Future Growth Project - Wellhead Pressure Management Project
General Information
- 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.
Kazakhstani Content
- Since the commencement of FGP-WPMP, TCO has spent over $14.2 billion to purchase Kazakhstani goods and services.
Project Progress
- With the project now 93% complete, the remaining work scope is focused on Tengiz.
-
Recent key project milestones include:
- Integrated Operations Control Center (IOCC) is operational
- Cluster 55 First Oil was achieved on June 13th.
- Electrical Substation energized for Pressure Boost Facility
- FGP-WPMP is a project of national importance and is helping to create a legacy of a trained and skilled local workforce, technology transfer through partnerships with international companies, and upgraded infrastructure in the region.
