To increase your
knowledge of the formation we offer log analysis services
which include the integration of logging data with core
analyses and geologic core descriptions. By this way we
are able to characterize the subsurface related to its
structure, lithology and physical properties. As a log
analysis tool we use the professional Interactive
Petrophysics software package to quality check the
log data and to carry out multi-zone, multi-well
petrophysical field analyses.
Among others the different modules
enable statistical analyses to estimate missing log curves
and predict permeability and lithofacies from core data
and the analysis of image logs.
Based on standard methods of
well-log interpretation including rock classification and
determination of the shale volume, porosity and water
saturation we developed specific routines to calculate
continuous profiles of physical properties such as
permeability and thermal conductivity. In our calculations
we account for differences in vertical resolution and
radial length of investigation which are attended by the
various measurement methods.
Beside conventional sedimentary
environments, we off expert interpretation knowledge also
for unconventional reservoirs of shale and tights gas,
fractured crystalline formations and volcanic rocks.
