Indonesia’s Geological Agency has begun an airborne survey in Sulawesi to identify potential new oil and gas reserves as the country seeks to expand hydrocarbon exploration and attract fresh investment, an official announced on Sunday. The survey is focused on the Lariang Basin in West Sulawesi and Enrekang in South Sulawesi, using Full Tensor Airborne Gravity Gradiometry (FT/AGG) to collect high-resolution subsurface data, said Edy Slameto, Head of the Geological Survey Center. Accurate mapping, he added, will provide industry players with more clarity on the hydrocarbon potential of the two regions. The airborne survey will cover approximately 33,000 kilometers of flight lines, using a fixed-wing aircraft for flatter terrain and helicopters for mountainous areas. Edy said the mission is expected to be completed within 35 days, subject to weather conditions. The targeted sites were selected partly due to their location near the Sengkang Basin, which currently produces natural gas used to supply electricity in South Sulawesi. The Geological Agency also began a 40-day offshore seismic survey on December 1 in the Gorontalo Basin using the Hai Yang Shi You 760 vessel operated by China Oilfield Services Limited (COSL). The basin is considered promising, supported by previous 2D seismic data. According to agency data, Indonesia has 128 identified sedimentary basins, but only 20 are producing hydrocarbons. The remaining 108 basins — many located in eastern Indonesia — are believed to hold significant potential despite higher geological risks, Edy said.
