Well R-103 is the first of a series of horizontal wells designed to develop and further appraise the significant gas resources of the deep tight gas Rudenkovskoye reservoirs.
Well R-103 flowed at a stabilized rate of 8.1mmcfd of gas and 18bpd of condensate through a 85/64" choke with a flowing wellhead pressure of 930psi over the final eight hour period of a multi-rate test.
The well has been tied back to the main field processing facility with an 8km flow line and will be placed on production, JFX said.
Well R-103 reached a measured depth TD of 4,641m in the Devonian sandstone with an openhole section in the reservoir of 1,026m, making it the longest horizontal well drilled in Ukraine to date.
The well was drilled using the Skytop N-75 drilling rig. The rig has now moved to well M-169 to drill a horizontal well in the Devonian reservoir of the Molchanovskoye North Field.
It will then return to the Rudenkovskoye Field in early 2011 to drill horizontal well R-105 in the Devonian sandstone, an offset to well R-103, followed by well R-104, which will target the Visean reservoir sands present in the northern field area.
