Classification and Evaluation on Shale Gas Reservoir for Wufeng-Longmaxi Formation in Chuannan Area, Sichuan Basin [PDF]
Lithosphere, 2021 Abstract Based on the comprehensive statistic and analysis on some representative geological and physical data, the classification criteria on net pay for shale gas reservoir of the Wufeng-Longmaxi formation in Shunan area, Sichuan Basin, are proposed, which include porosity (φ), gas saturation (Sg), density of rock (DEN), brittleness ...

IOP Conference Series: Earth and Environmental Science, 2021 Abstract Shale gas is an important unconventional natural gas resource. Different from conventional oil and gas exploration, gas shale is not only the source rock of natural gas, but also the cap rock and reservoir. This paper presents a logging interpretation method for comprehensive evaluation of shale gas.

Geological difference and its significance of marine shale gases in South China
Petroleum Exploration and Development, 2016 Organic-rich marine shales are developed in both the Cambrian Qiongzhusi Formation and the Ordovician Wufeng Formation–Silurian Longmaxi Formation in South China, but are different in the drilling results of shale gas exploration.

Energy Science &Engineering, Volume 11, Issue 11, Page 4256-4272, November 2023., 2023 This study is based on logging data and core testing data, and uses machine‐learning algorithms to construct a regression model for the relative content of shale minerals. The regression prediction model and mineral ternary diagrams are used to classify and identify lithofacies.

Frontiers in Earth Science, 2023 In this study, the microscopic pore characteristics of shale in marine strata are evaluated. Based on field emission scanning electron microscopy (FE-SEM), low-temperature N2 adsorption (LT-N2GA), low-pressure CO2 adsorption (LP-CO2GA) and high-pressure methane adsorption (HPMA) experiments, the pore characteristics of 12 shales from the Wufeng ...
