Shell Nigeria Exploration and Production Company (SNEPCo) accomplished the first remotely controlled well completion operation offshore Nigeria. The operation was carried out in the Bonga field, in a water depth of 1060 metres. The well-completion activity was carried out using a remotely operated controls system (ROCS) developed by Norwegian technology company Optime Subsea.
Optime Subsea's ROCS removes the requirement for both the umbilical, which before connected the surface to the seabed to regulate the tubing hanger in subsea well completions, and the topside hydraulic control unit.
The innovation additionally lowers financial resources, but it also significantly reduces the amount of deck area needed for these activities.
"We're really satisfied with the ROCS' performance. It implies that we can complete wells faster, at a cheaper cost, and with a far reduced CO2 footprint than traditional technologies," stated Justus Ngerebara, Lead Well Engineer at SNEPCo.
"The ability to free up valuable deck space immediately following the operation, by shipping the ROCS to shore, is a significant advantage for the rig operator," said Rodger Hooker, Chief Service Officer of Optime Subsea.
"We are overjoyed to bring this technology to Nigeria and extremely thankful for SNEPCo's innovative and ambitious approach to subsea well completion operations."
Last year, SNEPCo obtained its first ROCS from Optime Subsea and has been collaborating closely with them to incorporate the technology into their operations. Optime Subsea had previously undertaken ROCS operations in the North Sea and Gulf of Mexico, although this was their first in African waters. The operation was led by Optime Subsea's Nigerian business, with assistance from the company's headquarters in Norway.
According to the company, employing ROCS allows operators to eliminate around 50 tonnes of equipment from their offshore transportation list, resulting in decreased CO2 emissions. In addition, it minimises operating length and HSE threat on the drill floor. This technique lowers CAPEX and OPEX for operators.
