SNEPCo conducts remotely controlled well completion at Bonga 78

Optime Subsea's ROCS eliminates the need for both the umbilical, which traditionally connects the surface to the seabed for controlling the tubing hanger in subsea well completions, and the topside hydraulic control unit. This innovation not only cuts costs but also significantly reduces the amount of deck space required for these operations.

“We are very pleased with the performance of the ROCS. It means that we can perform well completion operations quicker, at lower cost, and with substantially lower CO₂-footprint compared to conventional systems,” says Justus Ngerebara. Lead Well Engineer at SNEPCo.

Last year, SNEPCo took delivery of its first ROCS from Optime Subsea and have worked closely with Optime Subsea to integrate the system into its operations.

Using a ROCS means that operators can cut approximately 50 t of equipment from their offshore transportation list, which means substantially lower CO₂-footprint. It also means reduced operating time and less HSE exposure on the drill floor. In total, it reduces both CAPEX and OPEX for operators.

Optime Subsea has performed multiple ROCS operations in the North Sea and Gulf of Mexico, but this was the first in African waters. The operation was led by Optime Subsea’s operation in Nigeria, supported by personnel from the company’s headquarter in Norway.

“To be able to free up valuable deck space immediately after the operation, through shipping the ROCS to shore, is a significant advantage for the rig operator. We are delighted to bring this technology to Nigeria and very grateful for SNEPCo’s innovative and ambitious approach to subsea well completion operations,” says Rodger Hooker, Chief Service Officer at Optime Subsea.
