Distributed Acoustic Sensing (DAS) Data for Periodic Hydraulic Tests

Published by California State University | Department of Energy | Metadata Last Checked: August 03, 2025 | Last Modified: 2019-01-31T20:42:13Z

California State University Long Beach evaluated hydraulic connectivity among geothermal wells using Periodic Hydraulic Testing (PHT) and Distributed Acoustic Sensing (DAS). The principal was to create a pressure signal in one well and observe the responding pressure signals in one or more observation wells to assess the permeability and storage of the fracture network that connects the two wells. DAS measured strain at mHz frequency in monitoring wells in response to PHT.
