Glacier drilling on west side
Company is looking at resuming development and exploration activities at Cook Inlet West McArthur River and Redoubt units
For Petroleum News
Glacier Oil & Gas Corp. has been focusing on its west side properties lately.
While the independent recently announced plans for a series of “small ball” projects at its North Fork unit for the near-term, it has undertaken a major optimization program at the West McArthur River unit and is planning considerable activities at the nearby Redoubt unit.
The West McArthur River program included a major effort to shift processing of oil from the unit to the Kustatan Production Facility, away from the aging West McArthur River Production Facility. It also included a four-well workover program across the unit.
The company swapped out jet pumps for electric submersible pumps at the WMRU No. 2B, WMRU No. 5, WMRU No. 6 and Sword wells, which reduced the need for power fluid. The company also perforated additional zones in WMRU No. 2B and WMRU No. 5. The workover program added “significant” production, according to Glacier.
This year, as previously reported, Glacier is planning to resume exploration activities at the unit by using the Spartan 151 jack-up rig to drill the long-delayed Sabre well.
West McArthur River produced 365,057 barrels of oil and 159.4 billion cubic feet of natural gas in 2016, according to Glacier. Those totals yield monthly averages of 30,421 barrels of oil and 13.2 billion cubic feet of natural gas. Actual monthly oil production ranged from a high of 34,717 barrels in January 2016 to a low of 23,048 barrels in September 2016. Actual monthly natural gas production ranged from a high of 20.6 billion cubic feet in December 2016 to a low of 6.3 bcf in September 2016.
The unit has five producing wells, five shut-in wells and one class I disposal well.
RedoubtGlacier recently completed a similar program at the Redoubt unit.
The company upgraded the Osprey platform, swapping out a gas-fired boiler with an electric heating system that uses excess power from the Kustatan Production Facility.
Glacier drilled the RU No. 7B sidetrack of the RU 7A well and conducted hydraulic fracture stimulation of the sidetrack. The company is “waiting for definitive results and data received as a result of the RU 78 sidetrack and stimulation operation to determine the best path forward.” In the near term, those plans could include replacing electric submersible pumps at the RU No. 1A, RU No. 5B and RU No. 9 wells and sidetracks.
Over the coming year, Glacier plans to sidetrack and hydraulically fracture the RU No. 3 well for use as an injection well to improve production. The company is reviewing its waterflood program to determine if it should convert non-producing wells to injection.
Longer term, Glacier wants to begin a delineation program in the Central, Southern and Northern fault blocks. And, “when favorable economic conditions warrant,” the company is considering an exploration program for areas north of the Northern fault block.
The Redoubt unit produced 232,301 barrels of oil and 53.1 bcf of natural gas in 2016, according to the company. Those totals yield monthly averages of 19,358 barrels of oil and 4.4 bcf of natural gas. Actual monthly oil production ranged from a high of 20,460 barrels in August 2016 to a low of 18,168 barrels in February 2016. Actual monthly natural gas production ranged from a high of 4.7 bcf in August 2016 to a low of 4.1 bcf in April 2016. The unit has two producing wells, five shut-in wells, one injection well and one disposal well.
