Harweel Early Development Facility (EDF) project was a USD 100Million 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 MAC scope dimension was USD 10Million provided by Yokogawa System Centre Europe who invited Abalto to provide the system integration, design and commissioning of Foundation Fieldbus instruments, valves, wellhead hydraulic control panels, Fibre Optic Converters and repeaters.

The production station Birba under the project scope had 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.

Abalto engineers had supervised construction and liaise with EPC to ensure quality completion which does not adversely introduce flaws that hinder commissioning.  Following structured pre-commissioning procedure and extensive testing helped mitigate hidden flaws in hardware and software.  We successfully integrated the MAC deliverables such as Yokogawa ProSafe IPS, Stardom FCS and FastTools to following third party system:

  • Nuevo Pignone Compressors LP, MP and HP compressors
  • Frames Wellhead Hydraulic Control Panels
  • Honeywell TDC 3000
  • Pepperl & Fuchs relay based shutdown system
  • Prognost Condition Monitoring system
  • Dymac VM600 vibration protection system
  • Haimo Multiphase Flow Metering units
  • Alan Bradley Utility UCP
  • ABB Variable Speed drives
