SPE Forum Series: The Role of Geomechanics in Conventional and Unconventional Reservoir
Performance and Management

22 - 24 May 2016 :: Kuala Lumpur, Malaysia

Technical Agenda

Wellbore Geomechanics

Session Chairpersons: Jeremy Meyer, Ikon Science; Chee Phuat Tan, Schlumberger

This session will focus on the input data, modelling methodologies and applications of wellbore geomechanics to address potential issues for the life of the well. The discussion will cover rock mechanical testing, calibration of models with field/well data, and the pros and cons of analytical versus numerical models. Impact of wellbore geomechanics on well integrity, production/injection deliveries, and recent field cases will be presented.

Reservoir Geomechanics

Session Chairpersons: Zis Katelis, Gaffney, Cline & Associates; Stephen Tyson, U. of Queensland

In reservoir geomechanics, it is critical to have an adequate description of in-situ stress magnitude and orientation and how they may evolve with field development. These stress changes affect most reservoirs but have greatest influence on reservoirs in which flow is through fractures, either natural or induced. This session will be of particular interest to those studying unconventional fields; Coal Bed Methane, Shale Gas, Tight Gas and High Pressure High Temperature fields.

Geomechanics for Unconventionals

Session Chairpersons: Ray Johnson, Unconventional Reservoir Solutions; Jamaal Hoesni, PETRONAS

In exploiting unconventional resource plays, the importance of geomechanics has increased from simply deriving a stress profile for hydraulic fracturing to other aspects of geomechanical evaluations towards development decisions. Outside the North America, geomechanics challenges and impact on unconventional reservoir development can be more pronounced, especially where significant variability in stress magnitudes and non-normal stress regimes are present.

The session would build on the failures and successes of current practices of geomechanics in the design, interpretation and modelling of hydraulic fracture stimulations and seek areas for future improvement. But the scope of geomechanics in unconventional reservoirs has grown to include the geomechanical effects on reservoir performance, natural fracture behavior, and interaction of the hydraulic fracture with structural features such as faults. Moreover, the link between geomechanics and the application of diagnostic technologies such as surface deformation tiltmeters and microseismic monitoring is critical in getting maximum value out of these surveillance technologies. This session explores these emerging areas of geomechanics using recent field cases in the growing area of unconventional geomechanics.

Recent Geomechanics Innovations

Session Chairpersons: Claudia Santana, Halliburton; Amitava Ghosh, Baker Hughes

The field of Geomechanics is constantly evolving and improving in support of exploration and production.  Although there are a number of 'tried and true' methods in the industry, what are the latest innovations in Geomechanics? This session will focus on Geomechanics at the forefront of research and development, incorporating ground breaking alternative models as well as plate mechanics, geothermal, volcanology and hydrology. The discussion will focus on how the application of these innovative methods may add values to the oil and gas industry and how can they be applied to further improve efficiency in the industry.

Geomechanics Skills and Capability Development

Session Chairpersons: Chong Zhou, PETRONAS; Satya Perumalla, Baker Hughes

Petroleum geomechanics is a relatively new and evolving subsurface discipline. Developing geomechanics competency in the industry is an active pursuit. It requires a good integration to other subsurface disciplines (geosciences, reservoir, drilling engineering, etc.) in order to maximise the impact of geomechanics on hydrocarbon recovery. This session will discuss new methods and means to train up and coming petroleum engineers and geoscientists, focus on how to provide better integration of geomechanical data throughout lifecycle of a well, as well as tackle the issue of physical data to digital data - how to take advantage of the vast amounts data monitored and simulated through digital sensors and software. Also from the corporate level, how to attract juniors to practice geomechanics and further progress their career path have posed challenges to both managers and HRs. In this regard, carefully designed competency matrix, dedicated training roadmap, cross-discipline interaction and mentoring scheme will be shared and discussed by participants coming from academia, service providers and operators.

Field Cases – Learning from Success and Failure

Session Chairpersons: Ashok Shinde, Baker Hughes; Mohamad Khodaverdian, Shell

Much of the subsurface process safety issues regardless of their root causes could eventually culminate in geomechanical failure and potential loss of containment. This session intends to focus on actual field studies and experiences of applying geomechanics (or the lack of such application) in field development and reservoir management. Specific field cases include drilling and completions, HPHT field development, unconventional field development, compaction and subsidence, waterflooding and EOR, disposal operations, surveillance and abandonment.  Some of these field cases will demonstrate the importance of integrated workflow between geomechanics and other disciplines for problem solving.
