Case History: Using a Communications Protocol to Reduce Wiring Costs DuringConstruction of Well Test Headers

摘要

We installed several systems that used Actuator SensorrnInterface (Asi) bus to simplify and economize the wiring ofrnvalves on well test headersrnheaders1 in California oilfields. Using arncommunication protocol like Asi bus (or DeviceNet) reducesrnthe amount of wiring and conduit that must be purchased andrninstalled for each well test header. We have achieved costrnreductions by using Asi bus communication on well testrnheaders. As with introduction of any new technology, therernwere numerous “lessons learned.” We present ourrnrecommendations for installing Asi bus systems.
