COVINGTON, Louisiana – LLOG Exploration Co. has issued an update on its development projects and recent discoveries in the deepwater Gulf of Mexico.
In June, the two-wellCrown & Anchor development began production in Viosca Knoll blocks 959, 960, 1003, and 1004. The wells are tied back to the Anadarko-operated Marlin facility in Viosca Knoll block 915 and are producing at a combined gross rate of more than 10,000 boe/d.
LLOG’s partners in Crown & Anchor are Beacon Offshore Energy Operating LLC and Ridgewood Energy.
Last year LLOG made the Khaleesi and Mormont discoveries in about 3,900 ft (1,189 m) of water in Green Canyon blocks 345, 389, 390, 434, and 478. Each of the two discoveries has been delineated by two wells and a side track that discovered multiple oil-bearing Miocene horizons. Given the upside potential of the discoveries, the company said that it is evaluating the need for a new floating production system to co-develop the fields. LLOG’s partners in Khaleesi and Mormont are Ridgewood Energy, Red Willow Offshore, LLC, CL&F Offshore, LLC, and Houston Energy.
At theBuckskin project in Keathley Canyon blocks 785, 828, 829, 830, 871 and 872, the Seadrill drillship West Neptune has drilled the two development wells. Installation of subsea facilities will commence soon, and first production from the field is expected in mid-2019.
To fully develop the field, which is estimated to contain nearly 5 Bbbl of oil in place, additional wells and subsea facilities will be required after the initial phase. The company’s partners are Repsol E&P USA Inc, Beacon Offshore Energy Buckskin LLC, Navitas Petroleum LP, and Ridgewood Energy.
LLOG and its partners have sanctioned the Stonefly development in Viosca Knoll block 999. The company drilled two wells at Stonefly including the discovery well in 2016 and a follow up well in 2017, both of which encountered oil-bearing sands in the Middle Miocene. Subsea tieback for the two wells to the nearby Talos Energy-operated Ram Powell platform is being planned with estimated first production around December 2019. Its partners in Stonefly are Beacon Offshore Energy Operating LLC, Houston Energy, Red Willow Offshore, LLC and Ridgewood Energy.
At theWho Dat field in Mississippi Canyon block 503 a subsea pump installation project has been approved by LLOG and its partner, Deepwater Development Co., to optimize reserves and accelerate production. Installation of the subsea pump is expected to be completed in the second half of 2019 and to result in an increase in production rate of 3,000 b/d of oil and an increase in proved reserves of 7-10 MMboe.
In addition, four LLOG-operated discoveries (six wells) that are under development and are expected to be placed on production in 2018.
The LaFemme prospect in Mississippi Canyon block 427 was discovered in mid-2016 and was successfully appraised by a follow up well in late 2016. The Blue Wing Olive prospect in Mississippi Canyon blocks 427-471 was drilled in late 2016 with a discovery well encountering two oil and natural gas reservoirs in the Miocene. The Red Zinger prospect in Mississippi Canyon 257 was drilled in 2016 and found multiple Miocene targets.
LaFemme, Blue Wing Olive, and the Red Zinger wells are being tied back to the LLOG-operated Delta House facility in Mississippi Canyon block 254. LLOG’s partners in LaFemme and Blue Wing Olive are Beacon Offshore Energy Operating, LLC, Red Willow Offshore, LLC, Ridgewood Energy, and Houston Energy. The company’s partners in Red Zinger are Beacon Offshore Energy Operating, LLC, Red Willow Offshore, LLC, and Ridgewood Energy.
The Claiborne prospect in Mississippi Canyon block 794 had a discovery well drilled in 2015 and was successfully appraised with a second well in late 2016. Both wells are being tied back to the Walter-operated Coelacanth platform in Ewing Bank block 834. Its partners are Ridgewood Energy, Red Willow Offshore, LLC, and CL&F Offshore LLC, and Beacon Offshore Energy Operating, LLC.
