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...

Enventure's 4-1/4 x 5-1/2 inch, 17 lb/ft ESeal Liner was installed in a Barnett Shale 3000 ft lateral wellbore to isolate existing perforations while allowing fracturing of new shale colume between old perforation clusters.

An operator's well in the Marcellus Shale developed a split in the horizontal section during the primary cement job. Pressure integrity needed to be restored before the operator could continue completing the well.

As part of a multi-well program, isolate severe water-thief zones in a field where squeezing, casing patches and dual packer isolation assemblies rarely worked. The solution increased production and ultimately resulted in higher reserves.

Isolate a low fracture-gradient zone to enable an optimal completion.

BP experienced losses while drilling a development well due to weak sand formation directly below the 13-3/8in. shoe. Multiple attempts were made to stem the losses - all without success.
A solution was required to isolate the weak sand formation and enable drilling to continue with higher...

The challenge was to set three multilateral windows at an optimum Total Vertical Depth (TVD) in the reservior.

This casing failure occurred during the 13th stage of the well’s plug-&- perf frac job of it’s 4,500 ft lateral section.  To avoid killing the well with potentially damaging weighted fluids, a rig assist snubbing unit was used to enable live-well operations including milling out the casing...

Results from two case histories in shale plays indicate that the use of an expandable refrac liner gives comparable, or better, gas production than other methods of perforation isolation, and provides assurance
for frac stage injectivity.

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...
