Rig capacity planning for PT Mantap Siak (MS) and PT Mantap Kampar (MK) drilling campaign

The background of this paper started from a massive MS and MK drilling campaign challenge in order to achieve contingent resources (2 C) and accelerate oil recovery. Besides that, those 2 (two) company are different entities with 384 km distance and heavy road terrain. Because of those challenges, required optimum rig capacity calculation and its scenario (use single rig/ without any replacement in completion phase or use double rig/ doing rig replacement in completion phase). To ensure rig calculation capacity has been aligned with field conditions and cost efficiency principle, calculations was described both in technical and cost aspect. In technical aspect, there will be explained horsepower calculation based on well configuration. In cost aspect, there will be explained total cost comparison between usage of a single rig (drilling rig only) and a double rig (drilling & completion rig). Based on technical and cost calculation, concluded that the optimum rig capacity for doing drilling campaign is 427 HP with single rig usage (without rig replacement). Those things supported by ±3.9 billion rupiahs cost-efficiency or 16% lower than double rig usage (using rig replacement for completion phase), and significant operation advantages by reducing duplicated work.
