Tengiz Field Development

Return to the previous page. Go back

The Tengiz field was discovered in 1979 and in 1993 TCO acquired this field. With high quality, recoverable oil reserves of over 6 billion barrels and 18 BCM of gas, Tengiz is one of the largest fields in the world.

The remote location of the field and the harsh climatic conditions and limited infrastructure, our local experience has been a critical element to our success on this project.

Kentech has been involved in a number of projects at Tengiz since 2003, these projects include:

  • Procurement and construction of key mechanical/ HVAC aspects at the SGI (Sour Gas Injection) facility.
  • Establishment of a Kazakh certified instrumentation calibration laboratory, and electrical and instrumentation services for East and West Tengiz and the Korlev field.
  • Provision of electrical services throughout the facility.

In 2008 we undertook the following projects directly for TCO:

  • Electrical and instrumentation installation on the Crude Tank Farm
  • Electrical and instrumentation installation for the Gas Utilisation Project firstly on the Vent Gas Recovery (first stage) and the Unit 800 (second stage)

At the beginning of 2010, we were awarded a shutdown contract by TCO on the SGI and SGP.

In 2012 we provided them with commissioning and start-up support services on the Sulphur Expansion Project.

We completed turnaround works on the SGP Plant in 2016, and on the Crude Stabilization Facility (KTL Plant) in 2017 and 2018.

We also executed the E&I scope of works on the Water Handling Upgrade Project at Tengiz in 2014-2016, as well as providing additional commissioning and start-up services.

In the next phase of development at the Tengiz plant, the Future Growth Project, is already seeing the Kentech/TCO relationship grow.

Kentech have been awarded three separate 5 year Master Services Agreement (MSA) to support TCO with their growth plans. The first MSA is to assist the Future Engineering Group (FE), the second is for Major Capital Projects (MCP) and the third is to support Production Operations (PO) which as at February 2020 has seen the team deliver over 387,000 manhours, 1.7 million manhours and 1.01 million manhours respectively.

We have also been awarded the commissioning scope of works on the 3GI plant as well as executed E&I construction scopes on Stage 2 Power & Lighting and 110KV substations on both 3GP & 3GI.


On Tuesday 9th February 2021, we announced an agreement to acquire the oil & gas business of SNC-Lavalin’s Resources Division.

This business includes people and assets brought together through their acquisition of the Kentz and other energy services businesses. This transaction marks an exciting, ground-breaking development for Kentech to reinforce our position as a leading integrated energy services provider and introduces us to the renewable / clean power marketplace. We now move forward together with a global network of more than 10,000 professionals united by a commitment of common values and strong partnerships with clients from across the world.

By investing now, we are strategically positioning the company to take advantage of the next cycle of growth.

Our complementary businesses will join forces, creating a stronger offering across the full asset life cycle – from consulting to design and build, commissioning and start-up, through to maintenance, modification and turnaround, as well as decommissioning services.
