Untapped Oil Reserves Discovered in Bonan Sag, Transforming Energy Landscape
The researchers analyzed the fan delta system in the Bonan Sag area. They studied the rocks and sediments to understand how they were deposited. They found that the fan delta was the main depositional system, with shallow lakes in the background. In some parts of the area, small-scale fan systems were also present. The reservoir rocks mainly consist of siltstone, sandstone, and pebbly sandstone, with properties that are important for oil and gas accumulation.
