Shell said the facility set a water depth record for a drilling and production facility.
The facility will handle production from Great White, Silvertip, and Tobago fields. Designed capacity of the facility is 100,000 bo/d and 200 MMscfd of gas.
Shell said that production from Great White is the first from the gulf’s Lower Tertiary section. So far the company has drilled six development wells in Great White of which five are producing wells and one is an injection well. Shell notes that it may need as many as 35 wells to develop the three fields.
Perdido is the first spar with direct vertical access wells, Shell said. Besides these wells, the development will also require remote subsea completed wells.
Because of the low pressure and temperature of the fields, Shell has installed an innovative subsea separation and boosting system that can lower back pressure on the wells by about 2,000 psi.
