  • 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®...

A major operator was sidetracking out of an existing well to a nearby reservoir.The first attempt to sidetrack utilizing a conventional casing design failed to reach the target depth and damaged the 13-3/8 in. casing.

The casing design for a...

An major operator received one of the first post-Macondo permits to continue drilling an exploratory well in the deepwater Gulf of Mexico using subsea BOP's.

The operator needed to achieve zonal isolation across shallow hydrocarbon-bearing sands and to reduce ECD's during cementing...

Challenge: Redevelop an established Gulf of Mexico deepwater field by accessing additional reserves.

09/01/2011

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. 

03/13/2012
An operator drilling a sub-salt exploration deepwater well in Gulf of Mexico, experienced an unstable wellbore at the base of the salt; which resulted in setting the 9-7/8 in. liner 3,400 ft higher than originally planned.
In exploratory wells, maintaining hole size is critical due...
