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...

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...

SET technology is the result of a cold-working process that permanently deforms the pipe without any additional heat. The procedure inherent to expanding tubulars takes the steel beyond its elastic limit into the plastic region of the stress-strain curve, while remaining safely below ultimate...

A major Middle East Operator experienced problems running expandable liners to isolate a zone of total loss circulation and tight spots, increasing the risk of stuck pipe.  The addition of Expandable Bow-Spring Centralizers provided the solution with pre and post-expansion stand-off that allowed...

Enventure, a leader in expandable technologies, developed the ESET™ system, the industry's only solid expandable liner that can be rotated and reciprocated to help operators meet their objectives, reduce non-productive time (NPT) and elevate the value of high-cost assets.

A major operator in the Norwegian North Sea anticipated problems while drilling a    12-¼ x 13-½ in. hole section which required setting 10-¾ in. casing early. This left a section of overburden exposed above the reservoir. 

The 8-5/8 in. ESET HP System isolated the overburden section,...

An Operator in the Norwegian North Sea encountered a restriction 118m (387 ft.) off bottom while running a 10-¾” MLT liner. This was the third attempt to pass the trouble spot. The decision was made to cement the MLT liner in place and find an alternative way to cover up the troublesome Balder...
