Japan Oil Development Company (JODCO) has been operating several offshore oil fields jointly with Abu Dhabi National Oil Corporation (ADNOC) in the U.A.E. since the 1970's. A lot of new drilling technologies have been introduced to contribute in assisting maximize economic oil recovery through innovative horizontal hole drilling techniques and to rectify drilling problems such as shale instability and well integrity issues. This paper describes the progress of horizontal drilling technique including multi-laterals tie-back system and casing window opening technology, operation guidelines for shale instability problem based on chemical and mechanical analysis, and applications related to well integrity security. In addition, approaches for the integrated drilling program and the objective evaluation of drilling performance are briefly introduced.
