The operator of Ukraine’s gas storages Ukrtransgas JSC planned to perform overhaul of 10 wells and also work on intensification of 20 more on one of the West Ukrainian underground gas storages (UGS) in 2023.
“Well workovers continue these days at one of the West Ukrainian UGS facilities. The overhaul crew has completed work on the facilities renewed since 2022 and has begun new work,” the company said in a telegram on Wednesday.
“Ukrtransgas”, in particular, started a thorough inspection of the systems at two wells of the gas storage facility and, if necessary, will replace its individual elements. The aim of the works is to restore the productivity of these wells to the designed indicators and increase safety of their further operation.
“It should be noted that in 2022 about 20% of the well stock of this subway well was repaired”, – informed the JSC.
Last year the specialists of the UGSF overhaul group replaced the system components such as stop valves, flowing valves, core heads, etc., tested the tightness of joints and conducted a complex of geophysical studies to ascertain the serviceability and reliability of the wells.
“The performed repair works allowed increasing the calculated productivity of the wells by 11%, improved safety and reliability of gas storage in UGSF, stability of its withdrawal and injection in the future”, – summed up in “Ukrtransgas”.
