Following the results of tests on the Upper Visean V-18 zone, the construction of production facilities and a pipeline to tie the well into a sales point has now been completed. This is said to be the first occasion that the V-18 horizon has proved commercial in the Zagoryanske license.
Based on analysis undertaken by the Ukrainian State Geological Exploration Institute (USGEI), the well is expected to average around 35mcm/day gas and 15t/day condensate. After a period of stable production further analysis will determine whether higher flow rates of up to 50mcm/day can be sustained.
The extent of the V-18 reservoir in the Zagoryanske 3 area has still to be fully mapped and confirmed, but it is anticipated that additional wells will be required to fully exploit this accumulation.
Although the current focus is on the V-18 discovery, the report from the USGEI also points out that, despite the previously announced unsuccessful tests on the Tournasian and Lower Visean intervals of the Zagoryanske 3 well, it could also produce at commercial rates from those intervals by utilizing proper test procedures, an appropriate completion string and a series of stimulation treatments.
