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.
- 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.
- More than 48,000 Kazakhstanis working on FGP-WPMP in country, which is 91 percent of the total project workforce in Kazakhstan.
- TCO has engaged Kazakhstani entities to participate in FGP-WPMP in engineering, procurement and fabrication services and has pre-screened over 2,200 Kazakhstani companies and pre-qualified more than 1,800 companies. FGP-WPMP KC Spend since project start totaled $6.7 billion.
Project Progress Worldwide
- Engineering progressing is more than 90 percent complete.
- The main FGP-WPMP equipment is being fabricated in Kazakhstan, South Korea and Italy, and pre-assembled into modules for transportation to Tengiz for final installation and assembly.
