Daftar Isi:
- Lapangan Hijau oil reservoir is located in the Southern part of Rokan PSC, Central Sumatera Basin, Indonesia. It is one of the high potential and prolific fields that have been producing oil for over 40 years. Lapangan Hijau has hydrocarbon accumulations in tidal sediments, mainly in proximal tidal bars deposit. Those sediment bodies are deposited through vertical interval ranging from 10 to hundreds of feet. Nowadays, the challenges are to identify and exploit remaining oil reserves in these high water saturation reservoirs. This reservoir is locally known as the “Z sands”. It was deposited at depth between 4500ft to 5000ft. During the last few years, considerable efforts have been done to develop and optimize oil production from the “Z sands”. This paper describes the efforts to gain better geological understanding by integrating all available data including core, well logs, and well test data. As a result three new well locations and two existing deepening opportunities were identified. This paper highlights the importance of using an integrated approach to further develop a mature waterflood oil field.
