Distributed Sensing in Geophysics

Dr. Andres Chavarria (OptaSense)

Abstract:              DAS was introduced more than ten years ago. First applications included seismic imaging using VSP for high resolution and time lapse analysis.  With the development of unconventional reservoirs fiber optic DAS has now become a critical tool to monitor in real time stimulations and production. This has extended the range of applications from microseismic into strain and temperature from the same Interrogator Unit. Fiber optic applications and analysis based on geophysical techniques is now routinely used to diagnose different devices within instrumented assets in the borehole or on surface.  The distributed nature of DAS with high receiver density has enabled geophysicists to implement traditional analysis tools to a wide variety of disciplines.  In this presentation I show examples of various applications of DAS sensing from traditional seismic processing and imaging, completions monitoring as well as newer engineering applications.

Bio:        Andres Chavarria is OptaSense’s  Oilfield Services Technical Director. His current focus is the use of distributed sensing fiber optic data for engineering and geoscience applications.  He has a background on borehole seismology (MS and VSP) and was previously the Geophysical Processing Manager at SR2020 and Paulsson. He has conducted work in other areas of geophysics including geothermal, mining and groundwater. He holds an Engineering Degree on Geophysics from UNAM and a PhD Degree on Geophysics from Duke University.
