Premise: Geological applications
of well logs are as broad as geology itself and petroleum geologists
can learn from their colleagues in other disciplines.

Realization: The Geological
Applications of Wireline Logs
, a 1999 conference sponsored by
the Geological Society of London, used that premise as its theme.

Result:
The newest volume in AAPG’s
Methods in Exploration Series, No. 13, includes papers from
that conference in a publication that offers good reading as well
as a chance for geologists — even the most veteran — to get a
fresh look at well logs.

The papers were intended to promote cross-fertilization
among the three geological constituencies: practicing petroleum
geologists, log users in other industries and academic researchers.

The book is divided into three sections (each introduced
by an overview paper describing the principles involved). They are:

  • Technology and techniques, featuring NMR,
    real-time measurement, thin-bed analysis and the ability to
    “geo-steer” the drill stem to a precise target.

  • Sedimentology, introduced by John Doveton
    (University of Kansas), a section that emphasizes rock features
    that can be determined by using well logs.

    The section also includes papers on resistivity images, paleocurrents
    and stratigraphy of the oceanic crust.

  • Stratigraphy and fractures in the stress
    field. Covered are fluid flow, fracture networks, crustal features
    and discussions on underground storage of nuclear waste and development
    of geothermal energy.
