Ukrnafta has launched another high-rate well in the east of Ukraine using its own drilling rig. 

During the drilling process, the Company used in-house developments: the Industrial Chemistry and Core Analysis Department developed a drilling fluid based on a basic recipe, that was used to a depth of 2,013 metres.
