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. SHORT BIO Fraser Lawson has over 25 years of international well engineering experience including various ERD and deepwater projects. He holds BSc (hons) and MSc degrees in Civil and Petroleum Engineering and is a Chartered Engineer. He currently works as the Well Engineering Supervisor for Tullow Ghana Ltd
