As the organization has just been restarted, we use LinkedIn (www.linkedin.com) as the main data base platform. We realize that it is not the ideal solution, and we may look for other alternative in the near future. Having said that, for the current situation, LinkedIn is fit for purpose.

Corresponding author: [email protected] INTRODUCTION study is limited. The wells in Pertamina Fields area cover the Tanjung, Kambitin, Tapian Timur and Paleogene age rocks are exposed over about 40% of Warukin Fields. Some seismic sections in this area Borneo island, mainly in the central or core part. have been published by Satyana (1995). The geologic map (Figure 1) shows that more than half of those Paleogene exposures are grouped as a Unocal, Lasmo and Pertamina, respectively, melange unit and the rest are a mix of sediments operated blocks in the Kutei Basin and they shot and meta-sediments (Tate, 2002; Hutchison, 1989). seismic in the 90’s. Some of their seismic surveys The majority of the melange unit is exposed in were followed by drilling into the Paleogene target Malaysian Sabah and Sarawak. The Paleogene intervals (Figure 1). Seismic sections of the sediments are exposed more in the Indonesian Paleogene interval in Kutei Basin were published (Kalimantan) side. and incorporated into the preparation of the paleogeographic maps (e.g. Satyana & Biantoro, Within the sedimentary basins around Borneo, the 1996; Saller & Vijaya, 2002). Moss and Finch Paleogene interval lies buried deep and is poorly (1997) have collected outcrop data from Upper understood. Seismic images covering the Paleogene Kutei area. interval are poor and the number of Paleogene well penetrations is limited. Most well penetrations The Tarakan basin has the least data for the stopped within the Neogene interval only, where Paleogene compared with the other two basins in significant hydrocarbon accumulations have been East Kalimantan. However, it has the latest data, found (Figure 1). from Bella-1 well, (drilled by ACG PTE Ltd in 2013), which penetrated Eocene volcanics. There are a few Several authors have provided a regional overview older wells drilled close to the basin margin, of the basins in East Borneo, namely: Barito, Kutei targeting the Paleogene interval and only two wells and Tarakan (e.g. Satyana et al., 1999; Darman & encountered the Eocene section, Bella-1 and Sidi (eds.) 2000 and Netherwood, 2000). Recently Bunyut-1 (drilled in 1975). Seismic data for the the Paleogene in East Kalimantan became a Paleogene interval is also limited for this basin. petroleum exploration target (Saller & Vijaya, 2002; Satyana & Biantoro, 1996 and Guritno & Chambers, 1999), unfortunately no significant STRATIGRAPHY accumulations have yet been found. The three sedimentary basins of East Borneo, the This short article summarizes the distribution of Barito, Kutei and Tarakan basins, contain many Paleogene rocks in the east of Borneo Island based hydrocarbon
