In 2019, Nostrum successfully completed and commissioned the third train (GTU-3) of its gas treatment facility. After introducing raw gas, each technological element of the GTU-3 system has been tested and verified independently. After achieving on-spec quality of the final products (sales gas, stable condensate, LPG), a 72-hour performance test was concluded. Following the successful performance test, while obtaining all necessary documents, regulatory acts, documents regarding industrial and fire-fighting safety, GTU-3 was declared ready for operation and became part of the Field Operation (as GTU-1-2-3). The total capacity of the gas treatment facility is now 4.2 billion cubic metres per annum. The third train has a capacity of 2.5 billion cubic metres per annum. The sulphur recovery unit allows Nostrum to process sour gas with an H2S content of up to 1.6% at the moment in direct oxidisation mode. This is part of the sour gas stream after processing before it gets into the Sulphur Recovery Unit. Work is ongoing on modifying the Sulphur Recovery Unit to allow for the UOG gas to be processed. Consideration will be given to enhancing the Sulphur Recovery Unit further, to allow for other third party gas with higher H2S content

In order to stabilise the decline of some of older producing wells, Nostrum commissioned a low pressure system in Q4 2018. There are now 12 wells linked up to the Low Pressure system, and further compressor capacity is required to prolong the life of the gas condensate wells. As a result, an extension to the low pressure system was approved in Q3 2019, and the extension is scheduled for completion in October 2020.
