Total turns to subsea separation for problematic Pazflor crude

摘要

Total has launched its third stand-alone development in Angolan deepwater block 17. Pazflor will combine production from one Oligocene and three Upper Miocene fields on the block's edge, spanning a total area of 600 sq km (232 sq mi). like its forerunners Girassol and Dalia, this project extends the boundaries of subsea technology. Its foremost innovation, and main element of risk, is its seabed gas/liquid separation system, the first in the world to be applied from field start-up. Pazflor, around 150 km (93 mi) offshore Angola, comprises the elongated Miocene structures Hortensia, Perpetua, and Zinia, and the compact Oligocene anticline, Acacia, nestling just to the south of Hortensia. All were discovered during 2000-03, with Acacia and Perpetua undergoing further appraisal during 2004-07. Water depths vary from 600 m (1,968 ft) on Zinia in the east to 1,200 m (3,937 ft) on Acacia.
