Use catenary coiled tubing to perform diagnostics and execution plan
REGION - NIGERIA
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
