Panel Session Overviews

The Value of Geomechanics for DrillingFacilitator T.Finkbeiner (OMV E&P)

To make reliable predictions for drilling (e.g.mud windows, casing point depths, uncertainty assessment etc.) geomechan-ics relies on a variety of data, assumptions, calibrations, and criteria each of which generally influence the results in a no-ticeable way. The panel discussion will focus on the following critically important aspects• Is geomechanics able to solve all (most, few, none) of the

industries well-bore stability problems? • What are the criteria utilized to decide if a well bore is

stable or unstable? What are the assumptions these critera are based upon? How (un-)realistic are they?

• How important are other aspects to wellbore stability (e.g., mud chemistry, hydraulics etc.)

• Discuss real-life examples where geomechanics worked and where it did not work – why/why not, lessons learned, challenges, short comings etc.

The Future Role of Geomechanics in Field DevelopmentFacilitator: T. Addis (Baker Hughes)

The contribution of the geomechnical behaviour of reservoirs and surrounding formations to field development has gradually increased over the years, from the early work of Biot on poroe-lasticity and Hubbert and Willis on hydraulic fracturing, through to Geertsma’s work on subsidence, Bradley’s paper on wellbore

EAGE Workshop on Geomechanics in the Oil & Gas Industry4

stability, geomechanics has touched on numerous aspects of field development from exploration through development drilling, and production. The panel discussion will focus on the potential future role of geomechanics, or geomechanical engineering, in field developments, addressing;• Which field developments are likely to require significant

geomechanical engineering input, and how can we influence asset managers to gather the required data to assess the risks and to identify mitigation options

• Are we able as an industry to recognize the underlying causes of problems, to justify and focus appropriately future improvements?

• Do we have to wait for future disasters to spur another step change in the inclusion of geomechanics in field development?

• If we have to wait for potential or actual disasters, are we able to identify risks that we are likely to encounter in future field developments?

• Discuss real-life examples where geomechanics worked and where it didn’t work – why/why not, lessons learned, challenges, short comings etc.

He then worked as a lecturer in the Depart-ment of Mineral Exploitation at University College Cardiff, and a co-director of the Strata Mechanics Research Group. He returned to the now Department of Mining and Petroleum Engineering where he created a rock mechanics research group and was pro-moted to Professor. Prof Smart moved with his research group and lab to the Institute of Petroleum Engineering at Heriot-Watt University, where he was head for seven years, ultimately becom-ing a Vice Principal of the University with responsibility for the creation and development of the Heriot-Watt University Dubai Campus. He is now Rector of Global College Malta, which is de-veloping teaching partnerships with foreign universities such as Robert Gordon University and Chester University.

Manhal Sirat (ADCO)Dr. Manhal Sirat has over 26 years of multidisciplinary experi-ence in industry and academia with project management skills. Dr. Sirat is currently working as the Structural Geology/ Geomechanics Specialist at EUFR. His assignments include plan-ning, supervising, QC and conducting studies, mentoring and provide technical assistance for Structural Geology and Geome-chanics applications for EUFR and ADCO Assets. He also act as the Principal Researcher for the Subsurface Fractures Charac-terization (SFC) Group at the AR&D Division in ADCO, where he helps attracting and developing UAE talents and develops capa-bilities through knowledge transfer and close coaching of the SFC R&D Group. Dr. Sirat taught several professional long term and short term oil industry courses, and has published more than 70 publications in peer reviewed international Journals, confer-ences & workshops.

Mohammed Ameen (Saudi Aramco)Mohammed holds a PhD in Structural Geology and Geome-chanics from Imperial College, London and is the Principal Professional, Geomechanics and Unconventional Resources at Saudi Aramco. Since July 2012 Mohammed has been Lead Geomechanics Consultant for Unconventional Resources in the Unconventional Resources Exploration Department, Saudi Aramco, focusing on unconventional prospects evaluation, stimulation and delineation. He has vast experience in diverse reservoirs across Saudi Arabia (carbonates, clastics, conventional and unconventional) and set a paradigm shift in understanding fractures impact on deeply buried carbonate reservoir performance (Khuff Reservoir, AAPG Bulletin, January 2010, and JMPG, February 2014). 

Nick Barton (Nick Barton Associates)Nick holds a Ph.D. in rock mechanics from Imperial College and is the developer of the widely used Q-system of rock mass clas-sification, and main developer of the Barton-Bandis constitutive model for the coupled shear-flow behaviour of rock joints, used in distinct element codes. He has more than 8,000 citations of his work and is author or co-author of 275 papers on rock me-chanics, coupled behaviour of fractures, and rock engineering for tunnels.
