Mono Trip Cement Through Gas Lift Completion: Innovative Completion System to Develop Oil-Gas Reservoirs in The Mahakam Delta

Abstrak

Handil is a mature oil and gas field located in the Mahakam block, East Kalimantan, Indonesia, which has been produced since 1975. Until now, oil from this field has contributed at least 70% of the total oil production produced from Mahakam block where 90% of the wells are using gas lift technology.
The utilization of gas lift technology has evolved in such a way that began with the use of dual strings with Side Pocket Mandrel (SPM), Retrievable Gas Lift (REGAL) which uses Gas Lift Pack-Off and Gas Lift Macaroni to increase lifting capacity through workover activities, to the latest using a technology called Mono Trip Cement Through Gas Lift Completion or abbreviated as MTGL which significantly reduce completion cost.
The main objective of this paper is to share the experience of the MTGL system installation in two (2) Handil wells in the end of 2017. The utilization of this system has had a significant impact to increase well economy by reducing rig operation time to 1.3 days per well and avoid potential future workover cost to install gas lift system in the wells that were not previously equipped with gas lift system.
