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:

►	RACOS^®:	Drill core analyses to identify/analyse the 3D in situ stresses.
►	BOREHOLE:	Assessment of rock stability/sanding around boreholes.
►	ROMEIN:	Evaluation of the load depended mechanical integrity of the rock mass far from openings.

Related systems are:

►	GLAST:	Definition of the rock strength under any 3D loadings.
►	MOPP⁺:	Explanation of sudden effective stresses changes resulting from rock loosening.
