PDO Harweel EDF DCS & Safety Systems Commissioning, Start-up and Optimisation.

Project Description & Scope of Work

Description

Harweel Early Development Facility (EDF) project was a USD 100 Million project for Petroleum Development Oman aimed at assessing the viability of miscible gas flooding which would yield highest oil recovery from high pressure sour Oil & Gas reservoirs. The 4 reservoirs had 15 producing wells with flowing pressures from 260Bar to 700Bar and average H2S concentrations of 50,000ppm with 15% Co2. This challenging Enhanced Oil Recovery project demanded cutting edge technology to deliver using prototype compressors and state of the art control and safeguarding system due not only to the process parameters but the fact that the wells were located 80Km from the production station Birba hence the base of design was remote operations. The production station Birba under the project scope had a new separation train, 3 new reciprocating compressors, flare package and utility Air and Nitrogen generation packages. The oil production capacity added was 20,000 barrels of oil per day and 1.8 million meter cubes of natural gas.

Scope

The MAC scope dimension was USD 10 Million provided by Yokogawa System Centre Europe who invited Abalto to provide the system integration and commissioning of Foundation Fieldbus instruments, valves, wellhead hydraulic control panels, Fibre Optic Converters and repeaters. We were responsible to MAC from construction supervision through integration to successful commissioning, start-up and handover liaising with EPC to ensure quality completion not adversely introducing flaws that hindered the schedule. Following structured pre-commissioning procedure and extensive testing helped mitigate hidden flaws in hardware and software.
