Published techniques for after-closure analysis of f
racturing data usually assume the presence of a vertical fracture intersec
ting a vertical well. In addition, these published techniques usually assu
me that the formation is homogeneous. When the formation is naturally frac
tured or the well is horizontally intersecting a transverse vertical fract
ure, those assumptions are obviously violated and the published analysis t
echniques might not be applicable. Through the use of analytical and numer
ical solutions and application to actual field data, this paper investigat
es the analysis of after-closure data for heterogeneous formation, natural
ly fractured data, CBM, and fractured horizontal well.
This paper
briefly reviews the various available techniques for after-closure analys
is, pointing out the strengths and weaknesses of each. An analytical solut
ion for injection falloff test for a naturally fractured formation has bee
n developed and is presented. This solution might be used to analyze data
for a MiniFrac test in a naturally fractured formation where the fractured
has healed. Numerical simulation validated the developed solution for a f
racture that has healed. The same numerical simulator was used to expand t
he solution to a situation where the fracture maintains residual conductiv
ity.
The solution for a MiniFrac test in the case of a transverse
fracture is also presented and discussed. Using a numerical simulator, Mi
niFrac tests are simulated and analyzed for both heterogeneous formations
and a fractured horizontal well. Guidelines for analysis of such data have
been developed and presented.
Field data are also presented. One
case presents a MiniFrac test for a heterogeneous formation. A case for a
transverse fracture intersecting a horizontal is also presented and analy
zed. A third case for CBM is discussed.
