The whole process from the beginning of petroleum geological survey in the basin to the optimization of favorable oil-bearing zones. This is the most basic and integral oil and gas exploration based on the region, which has the characteristics of comprehensiveness, regionality and integrity, and is a multi-type comprehensive exploration method Users should apply this data in the context of regional geological surveys and exploration activities, accounting for advancements in theories of gas formation and exploration technologies. Methodological advice includes immediate evaluation of gas reserves upon discovery, precise component analysis of natural gas, and adjusting exploitation plans based on target area conditions. Users should also consider recent technological developments in virtual exploration and remote sensing when interpreting the data. It is essential to incorporate the pressure conditions of reservoir fluids, specifically in contexts similar to the development of shale gas in Sichuan Basin.
