How to evaluate a shale play? Part A Emanuel Martin Introduction Shale formations constitute 60% of the rocks that make up the Earth's crust being only a small group

Methods of Decline Curve Analysis for Shale Gas Reservoirs In this article, the eight most popular deterministic decline curve methods are reviewed: Arps, Logistic Growth Model,
Hydrulic Fracture
And three concepts were proposed, i.e., shale gas fracture network, ideal fracture network and appropriate-stimulation degree of fracture network. The study results indicate that, at
Therefore, the independently-developed CTSTA program is adopted to quantitatively describe the micro-fractures inside rock core, including fracture dimension, extension direction and extension scale. Meanwhile, this
