Description du livre
This timely book begins with an overview of shale gas
reservoir features such as natural fracture systems, multi-fractured horizontal
wells, adsorption/desorption of methane, and non-linear flow within the
reservoir. Geomechanical modelling, an aspect of importance in ultra-low
permeability reservoirs, is also presented in detail.
Taking these complex features of shale reservoirs into
account, the authors develop a numerical model, which is verified with field
data using the history matching technique. Based on this model, the pressure
transient and production characteristics of a fractured horizontal well in a
shale gas reservoir are analysed with respect to reservoir and fracture
properties. Methods for the estimation of shale properties are also detailed.
Minifrac tests, rate transient tests (RTA), and type curve matching are used to
estimate the initial pressure, permeability, and fracture half-length. Lastly,
future technologies such as the technique of injecting CO2 intoshale
reservoirs are presented.
The book will be of interest to industrial practitioners, as
well as to academics and graduate students in the field of reservoir
engineering.
