Future Growth Project - Wellhead Pressure Management Project
- In 2016, TCO Partners announced approval for the final investment decision of the Future Growth Project - Wellhead Pressure Management Project (FGP-WPMP), the next major expansion of the Tengiz oil field.
- FGP will expand production by approximately 12 million tonnes per year/260 thousand barrels per day to about 39 million tonnes per year/850 thousand 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.
- Since the commencement of FGP-WPMP, TCO has spent over $16.3 billion to purchase Kazakhstani goods and services.
- The construction on the Wellhead Pressure Management Project (WPMP) is largely complete. The project focus is on commissioning and start-up and beginning the transition of the field from high to low pressure.
- The fuel gas system for the project’s Third Generation Plant (3GP) is now ready for operations and the first 3GP Gas Turbine Generator as well as two trains of the Pressure Boost Facility (PBF) compressor are mechanically completed.
