ABSTRACT
Extended Reach Drilling (ERD) already carries a well understood list of technical challenges that if not adequately
addressed can easily result in failure to complete the well. In a fast track deepwater development the complexities
and risk exposure for any operating company are further increased. Many of the deepwater ERD challenges
encountered by Tullow Ghana Ltd are touched on in this presentation and three are discussed in some detail,
namely; hole cleaning, borehole stability and well bore surveying. The latter subject is also covered by the
presenter and others in a separate SPE paper. The presenter does not try to gloss over the difficulties
encountered during the execution phase but instead uses these as examples to demonstrate learning points and
highlight the importance of engineering to reduce risk and maximise the probability of success. The responsibility
carried by Engineers is therefore one of the key themes of this presentation and is a message the presenter felt
appropriate to stress to an attentive audience of new Engineers in the emerging oil province of Ghana. The
presentation finishes on a high note by demonstrating that despite the ERD operational difficulties encountered
the field was delivered on target with ‘best in class’ deepwater drilling performance.
