Home / News / 1st expandable installation with cement, underreaming completed

Enventure Global Technology has announced the successful completion of the first commercial well using its SET expandable system that eliminated cementing and underreaming operations. This milestone comes on top of the 21-day, $1 million per well savings established by incorporating expandable open-hole liners in a well slimming program, the company said in a release.

The company says that the key for success in the HPHT gas well in Robertson County near Franklin, Texas, was the use of a 6 x 7 5/8-in. SET system and swellable elastomer technology. This system utilized the swellables to provide zonal isolation of the approximately 1,000-ft drilling liner.

Although underreaming or hole enlargement is usually a requirement when running expandable systems, this liner did not require a cement job, therefore the hole size required could be minimized. The operator estimates an additional four to six days of rig time were saved by not having to complete the underreaming process.

According to Enventure, the operator’s lead engineer said the long-standing application of SET expandable technology has provided exponential savings over the last four years and 44 wells.

Enventure reports that it began incorporating 6 x 7-5/8 in. open-hole expandable systems in 2004 to enable slimmer well profiles while maximizing hole size at total depth in deep land gas wells.
