Moving Rig Time Efficiency to Improve Operations, Reduce Non-Productive Time Rig and Emission Co2 Using on Trailer

Abstract

One of the efforts achieve Key Performance Indicator is to realize efficient organizational performance. Optimizing rig movement management is needed in PT. Pertamina Hulu Indonesia Sangasanga Field by reducing the duration of moving between wells and ensuring that the Rig cycle time kept to minimum. In real condition, all equipment in rig unit is still arranged on its own Skid with a large number of transport loads and in the activity of moving Rig/Hoist equipment between wells, all equipment transported is moved and rearranged at the next well location by using Winch Truck, Truck Crane, Flatbed truck and Crane. Moving activities with Winch Trucks and Truck Cranes accompanied by lifting activities have a high risk with 14 loading loads per moving rig. With far distance between sub working area and various obstacles such as river, bridge load limit, land and river transportation types resulting in long rig moving time. In 2019, to the second semester 2020 the loss when moving rigs reached USD 1,483 Million. The limited number of lifting and transporting equipment, the number of equipment and the loading-unloading process are the dominant cause for long moving rig time. To solve this problem, we modify the rig equipment into an On Trailer with the aim to arrange all Rig operational support equipment on the trailer both during operation and moving, and to reduce the number of loads, rig moving time and the risk of lifting. On Trailer is equipped with Handrail & walkway, sets of manual jacks, and trailer and prime mover connection including pneumatic line system. After the implementation of On Trailer, the frequency of loading, unloading and setting work drops to 9 times lower so the potential for tool damage decreases, moving rig time managed to decrease to 9.6 hours thus decrease rig personnel workload. By using On Trailer, it successfully reached cost efficiency of USD 1,354/well, the risk of work accidents due to lifting & rigging activities minimized to 9 times and reduce the CO2 emission is 2,487 Gj/year due to decrease of fossil fuel consumption.
