Buckskin is on Keathley Canyon blocks 785, 828, 829, 830, 871, and 872 in about 6,800 ft (2,073 m) of water. The initial phase consists of two wells on Keathley Canyon block 829 and a 6-mi (10-km) subsea tieback to the Lucius platform at Keathley Canyon block 875.
Drilling and completion of the initial two wells, which were drilled to about 29,000 ft (8,839 m), occurred in 2018. Installation of subsea facilities to complete the tieback occurred in 2019. The drilling, completion, and subsea installation were completed ahead of schedule and on budget, LLOG said.
The phase one production rate is expected to reach 30,000 gross b/d of oil. Additional phases of development will be required to fully develop the field, which is estimated to contain nearly 5 Bbbl of oil in place.
