Scope of services

Dr. Roland Braun - Consultancy in Rock Mechanics advises national and international Oil & Gas, Energy, Mining and Tunnelling companies about special rock mechanics aspects of their activities.

The principal services supplied are:

Determination of fundamental input parameters for geomechanical rock mass analyses & modelling (3D in situ stresses and strain, strength data for any 3D stress conditions etc.).

Evaluation of borehole stability & sanding including a clarification of the causes of observed instabilities.

Straightforward optimization of relevant drilling parameters (such as borehole path, mud pressure & draw down etc.).

Determination/forecasting of rock deformations/compaction resulting from pore pressure changes.

Assessment of the load dependent mechanical integrity of rock masses.

Technology & tools

For the specialized rock mechanics analyses sophisticated technologies and easy to use tools have been developed in-house by Dr. Roland Braun – Consultancy in Rock Mechanics.

The principal expert systems are:


Drill core analyses to identify/analyse the 3D in situ stresses.


Assessment of rock stability/sanding around boreholes.


Evaluation of the load depended mechanical integrity of the rock mass far from openings.

Related systems are:


Definition of the rock strength under any 3D loadings.


Explanation of sudden effective stresses changes resulting from rock loosening.
