Phillips Alaska Inc. has reported to the Alaska Oil and Gas Conservation Commission on the Spark 1 and Spark 1A exploration wells drilled over the winter in the National Petroleum Reserve-Alaska. The company has now reported on three of the four winter NPR-A exploration holes.
The Spark 1 was drilled to a measured depth of 8,850 feet and a total vertical depth of 8,846 feet. Drilling was completed April 12; status is plugged and abandoned.
The sidetrack, the Spark 1A, is reported as suspended. That well, drilled from the same surface pad, reached a measured depth of 8,522 feet and a true vertical depth of 8,445 feet. The sidetrack has a bottom hole location some 630 feet farther south than the bottom hole in the original well. Drilling was completed at the location April 29.
The Spark wells are some 15 miles west, northwest of Nuiqsut.
ARCO Alaska Inc. previously reported that the Clover A well reached a measured depth of 8,570 feet and a true vertical depth of 8,567 feet. Drilling on that well was completed April 21; status is plugged and abandoned.
The Clover A surface location is some five miles west of Nuiqsut.
ARCO Alaska also permitted the Rendezvous A well in the NPR-A in early April; no results have yet been reported for that location, some 16 miles west of Nuiqsut.
Phillips Alaska and its partner Anadarko Petroleum Corp. completed three wells and a sidetrack in the National Petroleum Reserve-Alaska this year, Phillips Alaska President Kevin Meyers told the Anchorage Chamber of Commerce May 22. The companies are not ready to make an announcement about drilling results, Meyers said: "I'll just tell you this: we'll be back there next year because we were encouraged."
Phillips Alaska spokeswoman Dawn Patience confirmed June 13 that no drilling results were being released for the NPR-A wells.
The commission releases only location, depth and status information upon well completion. Unless confidential status is approved, complete well results are released 25 months after completion.
