Wireline
Measurements
We help you to
plan and organize borehole measurement operations for deep
drillings. We optimize the logging program to
your specific target and help you to find the best service
provider for your needs.
We perform logging campaigns in
shallow and medium deep holes in cooperation with the
Institute “Geothermal Energy and Applied Geophysics”
of RWTH Aachen University
The
following parameters are measured:
· Spectral
Gamma Ray Log - natural radioactivity of rock
total
gamma radiation (API)
element
concentrations of potassium (%), thorium (ppm) and uranium
(ppm)
· Induction
Log - electrical
resistivity of the rock formation
resistivity
measurements in air- as well as in water-filled boreholes
porosity
calculations aided by laboratory determination of a and m
· Sonic
Log -
velocity
of elastic waves
velocities
of compression, shear and surface waves are measured
recording
of the complete wave form
· Gamma-Gamma
Log - density
of rock
measurement
of bulk density in SI-units
porosity
calculations aided by laboratory determination of rock
matrix density
· Fluid-Logging
- measuring
temperature,
pressure, electrical
conductivity
To secure a high quality of
the logging results, the geometry of the hole is
continuously measured with a four-armed caliper tool. This
allows us to account for irregularities of the borehole
wall and to correct our data accordingly.
