BlueCrest Alaska Operating LLC told the Alaska Department of Natural Resources, Division of Oil and Gas, in its fifth plan of development for the Cosmopolitan unit that it has begun drilling what it calls fish bone wells at the unit.

The multilateral design of these wells essentially does fracking as a function of well drilling, the company said.

The company drilled the first fish bone, the H12 well, this year, under its fourth plan of development covering the 2018 calendar year. The H12 consists of a wellbore with a long horizontal tail with seven vertical laterals rising up into the producing formation.

BlueCrest said with the fish bone well design it can more efficiently drill to the outer reaches of the reservoir.

The H12 fish bone well is in production and BlueCrest said that based on evaluation of that well, the company decided to re-drill the H16 well in a similar fashion, with eight laterals. BlueCrest said in its Oct. 6 plan submittal that the H16 was scheduled to spud Oct. 7.

Fifth POD

The fifth plan of development covers the 2019 calendar year.

BlueCrest said it is submitting applications to drill another fish bone well at the beginning of the year. This new well, the H4, is expected to be some 3,200 feet south of existing wells and “will begin to test the southern extent of our reservoir.” The H4, also in the fish bone design, will contain eight laterals.

After evaluating results of the H16a (the re-drill) and H4 fish bone wells, BlueCrest said it “will decide the best possible location for a possible second well in the 2019 drilling program. This well is currently anticipated to be the H11 Fish Bone Well that would step out to the north to evaluate the northern portion of the reservoir.”

Cosmopolitan

The Cosmopolitan unit encompasses four state oil and gas leases off the coast of the Kenai Peninsula at Anchor Point. BlueCrest became operator in 2014 after holding a 75 percent interest since 2011 with Buccaneer Energy as operator.

Production from the field began in April 2016 from an exploration well with oil trucked to the Nikiski refinery from the field.

BlueCrest brought in a new rig to directionally drill extended reach wells from an onshore drill site, where field production facilities are located. That new powerful well began drilling in early 2017.
