Sedimentary Facies of the Chang 2 Member of Yanchang Formation in Area A of Northern Shaanxi [PDF]
E3S Web of Conferences, 2021 In order to promote the rolling exploration and development of oil reservoirs in northern Shaanxi, a fine study of sedimentary facies in area A has been carried out. Using core and logging data, on the basis of identifying different levels of sequence interfaces and lake flooding, the Chang 2 Member in Area A was divided into two base level cycles, and

Fracability Evaluation of Lacustrine Shale in the Yanchang Formation of Southeastern Ordos Basin [PDF]
Energy Exploration & Exploitation, 2015 As a typical lacustrine shale in China, the Chang 7 shale in the Yanchang Formation of the Ordos basin shows great potential for development. Buried less than 2000 m deep, the shale is always characterized as a tight reservoir with well-developed bedding and cracks. Many studies have been performed on Chang 7 shale to determine its depositional systems,
