Introduction to Petroleum Geomechanics: A three part series

This three-part webinar series is focused on introducing the basics of geomechanics and geomechanics services to a wide audience - from service approvers (management), to engineers and scientists who might be called upon to support and evaluate the value of geomechanics efforts but who do not have specific training in geomechanics. While presented as a three-part series, the webinars are laid out in a fashion from more general to more technical.

The first webinar is intended to present a high-level explanation and background on geomechanics for individuals who would both consider the need for geomechanics as well as determine the value for a given application. What geomechanics is (and isn’t) will be presented as well as some history and explanation of what geomechanics technical competence might look like.

The second and third webinars are focused on specific technical issues surrounding geomechanics: formation stress, formation pressure, formation mechanical properties (and strength) and the influence of geometry. In a fair amount of detail, stress will be explained as well as its implications. Similarly, formation pressure (and the effect of pressure changes during production) will be presented. Then, formation mechanical properties and strength will be discussed, particularly in light of oil and gas operations (e.g., drilling a wellbore or depleting a reservoir). These two webinars will conclude with a presentation of the criticality of geometric issues, such as fault location and orientation and lithological variations, on geomechanics evaluations.

  • Module 1: Overview of Petroleum Geomechanics

    Contains 3 Component(s), 0.15 credits offered Recorded On: 11/14/2018

    The focus of this webinar will be on defining what geomechanics is, why/when it is important in oilfield operations, and the history and technical competence of geomechanics.

    The focus of this webinar will be on defining what geomechanics is, why/when it is important in oilfield operations, and the history and technical competence of geomechanics. This webinar is primarily focused on decision-makers and less-technical individuals who have a need to understand geomechanics from a cost/value perspective, but who would not be expected to specify or evaluate geomechanics services themselves.

    Dr. Neal Nagel

    Chief Engineer, OilField Geomechanics LLC

    Dr. Nagel has over 30 years of industry experience having worked for ConocoPhillips for 20 years and as a consultant since then. He is a well-known expert in petroleum geomechanics and, specifically, the geomechanics of Unconventionals. Nagel has given many invited SPE, AAPG, HGS, SEG, and SPWLA presentations and training courses and has authored or coauthored more than 50 technical papers, with 20+ related to Unconventionals, including a keynote presentation at the 2014 SPE HFTC. He is currently the chairman of the SPE Geomechanics Technical Section, a recent petroleum geomechanics track lead for the annual ARMA conference, is a past SPE Distinguished Lecturer (2004 and 2016), was chief editor of the 2010 SPE Monograph on Solids Injection, and has served on the SPE Drilling and Completions Committee and been a local SPE section officer.

  • Module 2: Introduction to Earth Stresses

    Contains 3 Component(s), 0.15 credits offered Recorded On: 11/28/2018

    The focus of this second webinar in the series will be on defining the issues and the critical role that formation stress, strain (deformation), and formation pressure have on the geomechanics of oilfield applications.

    The focus of this second webinar in the series will be on defining the issues and the critical role that formation stress, strain (deformation), and formation pressure have on the geomechanics of oilfield applications.

    Stress and strain will be defined and the critical aspects (e.g., the role of effective stress) of these will be highlighted. Measurement of these in the field will also be presented. In addition, this webinar will touch on the important role that formation pressure – and specifically changes in formation pressure – plays in oilfield geomechanics. The webinar will also touch on the means to predict and measure formation pressures.

    Dr. Richard Plumb

    Principal Consultant, Plumb Geomechanics, LLC

    Dr. Plumb is principal consultant at Plumb Geomechanics, LLC and a visiting scholar at Tufts University. He is a globally recognized geoscientist with over 45 years of geomechanics experience worldwide. Previously he worked 29 years for Schlumberger.  He spent 15 years in research helping to develop the science and borehole measurements used to characterize earth stress and rock mechanical properties.  For the next 14 years he led the geomechanics consulting business and the geomechanics technical domain within Schlumberger.

    His recent work includes: developing geomechanical models supporting planning and drilling exploration wells drilling in tectonically active regions of Iraq and Peru; mentoring Ph.D. students at M.I.T. and Tufts University and providing geomechanics training. His current interests include: understanding how mineral composition and texture affects the rheology of sedimentary rock and factors that govern the contemporary state of stress in sedimentary basins. 

    Dr. Plumb holds a B.A. in Physics and Geology from Wesleyan University, a M.A in Geology from Dartmouth and a Ph.D. in Geophysics from Columbia University.  He holds 6 U.S. patents and has over 70 publications in academic and industry journals.  He is an active member of the American Geophysical Union, the Society or Petroleum Engineers, the American Rock Mechanics Association and the Society of Petrophysicists and Well Log Analysts.

  • Module 3: Formation Mechanical Properties and Geometry Effects

    Contains 3 Component(s), 0.15 credits offered

    The focus of this webinar will be on defining the issues and the critical role that formation mechanical properties and strength and structural geometry have on the geomechanics of oilfield applications.

    The focus of this webinar will be on defining the issues and the critical role that formation mechanical properties and strength and structural geometry have on the geomechanics of oilfield applications.

    Mechanical properties and strength will be defined and the critical aspects (e.g., the assumption of elastic behavior) of these will be highlighted. Measurement of these in the field from log data as well as the important role of core testing will also be presented. In addition, this webinar will touch on the important role that geometry plays in a geomechanical evaluation including fault orientation in 3D space, well trajectory, and variations in mechanical properties and strength across a given evaluation domain.
