Mathematically rigorous, computationally fast, and easy to use, this
new approach to electromagnetic well logging gives the reservoir
engineer a new dimension to MWD/LWD interpretation and tool design
Almost all publications on borehole electromagnetics deal with
idealizations that are not acceptable physically. On the other hand,
"exact models" are only available through detailed finite element or
finite difference analysis, and more often than not, simply describe
case studies for special applications. In either case, the models are
not available for general use and the value of the publications is
questionable.
This new approach provides a rigorous, fully three-dimensional solution
to the general problem, developed over almost two decades by a
researcher familiar with practical applications and mathematical
modeling. Completely validated against exact solutions and physics-based
checks through over a hundred documented examples, the self-contained
model (with special built-in matrix solvers and iteration algorithms)
with a "plain English graphical user interface" has been optimized to
run extremely fast - seconds per run as opposed to minutes and hours -
and then automatically presents all electric and magnetic field results
through integrated three-dimensional color graphics.
In addition to state-of-the-art algorithms, basic "utility programs" are
also developed, such as simple dipole methods, Biot-Savart large
diameter models, nonlinear phase and amplitude interpolation algorithms,
and so on. Incredibly useful to oilfield practitioners, this volume is a
must-have for serious professionals in the field, and all the algorithms
have undergone a laborious validation process with real use in the
field.
