Driller Sees Success Converting Vertical Wells to Horizontalby Will Brackett
The oil patch version of teaching an old dog new tricks is resulting in success for one San Antonio-based oil company.
“When we acquired Brushy Resources, it had some vertical wells,” said Avi Mirman, chief executive officer of Lilis Energy, in a phone interview.
Those vertical wells were in an old gas field, so the company cut windows in the wellbores to go horizontal. The work resulted in what Lilis Energy calls industry-leading flow rates per 1,000 foot lateral feet in its first two operated horizontal wells.
The Bison #1H, which Mirman described as originally a deep vertical well, was turned to sales on Jan. 19 and had a recent 24-hour rate of 2,128 barrels of oil equivalent per day, or 344 BOEPD per 1,000 foot lateral feet, 75 percent liquids. The well’s 6,897-foot lateral was completed with 35 stages — 200-foot plug to plug spacing — with approximately 2,200 pounds of sand per foot.
Lilis currently has two other horizontal wells — the Hippo #1H, which has begun flow testing, and the Lion #1H, which is waiting to be hydraulically fractured and completed.
