The NN-71 in the Ukrainian NovoNikolaevskoye field has been successfully recompleted and is back in operation, announced JKX Oil and Gas.
The nearby V15 field was closed earlier this year for restructuring, after 3D seismic scanning at the time revealed an amplitude anomaly, which was corrected by accessing the NN-71 well using the returned TW-100 rig.
Following a recent three stage test, the well is producing at a stabilised rate of 4.3 MMcfd of gas and 342 bpd of condensate.
The results indicate the reservoir still has good pressure support despite producing hydrocarbons for more than 28 years, JKX claim.
“The success of this recompletion indicates that the continued efforts by our subsurface teams in Poltava and London to update our data and understanding in these complex structures can yield valuable results,” said Dr Paul Davies, JKX chief executive.
