MicroSeismic introduced a series of completions-evaluation services to quantify and predict reservoir drainage and production. These new services advance completions evaluation for unconventional wells beyond the commonly used modeling approach to a new observation-based approach. The newly developed analysis methods use observations taken directly from the reservoir, capturing the effects from hydraulic fracturing, providing more-accurate specific estimates of future incremental production and estimated ultimate recovery (EUR). These services help operators develop entire fields better by predicting accurate per-well and per-stage performance just weeks after completion. The first of the services is PIndex, an estimate of the well’s relative productivity. It shows a direct comparison of well productivity and identifies differences between wells, providing immediate feedback to adjust overall completion strategies. The second service, DIndex, quantifies the well’s current and future reservoir drainage volume and drainage pattern. The result is a map of future incremental reservoir depletion, showing when drawdown pressures from adjacent wells will interact with each other. Finally, Production Forecast is a service that predicts each well’s future incremental production and EUR after the well is completed. Because the Production Forecast is based on the post-treatment reservoir, it has been far more accurate than other common statistical methods for predicting production.
