UNB started production at well # 48 of Sakhalinske field
Ukrnaftoburinnya (UNB) has completed well # 48 with a depth of 4850m with an initial flow rate of natural gas of 200 thousand cubic meters, and condensate - 20 tons. The news informed by the press service of the company.
The well was drilled with the Uralmash 4E drilling rig, equipped with triplex pumps and a state-of-the-art mud cleaning system, the report said.
The company also noted that the drilling company Ukrburservice was the general contractor in the construction of the well. In the process of drilling and casing the contractor used products and services of wellknown foreign manufacturers of equipment and service companies, namely: Voestalpine Tubulars GmbH & Co KG, Smith Bits, Weatherford, LGH Inc.
A commercial inflow of gas and condensate was obtained when testing the B-22 horizon of the specified well. The productive horizon was cased with a slotted liner without cementing, which allowed to avoid the negative impact on the reservoir.
“We are continuing to implement the drilling program for this year and plan to drill another well in the near future. Due to the intensive drilling program with the use of new technologies and the involvement of professionals of the international level, we expect that the production in 2019 will exceed the rates of last year by at least 30%,” said MykhailoBakunenko, Chairman of the Board of Ukrnaftoburninnia.
