Well workover in northern Ukraine ensures flow rate of over 60,000 cm of gas per day

MOSCOW. Nov 21 (Interfax) - The Ukrnafta company has carried out a well workover in northern Ukraine that ensured a natural gas flow rate of over 60,000 cubic meters per day, as well as reached new prospects for additional exploration of the field.

"The preliminarily evaluated flow rate following the well workover is more than 60,000 cubic meters of natural gas per day," Ukrainian media quoted Ukrnafta CEO Sergei Koretsky as saying on the company's website.

A team of the well workover has conducted a geophysical survey to determine the saturation of the new deposit and disconnected the depleted lower horizon, the company said.

Drilling operations were carried out at a depth of between 2,317 and 2,322 meters to connect the deposit to the well, after which the company started development of the well.

The deposit is two square kilometers in size, 35.4 meters thick, with a productive thickness ranging from two to seven meters. It was initially evaluated at 199 million cubic meters of gas and 70,000 tonnes of condensate. These reserves have not been commercially developed.

"Now, having achieved good results following the well workover, we can confidently say that there is a resource, that is why the company plans to develop it," Ukrnafta said.

Ukrnafta is the largest oil company in Ukraine, which operates a national network of 537 gas stations, of which 456 are operational.

The majority shareholder of Ukrnafta is Naftogaz of Ukraine with a 50% plus one share stake.
