Production casing
Production casing is used to isolate production zones and contain formation pressures in the event of a tubing leak. It may also be exposed to:
Injection pressures from fracture jobs
Downcasing, gas lift
The injection of inhibitor oil
A good primary cement job is very critical for this string.
Production casing
It can be set above the production zone or run through it. The main function is to isolate the production zone from the other forms such as water bearing sands. This type of casing is also used as a conduit for production tubing.
– Significant cost reduction due to shorter strings
– Drill pipe is used to run the liner which leads to less rig time
– Liner can be rotated while cementing the hole which can improve the quality of cement.
