  • TCO’s current gas utilization rate is over 98 percent.
  • Investments in equipment reliability have reduced the number of technical malfunctions at the plants and the volume of unplanned sour and acid gas flaring during technical malfunctions by 84 percent from 2000 to 1Q2017. 
  • Total air emissions generated per tonne of oil produced have been reduced by 70 percent since 2000, even as annual crude oil production has grown by 2.5 times as a result of TCO’s investments in capital programs and equipment reliability.

    • Based on TCO’s highly-successful SGI/SGP expansion project, FGP will expand production by approximately 12 million tonnes per year/260,000 barrels per day to about 39 million tonnes per year/850,000 barrels per day. 
    • WPMP will keep the existing Tengiz plants full by lowering the flowing pressure at the wellhead and then boosting the pressure to the inlet requirements of the six existing processing trains.
  • The main FGP-WPMP equipment will be fabricated in Kazakhstan, South Korea and Italy and pre-assembled into modules for transportation to Tengiz and final assembly.
  • FGP-WPMP has completed 60 percent of overall engineering.
  • Tengiz infrastructure construction is progressing according to plan, as is the Cargo Transportation Route (CaTRo).
  • Pipe racks fabrication works commenced at ERSAI yard in Mangystau Oblast, Kazakhstan, in October 2016 and currently is progressing according to plan.
  • At peak construction and fabrication, FGP-WPMP is expected to create about 20,000 jobs.
