Paper: Successful Installation of Full-Scale Distributed Processing Supervisory Control and Data Acquistion System at Two West Texas Waterfloor Units

TEXACO U.S.A. has successfully installed an automation system which provides distributed remote control and monitoring of the entire array of producing operations at the Wharton and Robertson Waterflood Units in Gaines County, Texas. A preliminary economic analysis of the project indicates that the benefits attained have exceeded expectations. Microprocessor based Remote Terminal Units (RTU's) are used to detect and report alarm conditions and operating data to a Master Terminal Unit (MTU) located in a field office on the Wharton Unit. RTU's have been eveloped to provide the following functions: 1.) Control beam pumped wells. 2.) Monitor variable speed driven electric submersible
pumped wells. 3.) Monitor and control individual injection wells. 4.) Perform automatic well testing and monitor the operation
of the production satellites. 5.) Monitor the operations at the tank batteries. 6.) Monitor and control the water injection plants.
