Panel Session Overviews
The Value of Geomechanics for Drilling
Facilitator T.Finkbeiner (OMV E&P)
To make reliable predictions for drilling (e.g.mud windows,
casing point depths, uncertainty assessment etc.) geomechanics relies on a variety of data, assumptions, calibrations, and
criteria each of which generally influence the results in a noticeable 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 Development
Facilitator: 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 poroelasticity and Hubbert and Willis on hydraulic fracturing, through
to Geertsma’s work on subsidence, Bradley’s paper on wellbore
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
• 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.

Dr. Manhal Sirat has over 26 years of multidisciplinary experience in industry and academia with project management skills.
Dr. Sirat is currently working as the Structural Geology/­
Geomechanics Specialist at EUFR. His assignments include planning, supervising, QC and conducting studies, mentoring and
­provide technical assistance for Structural Geology and Geomechanics applications for EUFR and ADCO Assets. He also act as
the Principal Researcher for the Subsurface Fractures Characterization (SFC) Group at the AR&D Division in ADCO, where he
helps attracting and developing UAE talents and develops capabilities 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, conferences & workshops.
Mohammed Ameen (Saudi Aramco)
Mohammed holds a PhD in Structural Geology and Geomechanics 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 classification, 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 mechanics, coupled behaviour of fractures, and rock engineering
for tunnels.
