Robust co-activities management is one key to combine continuous production and development in upstream operation. In the context of Mahakam Block, green and brown field developments are continuously adding portfolio, simultaneously with routine production activities. Huge volume of simultaneous operation in Mahakam could be seen in 2013 operation, with more than 20 million manhours, 6 Jack up Rigs, 5 Swamp Barge Rigs, 36 Well Intervention barges, 22 Construction Barges were managed. This paper will describe specifity of simultaneous operation in Mahakam Block, and presenting improvement efforts to maintain operation excellence of simultaneous activities in offshore and swamp in the past 3 years.
Simultaneous operations in Mahakam are applicable in the field of production with drilling, well intervention, and construction / project. The improvement efforts went through mapping, gap analysis, workshop, and validation. Organization improvement efforts were including standard guideline to determine work criticality using quantitative approach, introduction of routine coactivity matrix and recurrent activities sheets. The guideline has successfully helping harmonization among operation sites and all stakeholders. Reinforcement of audit is another aspect contributing to overall excellence of TEPI safety and production performance in 2016.
