Deepwater Mahakam Gas Reservoir Characteristics

Several deepwater gas reservoirs in the offshore Mahakam Delta in Indonesia have been discovered: Geliga, Gehem, Konta, Geng North, and Rangga. These gas discoveries are largely Miocene turbidite plays in the Kutei Basin—particularly middle to upper Miocene channel, fan, and basin-floor sand systems. These targets stand out for their strong reservoir quality, reliable gas charge, and the potential for large, laterally connected accumulations within combination traps....

Turbidite Oil Reservoirs Turbidite fields play a vital role in modern oil and gas exploration, particularly in offshore and deepwater settings where they often host large hydrocarbon reserves. As exploration increasingly shifts toward frontier basins, turbidites offer high-quality reservoirs with favorable porosity and permeability, supporting efficient hydrocarbon production. Historically, these reservoirs have made a major contribution to global petroleum supplies. Between 1894 and 1969, 11 giant turbidite fields (each exceeding 500 million BOE recoverable) added around 14 billion BOE....
