise marginal oil field. The Sacate field, with an estimated ultimate recovery of about 50 million boe, was not attractive for development with a new deepwater platform or subsea wellheads. In addition, the environmentally sensitive Santa Barbara Channel challenged the development project to minimize offshore structures. Utilizing ERD technology combined with modest investments to upgrade the existing Heritage drilling rig and production facilities, however, has resulted in an attractive project.
