First well interventions by a full-catenary CT system on a DP vessel with compensated gangway

An offshore operator in Brunei faced the challenge of increasing the injectivity in waterflooded fields, to improve hydrocarbon production. The solution chosen to achieve the injection targets involved the use of a stimulation vessel with coiled tubing (CT), nitrogen and the pumping capability to perform well interventions. The operation faced challenging offshore weather conditions, limited platform access, a lack of crane facilities and an aging offshore infrastructure. It also had to provide an emergency disconnect system, while simultaneously improving operational efficiency.
