“…In the paper titled "Analysis of Accumulation Mechanism of Guantao Formation in Matouying Uplift of Jidong Oil field and its Exploration Inspiration" (Wang et al 2022), the determination of oil sources and the correct understanding of the transport system were the keys to the reservoir understanding of the Guantao Formation in Matouying Uplift, as well as to the establishment of the reservoir model and the prediction of favourable oil and gas development areas. It provided the enlightenment for the exploration of reservoir outside sources in peripheral convex, and although oil and gas displays have been seen during single-well drilling, no large-scale reservoirs have been discovered until the industrial flow of oil.…”
