Tenge Oil and Gas Field is located in the second largest oil and gas-rich belt of the Republic of Kazakhstan, adjacent to the giant Uzen Field, with superior geological conditions. The development of Tenge Oil and Gas Field is divided into two phases. From 1970 to 2000, the focus was on natural gas development, mainly in the upper Middle Jurassic strata XIII-XVII, with a significant production scale, making it the second-largest gas field at the time. From 2000 onwards, the lower Middle Jurassic strata XVIII-XXIII began to be exploited for oil and gas, with a lower degree of extraction.

Between 2021 and 2022, ZPEC Group reprocessed the 3D seismic data of this oil and gas reservoir, re-evaluated the reservoir, and, reported to the government of Kazakhstan at the end of 2022, obtaining approval for C1+C2 crude oil geological reserves of 78.54 million tons and dissolved gas geological reserves of 8.65 billion cubic meters. In 2023, capacity building was implemented for the oilfield, and construction work for the CPF in the region was fully resumed.

As of April 2026, Tenge Oilfield has 98 production wells, 78 active wells, and 4 water injection wells. In 2025, the annual wellhead oil production was nearly 300,000 tons, with newly added production capacity of 150,000 tons.

In 2025, the application of horizontal well staged fracturing technology in Well 22H-03 achieved success, making it the first well in our history to produce over 100 tons of oil per day. On October 9, 2025, the gas-fired power station at Tenge Oilfield was officially put into operation, supplying power to the central processing facility, Station 1, 3, and 4, as well as the western power line.
