The main geological factors controlling the Wufeng- Longmaxi shale gas content [PDF]

open access: yes, 2022
Changning and Fuling are two of the best-known shale gas fields in China, located at two different depositional centers of the Upper Ordovician Wufeng Formation to the lower Silurian Longmaxi Formation in the Sichuan Basin. However, there are significant

Classification and Evaluation on Shale Gas Reservoir for Wufeng-Longmaxi Formation in Chuannan Area, Sichuan Basin [PDF]

open access: yesLithosphere, 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 ...

Integrated Petrophysical Evaluation of Shale Gas Reservoirs for Wufeng-Longmaxi Formation in Southeast Chongqing

open access: yesIOP 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.

Complex Resistivity Anisotropy Response Characteristics of Wufeng-Longmaxi Formation Shale in Southern Sichuan

open access: yesMinerals, 2022
Electrical exploration has become an important means of shale gas reservoir exploration and evaluation, and is expected to play a key role in the later stages of reservoir fracturing and development. At present, the research on the electrical response characteristics of shale gas reservoirs and their relationship with reservoir parameters is extensive ...

Geological difference and its significance of marine shale gases in South China

open access: yesPetroleum 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.

Coupling effects of temperature, confining pressure, and pore pressure on permeability and average pore size of Longmaxi shale

open access: yesDeep Underground Science and Engineering, Volume 2, Issue 4, Page 359-370, December 2023., 2023
This paper investigates the permeability characteristics and average pore size of Longmaxi shale under different temperature and pressure conditions. A customized high‐temperature and high‐pressure core permeability instrument was used to carry out seepage experiments on the Longmaxi shale.

Lithofacies identification of shale formation based on mineral content regression using LightGBM algorithm: A case study in the Luzhou block, South Sichuan Basin, China

open access: yesEnergy 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.
