Oil treatment facility
Nostrum finalised the construction of an oil treatment facility in 2006 (“OTF”). Currently the OTF has a maximum annual throughput capacity of 400,000 tonnes per annum.
Raw gas processing infrastructure
The gas treatment facility (“GTF”) uses a gas utilisation concept, and was designed to treat raw gas from gas condensate reservoirs (and the associated gas coming from the OTF) into three separate products – stabilised condensate, LPG and dry gas. The GTF associated infrastructure includes a power generation station, an LPG storage tank farm, an LPG loading facility at the rail terminal, LPG railcars and a 17km dry gas pipeline.
GTU1 & 2
The GTF currently includes two gas treatment units, each with the capacity to treat approximately 850 million cubic metres of raw gas per annum. The GTF is currently operating close to nameplate capacity.
The third treatment unit of the GTF was mechanically completed in 2018, with commissioning beginning in 2019. Once commissioned, GTU3 will add 2.5 billion cubic metres of additional raw gas processing capacity, bringing the Group’s combined capacity to 4.2 billion cubic metres per annum.
Power generation plant
The gas-fired power generation plant is linked to the gas treatment facility with an output of 15 megawatts. The generation capacity from the plant is sufficient to meet the existing and anticipated energy needs of the field site and associated operations as the Company grows production.
Nostrum has its own 17km gas pipeline which was completed in 2011 and is linked to the Orenburg Novopskov gas pipeline. The maximum annual throughput of this pipeline is several billion cubic metres.
Nostrum has its own 120km liquids pipeline that was completed in 2008. The pipeline runs from the field site to the Company’s rail loading terminal in Uralsk. The pipeline has a maximum annual throughput capacity of over three million tonnes.
Rail loading terminal
Nostrum commissioned its own automated rail loading terminal in the city of Uralsk in 2009. The rail loading terminal currently receives all domestic crude oil and export condensate produced by Zhaikmunai and has a capacity of approximately four million tonnes of crude oil and condensate per annum.
Nostrum has over 30,000 cubic metres of storage capacity for liquids at its field site and rail loading terminal.
KTO pipeline connection
During 2017 Nostrum completed the construction of a secondary crude oil pipeline to enable export sales via the Atyrau-Samara international export pipeline operated by KazTransOil. The KTO pipeline substantially reduced Nostrum’s crude oil transportation costs by more than 50% and has enhanced the Company’s ability to manage crude oil netbacks through the commodity cycle. The total completion cost of the KTO pipeline was under US$7 million and the project was completed on time and under the projected budget of US$10 million.
Low Pressure System
During 2018 Nostrum completed and commissioned new a Low Pressure System which aims to reduce the decline rates of ageing gas condensate reservoirs through reducing the inlet pressure of the main manifold at the GTF from 10 to 42 bar.
