HOUSTON – Castex Offshore Inc. has started drilling on the Main Pass Block 270 #3 well in the Gulf of Mexico, according to partner Petsec Energy.
The exploratory well is being drilled in federal offshore waters on Petsec’s Hummer prospect, located around 50 mi (80 km) southeast of Venice, Louisiana, in about 215 ft (65 m) of water.
The well is being drilled to a true vertical depth of 16,000 ft (4,876 m) to test Miocene age sand objectives. The Main Pass 270 #3 well is being drilled using the Ensco 87 jackup and is expected to take approximately 60 days to reach total depth.
Petsec has a 12.5% non-operating working interest (10.24% net revenue interest) in the well. The company’s share of drilling costs is estimated to be $2 million net. Other private companies hold the remaining 87.5%.
