Geomechanical analysis on casing deformation in Longmaxi shale formation
Journal of Petroleum Science and Engineering, 2019Abstract Casing deformation is the most significant problem while developing Longmaxi shale gas formation in Sichuan Basin, southwest China. In one of the operating acreages with 72 horizontal wells, 38 wells encountered casing deformation problems after several stages of hydraulic fracturing treatments.

Study on Anisotropy Affection Factors of Longmaxi Formation Shale
78th EAGE Conference and Exhibition 2016, 2016Summary The Silurian Longmaxi Formation shale in Sichuan Basin is an important shale gas reservoir for shale gas exploration in China, but the anisotropy of Longmaxi shale is not studied sufficiently. In this case, the velocity anisotropy is examined under the reservoir pressure conditions by ultrasonic testing method.

Research on Brittleness of Shale in Longmaxi Formation, the Southeastern Chongqing Area
2013 International Conference on Computational and Information Sciences, 2013This article studies Longmaxi exposures in southeast of Chongqing, and carries on experiments to analyze the feasibility of the fracturing from the aspect of brittleness. The results show that the shale is well bedded, tight, and has low porosity and low permeability in this area. And it needs to be reconstructed. The analysis of the mineral components

Experimental investigation of the stress-dependent permeability in the Longmaxi Formation shale
Journal of Petroleum Science and Engineering, 2019Abstract Understanding the stress sensitivity mechanism of the matrix permeability in shale is crucial for reservoir evaluation and gas production forecasting. However, the shale matrix has a heterogeneous pore structure and a complex material composition.

Experimental Study on the Wettability of Longmaxi Formation Shale in the Sichuan Basin, China
International Petroleum Technology Conference, 2020Abstract The wettability of conventional reservoirs have been extensively studied in the past. However, Shale is rich in organic matter, composed of many mineral components in complex relationships, and contains pores of various scales from micrometer to nanometer, so it is very difficult to evaluate the wettability of shale.

Experimental Study on Water Imbibition Law of Longmaxi Formation Shale in the Sichuan Basin
International Petroleum Technology Conference, 2021Abstract Water imbibition is a key factor affecting the flowback system of shale gas wells after volume fracturing. This paper took shale samples from the Longmaxi formation (LF) in the Sichuan Basin as subjects, the experiments of shale water imbibition under different influencing factors were carried out.

Elastic parameter inversion of Longmaxi Formation shale based on the least squares method
Arabian Journal of Geosciences, 2021Elastic parameters are important parameters in the study of shale anisotropy, exploration, and development, and their accuracy is of great significance. In this study, shale in the lower Silurian Longmaxi Formation of southeastern Chongqing was investigated by obtaining the acoustic velocity of the partial bedding angle through an acoustic transmission

Shale geological features of Qiujiahe (Є1q) and Longmaxi (S1ln) Formation
2015The main purpose of this research paper is to compare Qiujiahe Formation (Є1q) and Longmaxi Formation (S1ln) in north Sichuan basin where shale gas exploration has not been fully researched, and hence represents the possibility of shale gas concentration under the complex geological conditions. Based on valid laboratorial analysis, there are optimistic

Marine and Petroleum Geology, 2019
Abstract A large, typical, marine, organic-rich shale is developed in the Ordovician Wufeng Formation-Silurian Longmaxi Formation in the Sichuan Basin, China, which has rich shale gas resources. This paper uses this type of shale as an example to analyze the influence of the depositional environment on the enrichment mechanisms and sedimentary ...
