05/05/2006

Get back on planned drilling program and finish the well with an adequate hole size to evaluate potential production zones at TD.

01/03/2009

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.

Two challenges facing operators as the energy industry moves into the next century are accessing of new reservoirs that currently cannot be reached economically and maintaining profitable production from older fields. Recent advances in one of the oldest and most fundamental areas of exploration...

Expandable-tubular technology involves a process that expands casing in oil wells drilled in especially challenging environments, such as deepwater. Until now, operators have had to use progressively smallerdiameter pipe as a well was drilled deeper; but expandable-tubular goods are designed for...

Save the wellbore by installing a SET® 7-5/8" x 9-5/8" 53.5# Openhole Liner over a 420.86 ft (128.28m) interval to isolate the weak section.

  • 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®...
