(39) PINPOINT FRAC-ISOLATION TECHNOLOGY COMBINED WITH MEASURED DOWNHOLE DATA ENABLES CONTROLLED OPTIMIZATION OF MULTISTAGE COMPLETIONS

Today, E&P companies are being challenged to improve economic performance. Since completions are a major cost, it is imperative to improve completion efficiency and maximize production results.  A new controlled approach to multistage completions combines predictable frac placement (spacing and propped volume) with bottom-hole pressure and temperature data recorded during stimulation to enable progressive, formation-specific optimization of stimulation designs and frac delivery. The approach relies on single-point frac placement, using a coiled-tubing-deployed isolation system that incorporates downhole data recorders. The presentation describes single-point stimulation technology, discusses the value and interpretation of downhole pressure and temperature data, and reviews a number of optimization case histories.
