Australia's first offshore CaTS deployment

摘要

This novel application of the CaTS technology was installed in the Thylacine field, operated by Woodside Energy Ltd and located in the Otway Basin off Victoria in South Eastern Australia. CaTS is a revolutionary development in the field of reservoir monitoring and control that allows real-time information to be transmitted to and from downhole without the use of a direct cabled connection in the well. Its two-way transmission capability enables the remote control of downhole instrumentation, opening the path to the radical redesign of downhole completions. The CaTS system was installed in a Thylacine well in July 2006 as part of a lower completion assembly that provided zonal isolation between immediately producible reservoir layers and a separate zone, potentially producible in the future. CaTS transmits its data from the reservoir zone being monitored, to a pick-up located further up the well, then onwards to surface using Expro's market leading wireless telemetry technology. The design uses a CaTS receiver located on the unmanned platform topside to collect, process and store the data from downhole. This data is then transmitted from the receiver to the client's onshore facility.
