Get back on planned drilling program and finish the well with an adequate hole size to evaluate potential production zones at TD.

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...

Optimizing the casing program is one of the most critical factors in well design for deepwater applications. Conventional design often dictates that very large surface casing be used to allow passage of a high number of subsequent casing strings telescoping down in size that are required to...

Establishing and maintaining hydraulic integrity between liner hangers and the base casing in which they are set has long been one of the most problematic areas facing operators. With failure rates on pressure seals in overlaps now exceeding 40% in some regions, the need for a solution to this...

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 major operator received one of the first post-Macondo permits to continue drilling an exploratory well in the deepwater Gulf of Mexico using subsea BOP's.

The operator needed to achieve zonal isolation across shallow hydrocarbon-bearing sands and to reduce ECD's during cementing...

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.

Making Enventure's Solid Expandables a part of the drilling plan enabled deep-water operators in the Mississippi Canyon to cut their previous drilling time from 140 days to just 48.  Installing over 2700 feet of Solid Expandable liners running at depths up to 4100 feet allowed...
