Two challenges facing operators as the energy industry moves into the next century are accessing of new reservoirs that currently cannot be reached economically and maintaining profitable production from older fields. Recent advances in one of the oldest and most fundamental areas of exploration...
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...
- Operator was experiencing trouble formation caused by narrow pore pressure/fracture gradient window which caused casing to be set higher than planned.
- Operator decided that expandables were the way to go.
- All of the customer's operating objectives were met.
The customer was sidetracking the well, and unable to run their 16-inch liner. The 13-5/8 inch and 11-3/4 inch casing were both set high, which would compromise the originally planned 8-1/2 inch hole size.
The operator selected a 9-5/8 x 11-3/4 in. SET®...
By ensuring optimal hole size, well designs using solid expandable tubulars have a far-reaching effect on drilling, evaluation, completion and life-of-well solutions. Enventure Global Technology's Kevin Waddell, Jerry Fritsch and Kristaq Mitrushi discuss the growing influence of solid...
Install a 13-3/8 x 16 in. 97.0 lb/ft openhole solid expandable tubular (SET®) system to extend the 16 in. casing section past the trouble zone—preserving the set point for the following 13-3/8 in. standard casing and enabling successful execution of the well plan.
While drilling an exploration well, an Operator encountered a narrow pore pressure/fracture gradient window that required using more casing strings than planned.
Enventure’s process for running SET systems through window exits accommodates vertical, highly deviated, and horizontal wellbores (including extended reach wellbores).
Enventure, a leader in expandable technologies, developed the ESET™ system, the industry's only solid expandable liner that can be rotated and reciprocated to help operators meet their objectives, reduce non-productive time (NPT) and elevate the value of high-cost assets.
