REMOTE WELL MONITORING AND TESTING

A NUMBER OF BRUNEIíS OFFSHORE PLATFORMS ARE BEING MONITORED REMOTELY USING íS WELLHEAD MONITORING SYSTEM. THE PLATFORMS ARE UNMANNED WITH NO SAFE AREAS, SO ALL EQUIPMENT IS CERTIFIED FOR ZONE ONE HAZARDOUS AREAS.

Typical Shallow Water Unmanned Platform

BRUNEI SHELL PETROLEUM SELECTED íS ISRTU TO WORK IN THIS ENVIRONMENT. AS WELL AS BEING ENVIRONMENTALLY PROTECTED TO OPERATE ON OPEN DECKS IN CORROSIVE H2S GAS AREAS, THE EQUIPMENT IS CERTIFIED AS "INTRINSICALLY SAFE" FOR EXPLOSIVE ATMOSPHERES.

DATA IS TRANSMITTED TO A CENTRAL PLATFORM, OR TO SHORE WITH COMMUNICATION LINKS UP TO 22KMS. THE SYSTEM INTERFACES WITH WESTINGHOUSE DCS EQUIPMENT IN THE CENTRAL CONTROL ROOMS OF EACH OFFSHORE FIELD.

THE SYSTEM TRANSMITS DATA USING INTRINSICALLY SAFE UHF RADIO TELEMETRY. THE WELLHEAD MONITORING SYSTEM ISRTU IS DESIGNED FOR LOW POWER OPERATION, AND THE ENTIRE SYSTEM IS SOLAR POWERED.

ISRTU INCORPORATES COMPREHENSIVE LOCAL PROCESSING CAPABILITY, IN THIS CASE IT IS PROGRAMMED FOR FLOW TOTALISATION, AGA3 GAS FLOW CALCULATION, WELL TESTING AND PROTOCOL EMULATION.
