JKX Oil & Gas has completed development well NN-80, which has been placed on production, in the Novo-Nikolaevskoye Field in Ukraine, the company said in a news release.
Following clean-up, well NN-80 produced at a stabilized rate of 4.98 MMcf/d and 51 bbl/d condensate through a 1-in. choke with a flowing wellhead pressure of 587 psi during the multi-choke test sequence. The well has now been placed on production.
Well NN-80 was drilled to a measured depth of 1,794 m (5,886 ft) and targeted at the primary upper V15 Visean sandstone reservoir, the release said. During drilling, encouraging shows also were encountered in the lower V15 sandstone which warranted deepening the well by some 50 m (164 ft) to allow completion and testing of the lower reservoir at a later stage.
Well NN-80 was drilled on a seismic amplitude anomaly identified following re-processing and interpretation of the latest 3-D seismic data over the Poltava licenses, the release said. The N-75 Skytop rig has now left the Novo-Nikolaevskoye Field to drill appraisal well IG-141 on the northern flank of the adjacent Ignatovskoye Field.
