Typical North American shale wells are characterized by long horizontals and multiple stages of hydraulic fracturing. In most cases, the completions and production is left unmonitored. This requires the completion and reservoir engineers to assume that the fracs are being placed and are productive as designed, without any confirmation. In few select cases, the number of fractures has been determined with pressure diagnostics, radioactive tracers, or permanent fiber optic monitoring.
This presentation will discuss an additional method which uses Distributed Temperature (DTS) with an intervention. This new method takes advantages of the fact that the cooling from a hydraulic fracture remains in the reservoir for long periods of time (months).
Kyle Friehauf is a Senior Completions Engineer in the Completions Technology group of ConocoPhillips in Houston. His responsibilities included identifying and developing technologies for hydraulic fracturing and other stimulation methods.
His current focus is on interpretation of well monitoring data in unconventional resources. He has been at ConocoPhillips since 2009. He has a PhD from the University of Texas and BS from the Colorado School of Mines, both in Chemical Engineering.
