The development phase in Mahakam Delta, East Kalimantan, Indonesia requires cost effective solution to safely monitor production test routine while maintaining low operational cost. Well testing barges has been utilized since the early development phase and it enables several testing operation such as well offload, production test and clean up after perforation. However, the system reaches its technical limits in term of cost and operation time. Developing alternative production test solution is required to monitor wells productivity while maintaining robust safety environment. The alternative system shall reduce significantly well testing time and allowing simple equipment layout. Multi-Phase Flow Meter (MPFM) is considered as alternative solution to cut well testing cost for production testing job. The next Generation MPFM provides superior data accuracy compared to its predecessor. It consists full spectrum analysis enabling the most precise fraction measurement of oil,gas and water to date. To validate the use of MPFM, trial in Handil and Tunu field is planned. Mobile MPFM unit temporary installed in a selected well testing barge. Simultaneous data acquisition from MPFM will be recorded in upstream flow relative to well test separator measurement. Data from well test separator will provide as measurement reference independent to MPFM data. Intensive works on Well Testing design and equipment layout were performed and it was decided to start trial in Handil Oil field. MPFM layout design is optimized to avoid data inaccuracy due to complex temporary line while maintaining ergonomic working environment. Special well start up procedure was established to ensure the accuracy of MPFM data acquisition. To date, several oil wells and gas wells in Handil and Tunu field have been tested using MPFM. Initial production tests in Handil field shows relatively accurate gas and liquid flow rate compared to separator data. The success of this initial trial gives a good base for improving and confirming well testing cost reduction.
