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...

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...

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...

The in-situ permanent expansion of casing and tubing in oil and gas wells is now possible. This landmark advancement in well completion technology and repair can decrease the cost of initial well completion, make completions in difficult formations possible, and can salvage damaged completions...

Loss of wells and / or production due to significant casing damage caused by formation subsidence can be a costly problem, particularly in shallow high porosity reservoirs. Solid Expandable Tubular (SET) Cased-hole Liners (CHL) is one method being utilized to overcome damage to casing due to...

In recent years, many operators in the oil and gas industry have moved to horizontal drilling, a process that has proven much easier than trying to move hydrocarbons into vertical wellbores. For the last several years, a major Middle East operator has been leveraging horizontal drilling...

For years operators have been forced to set drilling liners prematurely due to downhole conditions such as lost circulation and abnormally pressured formations. The conventional solutions for running unplanned casing strings have prevented some operators from reaching the well’s projected target...
