Ukrgasvydobuvannya has carried out workover of the appraisal well that was drilled more than 50 years ago. The daily flow rate after the workover is more than 340 thousand cubic meters of natural gas.
The well was first commissioned in the late 60s of the last century with a flow rate of about 1 million cubic meters per day. The well has been producing for more than 40 years and yielded more than 4 billion cubic meters of gas.
- Last year, we received the largest production over the past 4 years by carrying out well workovers, and this is 20% higher than the pre-war production in 2021. Our specialists are continuously working on reviewing and analyzing the old wells that can be returned to production by virtue of more enhanced technical capabilities than those that were decades ago, - Oleg Tolmachev, acting CEO of Ukrgasvydobuvannya, comments.
The well has been pending for abandonment for a long time, but last year the UGV specialists conducted a detailed analysis of the well, reviewed its technical and geological risks and made the decision to re-enter the well by performing the workover.
Fishing operation performed by UGV-Service in the well, and geophysical data interpretation made it possible to identify the upside potential of the previously unpenetrated formations. After the perforation, the well produces at a high flow rate.
