Canada-based Valeura Energy said that it has recompleted the Yamalik-1 well in the Thrace Basin of Turkey where it has confirmed significant amount of condensate.

The well was successfully recompleted by drilling out the plugs and installing production tubing to allow for a long-term production test on a comingled basis. The well began producing gas and condensate on September 12, 2018.

At the end of 24 hours of continuous production, the flow rate was 2.53 mmcf/d through a 20/64″ choke with a wellhead pressure of 2,535 psi.

Four days into the production test the well was beginning to show signs of stabilized flow, with gas rates currently at 1.40 mmcf/d. The well is still in clean up with an average frac water return rate of 870 bbls/day and the amount of frac water recovered is estimated to be 33%.

Initial analysis on the composition of the water indicates that this is primarily frac fluid. The average condensate rate over the first 4 days of production is 49 bbl/mmcf.

In the coming days, Valeura expects to begin producing the well through its infrastructure. Long-term production data from this well is an important part of the ongoing appraisal program of the Basin Centered Gas Accumulation (“BCGA”).

Valeura Energy president and CEO Sean Guest said: “I am delighted to once again be able to announce flow rates from the Yamalik-1 well, and to confirm the presence of a significant amount of condensate.

“We are all pleased with the initial flow rate given that this is our first real fracing program in this play, albeit a relatively modestly-sized 8-stage frac to test selected sands comprising less than half of the interpreted net pay in Yamalik.

“Long-term production data will help us to better determine the flow potential of this reservoir, and the production of gas and condensate will provide an immediate increase to our revenues.”

The Company is preparing to spud Inanli-1, the first of three appraisal wells, in the next month with well results expected in late Q4 2018. Key equipment, including a drilling rig, is being mobilized to the drilling location, which is approximately 6 km to the north-east of the Yamalik-1 discovery well.
