Abstract:
The very nature of reservoir stimulation with hydraulic fracturing is to introduce controlled deformations in tight formations to create extensive networks of flow paths to large surface areas. With a comprehensive understanding of the geological context, the formation deformations can be managed to create the fracture networks without compromising well structure, access or integrity. However, the geological context is complicated and acquiring enough information to rigorously characterize it is difficult. Knowledge of formation stresses is fundamental for design, but significant uncertainties are typical. Anisotropy of formation strength (which generally correlates to formation stiffness) can affect fracture characteristics. The mismatch between the orientations of formation strength and stress can further complicate the nature of formation deformations associated with the fracturing process and make predictions difficult.
Problems arising from formation behaviors that differ from predictions can range from insignificant, to missing production targets, and even well failure. This presentation will illustrate how mechanical diagnostics of the structure can be extended to understand fracturing behavior and, in turn, how the geomechanics description can be refined. Illustrations of how casing deformation modes reveal directionality of fracture orientations and relative movements of the fracture surface are included. Quantifying and locating movement impacts on the wellbore, useful for planning ongoing developments, is also discussed. Methods for interpreting relative movements on fracture surfaces by transforming casing deformations from the wellbore frame of reference to the global fracture frame of reference will be shown.
Speaker Bio:
Trent Kaiser is a founder of Noetic Engineering, an engineering consultancy that is now part of the Volant Products group of companies. He holds mechanical engineering degrees from the University of Alberta, including B.Sc. (1983), M.Sc. (1987) and Ph.D. (1991). His work has been predominantly research-oriented, focused primarily on well structure issues and wellbore flow mechanics. His specialization in developing and applying nonlinear numerical techniques has been applied to determining post-yield casing performance and limits, and to novel coupled wellbore hydraulics models of SAGD production. He is the primary developer of three caliper log interpretation algorithms commonly used by industry for determining casing deformations. He holds several patents covering a variety of inventions ranging from simulation algorithms, threaded connection designs, seal mechanics and manufacturing processes.
