Shell, Talisman, BP, Venture, DONG, EnCana

Since its launch in April 2003 The Drift Catcher™ has become a preferred method for many operators because of its safety, reliability and the certainty it provides on successful drifting.

December 03 -January 04

IBT™ put to the test on 19,200 foot of 12¼" ERD

Run:EnCana 5" TFA Bypass IBT™ - Scott Platform

Over a period of 7 weeks three IBT™ tools were used and reused with 100% reliability in order to achieve successful completion of the longest ever 12¼" ERD section in this field.

Exxon-Mobil with world first uses of two multi-bypass tools.

A 4 ¾" IBT™ was used in conjunction with a 6 ½" weight set bypass tool to clean out the 4 ½" x 7" x 9 5/8" Beryl Alpha Well. The IBT™ allowed the 3 ½" x 7" annulus to be cleaned at 600gpm!

April 2003

Britannia platform uses IBT™ for second cleanout.

The ConocoPhillips Chevron-Texaco platform achieve second consecutive 7in liner cleanout with the IBT™. The cased hole was LWD logged and the bottom tagged for the correlation of the PCT perforation. Then the IBT™ allowed them to clean up at 1000gpm.

Exxon-Mobil shows IBT™ saves you ECD.

The Beryl Alpha team used the same 4 ¾" IBT™ to clean up the high angle 3 ½" x 9 5/8" annulus on three consecutive 6" drilling assemblies. The PWD showed that the ECD was LESS in bypass at 400gpm than, 250gpm without bypass!

Feb 2003

Talisman proves IBT™ good for High Temp.

Talisman energy used the IBT™ successfully in a high temperature well on the Clyde Platform early this year. The tool worked repeatedly at temperatures of 320 Deg F (160 Deg C).
