Borehole Image Log Interpretation
Reservoir
characterisation: Can you see what the logs are saying?
Image logs can provide essential information for reservoir characterisation.
Our service uses PC-based software (ImageLog) to provide information on;
- Natural fractures and
faults; type, orientation, relative timing, apparent
aperture, spatial distribution
- Induced fractures and borehole shape;
location and attributes of breakouts (including width), axial
tension fractures
- Sedimentology; image log
facies, depositional architecture and geometry, correlation to
core, lithology, reservoir zonation

Image logs are usually rich in data, some of
which may not be relevant. With over a decade of experience
in image log interpretation, we know
how to recognise and extract
the key information. We provide impartial, high quality interpretations that will help you gain the most
from your image logs.
Features of the service include;
- loading of LIS/DLIS data from all
industry-standard borehole image log tools, and from wells of
any deviation,
- loading of other open hole logs alongside
the image, and digital core photos,
- interpretation by qualified and experienced geologists and
geomechanics engineers,
- integration of dynamic data to identify the subset of
producing features,
- geostatistical analysis of fracture data including correlation
for wellbore trajectory,
- preparation of fracture data for input to reservoir fracture
models,
- determination of in-situ stress orientations and magnitudes,
- evaluation of the influence of in-situ stress on fracture
permeability,
- integration of image log facies with core sedimentology to
support reservoir zonation, and
- preparation of "fly-through" visualisations showing borehole shape and
fracture intersections (GeoTV).
