Well Integrity Resources

Production casing leaks are a frequent problem in mature oil fields, particularly where there is corrosion. Wells with casing leaks usually do not meet well operating criteria so they must be shutin, causing a loss in valuable production. Casing leaks normally require a rig workover to repair since the tubing often has to be removed. Rig workovers are very expensive in offshore loions ...

Wellbore stability predictive models may also be used to design appropriate completions for inflow problems where hole collapse and associated sand production are concerned. For example, in highly permeable and weakly cemented sandstones, such predictive tools can be used to decide whether a slotted or perforated liner completion would be preferred over leaving a horizontal well completely ...

· This is very similar to digging a hole in the sand on the beach, the faster you dig the faster the hole collapses. It happens in a wellbore when little or no filter cake is present. The unbonded formation (sand, gravel, small river bed boulders, etc.) cannot be supported by hydrostatic overbalance as the fluid simply flows into the formation. Sand or gravel then falls into the hole and causes ...
