Mysterious "supercharge effects," encountered in formation testing
pressure transient analysis, and reservoir invasion, mudcake
growth, dynamic filtration, stuck-pipe remediation, and so on, are
often discussed in contrasting petrophysical versus drilling
contexts. However, these effects are physically coupled and
intricately related. The authors focus on a comprehensive
formulation, provide solutions for different specialized limits,
and develop applications that illustrate how the central ideas can
be used in seemingly unrelated disciplines. This approach
contributes to a firm understanding of logging and drilling
principles. Fortran source code, furnished where applicable, is
listed together with recently developed software applications and
conveniently summarized throughout the book. In addition, common
(incorrect) methods used in the industry are re-analyzed and
replaced with more accurate models, which are then used to address
challenging field objectives. Sophisticated mathematics is
explained in "down to earth" terms, but empirical validations, in
this case through Catscan experiments, are used to "keep
predictions honest." Similarly, early-time, low mobility,
permeability prediction models used in formation testing, several
invented by one of the authors, are extended to handle supercharge
effects in overbalanced drilling and near-well pressure deficits
encountered in underbalanced drilling. These methods are also
motivated by reality. For instance, overpressures of 2,000 psi and
underpressures near 500 psi are routinely reported in field work,
thus imparting a special significance to the methods reported in
the book. This new volume discusses old problems and modern
challenges, formulates and develops advanced models applicable to
both drilling and petrophysical objectives. The presentation
focuses on central unifying physical models which are carefully
formulated and mathematically solved. The wealth of applications
examples and supporting software discussed provides readers with a
unified focus behind daily work activities, emphasizing common
features and themes rather than unrelated methods and work flows.
This comprehensive book is "must" reading for every petroleum
engineer.
