Unconventional ‘shale’ reservoirs will continue to be a focus of the energy industry in North America for the foreseeable future. The bulk of the costs incurred in producing shale reservoirs comes from frac design and completions. With the price of oil still somewhat volatile, it is in the interest of energy companies to use data on hand to plan their horizontal wells so that they can stay in zone, and ultimately complete the wells in the optimal zone of interest.
Shale reservoirs tend to be heterogeneous in nature, with facies that differ in mineralogy, and as a result, geomechanical properties. What if a company could integrate knowledge of the geomechancial rock properties from their pilot wells into their well planning? 
We present a workflow that evaluates the mineralogy and geomechanical rock properties of an offset well, and incorporate that information into the planning stages of a horizontal well. Ideally, geologists can take advantage of their knowledge of geomechanical facies and optimally place a well so that it leads to better placement within the reservoir sweet spot.

After receiving her MSc, Kim entered the energy industry, and now has over 15 years of experience. She worked at Halliburton and Paradigm before spending two years as the petrophysicist for the Pike Asset team with BP in Calgary.  Kim recently rejoined Paradigm, applying her practical petrophysical experience to the work she does with the Geolog Formation Evaluation application.
