In order to facilitate a lower zone fracture treatment, three sets of perforations required a high-pressure, gas-tight isolation treatment that would maximize casing ID for completion tools. The solution provided a successful, gas-tight isolation of the three sets of perforations...


Isolate multiple zones while maximizing diameter by installing a SET Open-hole Liner with swellable elastomers. The maximum diameter would help reduce fluid friction during high-rate fracturing operations.


Accurately install SET® Openhole Clad solid expandable systems featuring water-sensitive swelling elastomer seals. The installation further proved SET® technology applied for the first time a year earlier in another field.



Install a 7-5/8 x 9-5/8 in. SET Openhole Liner (OHL) to isolate higher pressure zones so that mud weight could be reduced to combat lost circulation.


Expandable casing goes into the well in one diameter, then as an expansion mandrel is either drawn through or pushed through, it expands by as much as 300%. The technology was recently developed and tested in a slotted form. This technology and a new solid form are the subject of several...


Interesting results are emerging from the ongoing research of a novel advancement—expandable tubular technology. Studies on the effects of expansion on the mechanical properties of postexpansion casing, the resistance of expanded casing to sulfide stress cracking
and Hoop (tangential)...


Revolutionary expandable tubulars and connectors will change the basic design and construction of oil and gas wells. With these innovations, operators can reach reservoirs that are economically inaccessible with conventional technology.


In the ultra-deepwater Gulf of Mexico, formation conditions, and the great depth of exploration plays, combine to make some drilling targets unattainable, until now. This was the original problem facing Shell, when it developed expandable tubulars.


Deepwater and ultra-deepwater exploration and development is getting the bulk of offshore investment, but a well within the sight of land has tested a technology that may revolutionize well construction in all water depths.


Three long standing issues that affect virtually every well have continued to become more important: conservation of hole size, hydraulic isolation of selected zones and maximization of well life. All of these issues involve one of the industry's most fundamental technologies-wellbore tubulars...
