In order to facilitate a lower zone fracture treatment, three sets of perforations required a high-pressure, gas-tight isolation treatment that would maximize casing ID for completion tools. The solution provided a successful, gas-tight isolation of the three sets of perforations...

For years, the reduction of tubular inside diameter (ID), or “telescoping effect,” limited the exploration and production of oil and gas. Using conventional technology, operators faced significant loss of ID in the course of the normal drilling process, during reentry and deepening of existing...

An operator in the northern Colorado, Piceance basin discovered a part in 4-1/2 in. base casing. The casing split meant they would not be able to complete the lower six stages of the well. The operator initially used conventional methods in an effort to repair the damaged casing to recover the...

The Operator had two sections of perforations in 4-1/2 in. casing that needed to be repaired. They required a solution that would repair the 4-1/2 in. casing and still maintain sufficient ID for this well to be used as a power water injector well.

In the Marcellus Shale, fracturing rates and pressures can be substantial, but there are other problems also associated with completing these wells, which can promote casing failure or compromise the pressureintegrity of a well. A...

In the first stage of the fracturing program, the uppermost fracture sleeve failed - leaving the economic viability of the wells at risk.

An Operator, in the Ardmore Basin, was unable to put a well onto first production due to casing damage at a 5½” to 4½” casing crossover.

A major Operator in the Anadarko Basin of Oklahoma lost pressure integrity during completion / frac operation.  A 3-1/2" ESeal HP Liner straddled the parted packer, restoring pressure integrity, and enabling the Operator to continue their completion / frac operations

An Operator in the Permian Basin of West Texas had completed seven stages of their hydraulic fracturing program when they encountered a leaking connection at 16,380 ft. MD and a damaged casing joint at 16,300 ft. MD. The Operator needed a reliable solution that would cover up...
