Petroceltic International PLC’s Melrose Resources Romania BV subsidiary has spudded a wildcat on the Cobalcescu South prospect in the Black Sea offshore Romania.
The wellbore is to follow an S-shaped trajectory in order to optimally penetrate two primary reservoir targets in Miocene Upper Pontian and Lower Pontian sandstone. The drillsite is in the southwest corner of Block EX-28 in 90 m of water 170 km northeast of Constanta.
Petroceltic was awarded a 40% working interest in the Est Cobalcescu (Block EX-28) and Muridava (Block EX-27) concessions and operates both blocks. It holds Est Cobalcescu in partnership with Beach Petroleum SRL and Petromar Resources SA 30% each.
Petroceltic has carried out a substantial work program, including the acquisition and processing of 1,930 sq km of high-quality 3D seismic. Ongoing structural, stratigraphic, and attribute interpretation of the seismic dataset has yielded a significant prospect inventory composed primarily of biogenic gas prospects, with some potential oil prospects also identified.
In parallel with the subsurface work, preparations for a multiwell drilling campaign have progressed with the selection of drilling locations, well planning, permitting, and site survey work, and the contracting of the GSP Prometeu jackup.
An exploratory well on the adjacent Muridava license is to follow the drilling of Cobalcescu South.
