AbstractThis paper covers the drilling related optimizations which have been implemented during the first development phase of the Al Shaheen field offshore Qatar. The issues adressed include bit optimization, BHA enhancement and replacement of Class 'G' cement, which have led to an overall cost reduction of some 18% compared with the initial phase.
