Regain pressure integrity of the 7-3/4 in. production liner for stacked FracPac™ completion operations using Solid Expandable Tubular (SET™) technology.

09/12/2004

Solid expandable tubular technology presents an opportunity to significantly boost the production capacity of wells by increasing the size of the completion. As such, it offers an economically attractive and environmentally friendly option to breathe new life into gas fields. It is flexible in...

During initial completion operations on a deepwater subsea oil well in the Gulf of Mexico, the 7-3/4 in., 46.1 lb/ft casing failed the pressure test in the production liner. Subsequent operations located the casing leak 1,800 ft above the target completion intervals. The original completion was...

Implement an ESeal solution that would enable targeted completion with packer seats while also repairing the damaged vertical section of casing in the Barnett.

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...

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.

A large independent Operator discovered several leaks and a parted section in the 7 in. production casing from 2,000 ft. to 500 ft. In order to fracture the well, casing integrity had to be restored to handle over 6,000 psi surface fracture pressure to ensure the well could become a viable asset...

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...

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...
