Controlling Effect of Wave-Dominated Delta Sedimentary Facies on Unconventional Reservoirs: A Case Study of Pinghu Tectonic Belt in Xihu Sag, East China Sea Basin by Qinglong Chen, Renhai Pu, Xiaomin Xue, Ming Han, Yanxin Wang, Xin Cheng, Hanning Wu

“…The results show that two stages of regression and one stage of transgression occurred in the Pinghu Formation, resulting in river-controlled and wave-controlled delta-neritic facies dominated by sedimentary facies, source rocks developed in interdistributary bay and swamp microfacies, and tight sandstones in point bar and distributary channel microfacies are developed. The accumulation of coalbed methane and shale gas is controlled by the sedimentary facies and the degree of thermal evolution under the factors of burial depth. …”

Feldspar Dissolution and Its Influence on Reservoirs: A Case Study of the Lower Triassic Baikouquan Formation in the Northwest Margin of the Junggar Basin, China by Meng Xiao, Xuanjun Yuan, Dawei Cheng, Songtao Wu, Zhenglin Cao, Yong Tang, Zongrui Xie

“…Based on the analyses of core and thin section observations, QEMSEM, XRD, SEM, CL, fluorescence, and image analysis software combined with logging and physical property data, this study shows that feldspar dissolution in the subaqueous distributary channel of a fan delta plain, which has good original physical properties and low mud contents, significantly improves the properties of the reservoir. …”

Textural Characteristics and Depositional Regime of the Shitalakshya River Sediments, Bangladesh by Sohag Ali, Mrinal Kanti Roy, Md. Mahmodul Islam, Zillur Rahman, Faruk Ahmed, Abdul Alim, Md. Yeasin Arafath

“…The analyzed samples have unimodal, bimodal, and polymodal distribution, which indicates the sediments are carried by different tributaries and distributaries in the Sitalakshya River system. The range of 1.46Ø–4.05Ø represented by the observed mean value suggests sand with medium to extremely fine grains. …”
