It is well established that working in an integrated team is a more valuable and efficient way of working. But how to ensure that the maximum value is harnessed from those multidisciplinary teams? The approach chosen in Shell Malaysia is to turn the typical sequential study flow pattern from seismicstatic-dynamic-development plan into a truly parallel one. This means: integration through iterations, where the end objective is worked from a 50/50 solution iteratively towards the 80/20 or more. This is what 3D-All-The-Way™ is all about! This paper describes a live example of this way of working applied to the further development of F6, one of the largest gas fields operated by Shell Malaysia in Sarawak waters.
The F6 field is located in the Central Laconia carbonate province, some 180 km offshore form Bintulu. The field has been on production since 1987, and over half of the reserves produced have been drained by 11 slightly deviated wells from its own standalone platform facilities. F6 existing well capacity is coming under threat with regional aquifer rise and localised coning around wells. As a result, further development is required to maintain the capacity at the level required from the supply plan, and to ensure that reserves are protected against the un-even rise of the aquifer in the field. This redevelopment study used the most recent data available, ranging from 3D seismic, to pressure and contact surveillance.
The business value of the 3D-All-The-Way™ approach is (1) speed: as the redevelopment plan and supporting studies are executed in a reduced time-frame (2) efficiency: as from an early stage and continuously through the study work unrealistic subsurface realisations and development options are screened out, (3) quality: the overall robustness of the subsurface work is improved, as every discipline are contributing simultaneously, and at each iteration. Finally, as an added bonus, the teamwork is more enjoyable and crossdiscipline learning is enhanced.
The methodology followed by the F6 further development team is being applied to other Field Development Plans within Shell Malaysia E&P, with the same success, saving time, improving the quality of the models and of the decisions.
