EAGE E-Lecture: Calibration of distributed acoustic sensing (DAS) VSP data by Mark E. Willis

Vertical seismic profiling (VSP) is a technology used to characterize seismic properties of the earth in a large volume surrounding a well. The goal of this lecture is to familiarize the viewer with a new technology, distributed acoustic sensing (DAS), that makes VSPs quicker to acquire and easier to repeat. DAS uses fiber optic cables as sensors, replacing geophones for recording the seismic wave field. First a brief introduction of the DAS technology is presented. Then VSP data from DAS and geophones are compared and calibrated to demonstrate the big uplift possible using this new technology.
