Well Information
Operator: Chevron
Location: Vermilion 31
Challenge
The Operator wanted to seal a leaking packer in an offshore production well without the use of a rig, due to availability and pricing. Engineering wanted a fluid that would fall through seawater in the vertical 7 X 3 ½”annulus. The fluid required an extended set time, so it would maintain its properties and form an effective seal.
Solution
Liquid Bridge Plug®
A special formulation of Liquid Bridge Plug® was designed with additional density to increase the settling rate. After mixing 168 gallons of Liquid Bridge Plug®, the resin sealant was loaded into the annulus and chased with 9 bbls of seawater.
The well was shut in and for 14 hours the resin sealant fell through the seawater and settled on top of the leaking packer.
Results
After a 24 hour cure time the Liquid Bridge Plug® was tested to 1,000 psi for 30 minutes with no recorded pressure losses.
The Operator was pleased with the total operation and that a rig-less operation had been performed that saved thousands of dollars in rig time not to mention any lost production waiting on a rig.
