MIC and partners successfully acquire dip-in DAS dataset
As part of MIC’s ongoing research program, the University of Calgary partnered with sponsors ARC Resources and OptaSense, and wireline and conveyance service providers ESG Solutions and Altus Intervention, to acquire a wireline (dip-in) distributed acoustic sensing (DAS) monitoring dataset in northeastern BC in January 2021. The dataset was acquired to monitor a multi-well completion program in the Montney play to support research on low-frequency interwellbore strain, development of a comprehensive workflow for DAS microseismic processing and evaluating the effectiveness of dip-in DAS observations compared with permanent fibres. Real-time monitoring showed clear frac hits for 54 stages, at offset distances of more than 300m. The results of this experiment support the effectiveness of dip-in DAS acquisition and represents an exceptional example of academic-industry research synergy. Initial results from processing and interpretation of this dataset will be presented to MIC sponsors at the 2021 Annual Sponsors Meeting.
