  • 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®...
