Eyes On The Prize – what microseismic monitoring is telling us about completions in unconventional reservoirs.
Peter M. Duncan
The analysis of microseismic data has progressed greatly over the last 10 years. The limited value displays of hypocenter locations in still or animated views are being replaced by more realistic, quantitative products that are demonstrably more valuable to the completions engineer, the reservoir engineer and the development geologist. These products include a discrete fracture network description of the treated volume, a quantitative mapping of the insitu stress regime over the treatment area, a quantitative estimate of the propped and unpropped permeability enhancement as a result of the frac and early time estimates of production and drainage area for monitored wells. Microseismic monitoring offers the opportunity to make a real time, well specific, insitu observation of the permeability enhancement achieved through stimulation, one that incorporates all the specifics of a particular treatment program as well as the local variability in rock properties, natural fracturing and stress state. In other words microseismic monitoring provides a window through which to view what is happening in the reservoir during stimulation. This presentation will describe some of the observations on unconventional completions that monitoring has revealed with examples from the field.
