On Feb. 9, Eni US Operating Co. asked the State of Alaska for authorization to drill two additional wells at its North Slope Maggiore prospect. Eni told the Division of Oil and Gas that it has already drilled three wells this season, two in its Rock Flour prospect (No. 2 and 3) and one at Maggiore (No. 1) from a “snow/ice road system snow/ice road system that travels south from existing facilities and infrastructure at Kuparuk River Unit MP 1.”
The Rock Flour prospect is adjacent to the southeast corner of the Kuparuk River unit and directly south and west of the Prudhoe Bay unit boundary. Boundary to boundary Maggiore is about four miles south of Rock Flour.
The two additional Maggiore wells are approximately 26 miles southwest of Deadhorse at these locations: Maggiore No. 2: T. 08 N., R. 11 E., Umiat Meridian; Latitude: 70o 03’ 54”N. Longitude: 149o 21’ 22” W. and Maggiore No. 3: T. 08 N., R. 11 E., Umiat Meridian; Latitude: 70o 04’ 20” N. Longitude: 149o 27’ 00” W.
Rock Flour No. 2, the first well Eni drilled this winter, is in the northernmost Rock Flour lease, ADL 390695. Heading southwest from MP1 it’s about two miles to Rock Flour No. 2.
The second well drilled, Rock Flour No. 3, is on ADL 389118 and was the farthest south well that Eni proposed to drill in the Rock Flour prospect, as per the plan of operations the company filed with the division last fall. The ice road splits about one mile south of MP1. It’s another nine miles south to Rock Flour No. 3
Between Rock Flour wells No. 2 and 3 on ADL 390696 was the location for another well, Rock Flour No. 4. A map included with Eni’s Feb. 9 request said the company no longer intends to drill that well.
Maggiore No. 1, the third well drilled this season, is approximately 15 miles south of Rock Flour No. 3 on ADL 390660. (Between Rock Flour and Maggiore are leases owned by other companies, including Chevron and Pioneer.)
The two additional wells Eni hopes to drill this season are five miles-plus north and west of Maggiore No. 1.
Authorized to do so by law, the division set the public notice comment period for the two additional Maggiore wells at 21 vs. 30 days.
