Successful catenary coiled tubing operation in Nigeria

Challenge

• 8 wells, all shut-in, located on a platform with insufficient deck space and crane capacity to install equipment
• Tight budget to try to bring those wells back online

Solution

• Halliburton proposed the use of coiled tubing catenary system with a 1.75" pipe and a 125K spread along with Halliburton special completion tools and fluids
• Close collaboration with customer to perform detailed diagnostic on each well, customized designs and integrated multi-PSL program execution plan

Result

• Coiled tubing catenary system enabled a variety of well intervention capabilities to restore production on those wells such as mechanical isolation, perforations, cement isolation, milling and scale removal
• Project cost was significantly lower than a similar scope with a rig
• From 8 shut-in well, 6,450 bopd were added to the production in this mature field
