Get back on planned drilling program and finish the well with an adequate hole size to evaluate potential production zones at TD.
Install a high-collapse SET® expandable liner to case off the trouble zone.
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.
- Operator was experiencing trouble formation caused by narrow pore pressure/fracture gradient window which caused casing to be set higher than planned.
- Operator decided that expandables were the way to go.
- All of the customer's operating objectives were met.
The customer was sidetracking the well, and unable to run their 16-inch liner. The 13-5/8 inch and 11-3/4 inch casing were both set high, which would compromise the originally planned 8-1/2 inch hole size.
The operator selected a 9-5/8 x 11-3/4 in. SET®...
In 2009, a global super-major operating out of Borneo experienced problems with a well it was running from a drillship in over 5,000 feet of water off of the Sarawakan coast. An initial exploration well working a straight hole in a shale formation, the operator encountered an unstable...
An operator needed to overcome drilling obstacles in their Gulf of Mexico, HPHT well.
Three SET® Systems were installed in this well and enabled the operator to reach the planned target.
