Title: Drilling extended-reach/high-angle wells through overpressured shale formation

Abstract

This paper discusses Amoco U.K. Exploration Co.'s unsuccessfully attempts to drill an extended-reach well in Arbroath field (U.K. Block 22/17) and how problems encountered were resolved on subsequent high-angle and extended-reach drilling operations in the field. The resolution of these problems over the course of drilling four high-angle wells and one extended-reach well involved (1) determining mud weight by use of rock mechanics principles, (2) evaluating hole conditions with a wellsite torque-and-drag program, (3) optimizing BHA performance, and (4) developing techniques for effective high-angle hole cleaning. By use of the methods outlined in this paper, improved drilling performance and significant cost savings are demonstrated.
