Efficiency Improvements for Distributed Acoustic Sensing Data Exchange Streamline Operations and Opens Access to New Uses

Distributed Acoustic Sensing (DAS) is being applied to an increasingly broad number of use cases across the whole life cycle of a hydrocarbon asset. There is a pressing need for the industry to adopt a standard data format to transfer, exchange and store this data, to address the huge data volumes and the inter-relational aspects of different versions of the data with respect to a given original recording set and the description of the data acquisition system . By formulating extensions to an existing packaging convention, making use of file formats optimized for large data arrays and specifying an indexing process, petabytes of data become manageable with rapid and precise access to specific recordings or processed data. A standardized method to store, access and extract data greatly facilitates exploring new uses and applications for DAS by researchers in operator or oilfield companies as well as academia. Implementations to date are discussed in the paper.
