17.4.1 DAS Workflow

Figure 17.4.1-1 shows a very high-level DAS workflow. Assets such as wells and pipelines are fitted with fiber optic cables. DAS interrogator systems are connected to these fibers and collect huge volumes of raw acoustic data. The raw data is collected in the field, often some pre-processing takes place to extract relevant data and reduce the data volume. The raw and/or extracted datasets are then transferred to the office where they are further processed and stored. Oil and gas software uses both the raw and processed data as inputs for applications such as surveillance.
