Exploit the relationship between in-situ stress and permeability
to produce more effectively from fractured reservoirs. Leverage
our expertise for superior recovery.
Natural fractures and faults are the primary pathways for hydrocarbon
migration and production in many reservoirs, and critically stressed faults
(preexisting faults active in today's stress field) can systematically
control permeability, and hence high fluid flow. Let our experts turn this
information into better well decisions through field-specific geomechanical
models enabling:
- Detection of variations in stress magnitudes affecting permeable fracture sets
- Optimization of drilling direction to intersect zones enhancing permeability
- Characterization of variations in fracture attributes in adjacent fault blocks
3-D Mohr diagrams clearly illustrate that hydraulically
conductive fractures and faults are critically stressed (left
diagram) whereas those which are not conductive are not
critically stressed (right diagram). Critically stressed faults are characterized by ratios of shear to effective normal stress above 0.6, the same range of values found in laboratory
friction tests.

Improved Trajectories through Improved Insight
Knowing the orientation of permeable fractures can help you optimize well
trajectories to intersect the maximum number of permeable fractures. It all starts
with wellbore images, the fundamental data for optimizing reservoir drainage. Using
our GMI•Imager application, we'll characterize and classify natural
fractures and faults, giving measurements of orientation, distribution, and apparent aperture.
Next, GMI•MohrFracs is used to analyze the fracture data, along with the reservoir stress profile
derived from GMI SFIB™, to determine the proximity of fracture and fault sets to frictional failure. From
there, your critical well planning decisions are made easier. Optimize design, drill for the permeable
zones and enjoy the peace of mind and extra profit that comes with good decision-making.
