05/05/2006

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

Drill through 200 feet of depleted sands, add a casing point and reach the pay target (measured depth between 11,000 to 13,000 feet) with adequate hole size while maintaining the smallest upper wellbore possible.

As the oil and gas industry has matured, three broadreaching and long-standing issues that affect virtually every well have assumed heightened importance: conservation of hole size, hydraulic isolation of selected zones, and maximization of well life. All of these issues involve one of the...

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...

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.

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...

A major east coast Operator needed to cover and isolate two sets of perforations in the base casing. An ESeal Liner was chosen because three previous liners were performing successfully in the same area for this Operator. The perforations needed to be sealed so water influx could be stopped to...

A major Alaskan Operator’s 22-year-old well had decreased production levels, had casing integrity issues, and was now producing too much water. An economical yet effective solution was needed that would not only permanently isolate the water-producing perforations in the production liner but...

An Operator drilling a well in the Permian Basin needed a solution to isolate losses below their intermediate 9-5/8 in. casing string that was causing them to lose mud at a rate of 60 Bbls/hr., and achieve the required mud weight to drill the curve/lateral section of the well. After setting...
