Abstract

This paper was first published in GEOExPro magazine, Vol. 18, No. 1, 2021, both in print and electronically (Koning et al., 2021) and is republished with permission from GEOExPro. For Berita Sedimentologi we have made various changes to the existing text and figures by including further results from our ongoing in-depth research into the geology of basement oil and gas plays in Sumatra.

This paper provides and up-to-date and in-depth review of the status of exploration for oil and gas in naturally fractured and weathered basement throughout Sumatra.  Also reviewed is the status of oil and gas production from Sumatra’s basement fields.  In this paper’s section on Economic Impact, we emphasize the major positive contribution to Indonesia’s economy resulting from gas produced from basement reservoirs in the South Sumatra Basin.  

Author Biographies

Tako Koning, Consultant

From 1980 – 1987 he worked for Caltex (Chevron & Texaco) in Rumbai, Pekanbaru on oil exploration and field development in the Central Sumatra Basin and also first-time ever oil exploration in the Ombilin Basin, West Sumatra.  The work included the development of the Beruk Northeast (NE) Field which produced oil from Pre-Tertiary basement.  Tako and F.X. Darmono published on Beruk NE in the proceedings of the 1984 IPA Convention, Jakarta.  He subsequently published a paper Oil and Gas Production from basement reservoirs: examples from Indonesia, USA and Venezuela in the Geological Society’s 2003 Special Publication on “Hydrocarbons in Crystalline Rocks”.  Since then, he has shared his knowledge by frequently presenting papers on global occurrences of basement oil and gas reservoirs at conferences and symposiums worldwide.

Nick Cameron, GeoInsight Ltd.

From 1977 and 1982 Nick was a member of the Bandung based, North Sumatra Project, a joint Directorate of Mineral Resources (DMR) - British Geological Survey (BGS) initiative.  Subsequently, he was contracted to Conoco Indonesia (Mahato Mandian Block) and Caltex (Ombilin Basin).  From 1982 employment was with Conoco working initially in Indonesia (Sumatra and Irian Barat) before moving to West Africa.  Indonesian publications include Sumatran microplates, their characteristics, and their role in the evolution of the Central and South Sumatra Basins (Proc. 13th Annual Convention IPA, Jakarta, 1984) which was co-authored with Pulunggono.

John Clure

He has worked in the oil business for 52 years as a geoscientist covering all continents and all aspects from operations to basin analysis including field development.  Approximately 21 of these years he was a resident of Indonesia.  During this time, he wrote the section on Fuel Resources: Oil and Gas in the Geological Society’s Memoir 31, dated 2005: “Sumatra – Geology, Resources and Tectonic Evolution”.
