LONDON – The jackup Noble Percy Johns has spudded the Lidongo X Marine-101 (LXM-101) exploration well in the Marine XI block in the Congo basin, offshore Republic of Congo (Brazzaville), for SOCO.
LXM-1 well is designed to test the extension of an adjacent gas/condensate/oil field into the block. The well location is 23 km (14.3 mi) northwest of Pointe Noire in a water depth of around 45 m (147 ft).
Planned TD is 2,600 m (8,530 ft), but with the possibility to drill to 3,100 m (10,170 ft), terminating in the lowermost part of the Djeno sandstone formation. Drilling is expected to take 35 days to complete.
In Democratic Republic of Congo (Kinshasa) block V, a lake bed survey was completed last month over Lake Edward. SOCO and its partners will now process and interpret the data.
Offshore southern Vietnam in block 9-2, SOCO expects theNaga 2 rig to complete the CNV-7PST1 well on the Ca Ngu Vang (CNV) field next month.
The well has encountered unexpected geological problems in the hole just above the reservoir. Following borehole instability issues caused by a below-seismic-resolution fault in the Oligocene section (just above the Basement), the section must be redrilled and an alternative casing program employed to ensure the well can be drilled safely into the Basement.
Once onstream, the well is expected to lead to increased production from the CNV field.
