Expandable-tubular technology involves a process that expands casing in oil wells drilled in especially challenging environments, such as deepwater. Until now, operators have had to use progressively smallerdiameter pipe as a well was drilled deeper; but expandable-tubular goods are designed for...
ESeal™ HP Patch systems: A high-performance wellbore repair solution.
These systems utilize a higher yield-strength material than standard ESeal systems. The material’s increased burst and collapse ratings provide enhanced performance and reliability.
From re-completions to field...
The ESeal Flex expandable system is an expandable solution primarily designed for well completions, stimulations, and workovers.
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.
The challenge was to cover and isolate a hole in the vertical section of a horizontal well to continue with the planned high-pressure 14-stage fracturing program.
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.
Enventure’s ESeal™ casing patch solutions provide a robust, permanent alternative to unreliable cement squeezes while maximizing ID and maintain the largest production conduit possible. ESeal casing patches are effective solutions for addressing multiple casing integrity issues.
