This multi-disciplinary course combines technical skills in all subsurface and well engineering disciplines to provide Geomechanics solutions to field scale and individual well problems. A fundamental knowledge of Petroleum Geomechanics is a key part of good field development planning because Geomechanics often underpins optimised engineering and has been proven to realise significant project cost savings. This course will give you some tools to avoid wellbore instability, sand production, subsidence and compaction, fault re-activation and poor hydraulic fracture performance to list a few examples. If you are considering water injection, cuttings injection or gas injection and storage then the Petroleum Geomechanics course will be an important step to assuring that your injection and storage goals are achieved. Have you considered that your tight gas development could suffer from stress dependent permeability induced decline or that your fractured reservoir will lose the conductive fractures with time due to depletion and stress path effects? The Petroleum Geomechanics course is an interesting and interactive course which covers a wide area of applications which can be pivotal for best field development success. If you need to understand any of the features of the graphic below and you want to know how to design for these then this course will be ideal for you.

WHAT YOU WILL LEARN 

• Geomechanical Model Building Using drilling information, well logs and core data, you will learn how to build full Geomechanical models which include magnitude and orientation of principal Earth stresses, pore pressure and rock mechanical properties. You will learn how to design, manage and QA/QC rock mechanics core tests. You will learn to cross check your model with regional stress and rock strength databases.
• Sand Production Prediction You will learn how to predict sand production in injection and production wells under drawdown, depletion and following water breakthrough. You will see a real time example of oriented and selective perforation. You will see how sand production prediction helps production technologists and completion engineers to find and implement an optimum sand control and management strategy.
• Wellbore Stability Analysis You will learn how to analyse wellbore stability for generic and optimum well trajectories using your own calibrated geomechanical model. You will provide your own optimum safe mud weight windows using pore pressure, shear failure, tensile fracturing and permeable fracture limits, along a complete well path. Special cases such as shallow gas hazards, chemically reactive rocks, weak bedding planes, natural fractures and faults, salt domes and underbalanced or managed pressure drilling will also be addressed.
• Fracture Stimulation Optimisation You will learn about the geomechanical constraints of hydraulic fracture performance. Treatments can be optimised to maximise net present value (NPV) while mitigating complex issues such as undesirable fracture growth, multiple fracturing, fracture tortuosity, premature screenouts and inadequate proppant coverage. Fracturing can also be optimised for unconventional applications such as geothermal reservoirs, coal bed methane gas reservoirs, naturally fractured reservoirs, CO2 injection, produced water injection and drill cuttings injection.
• Basin and Reservoir Deformation You will learn about fault reactivation caused by production induced changes in Earth stresses and reservoir pressures. Reservoir compaction and the associated effects that can cause well damage and lost production: permeability reduction, surface subsidence, fault and bedding place movement will also be covered. Geomechanical assessment of fault sealing and stability is essential for underground gas storage and CO2 sequestration projects so this area is a hot topic.

WHO SHOULD ATTEND
Drilling Engineers, Completion Engineers, Production Technologists, Petrophysicists, Core Analysts, Geologists and Reservoir Engineers involved in aspects of field development planning. Anyone involved with wells and subsurface management of fields will benefit from this course because early introduction of good geomechanics can avoid costly field development mistakes. Basic Geomechanics principles are reviewed; however a few years experience in the Petroleum Industry is desirable.
