                          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.
