Russia: Offshore Drilling Rosneft Completes Drilling of Maiden Exploration and Appraisal Well Offshore Black Sea
A unique carbonate structure including a fractured reservoir of potential hydrocarbons was discovered while drilling the well. This makes Rosneft confident about discovering large oil and gas fields in the Russian Black Sea waters.
Moscow/Russia – Rosneft, Russia’s oil giant has completed the drilling of the first super deep exploration and appraisal well Maria-1 on the Zapadno-Chernomorskaya license area offshore the Black sea. The water depth at the drilling site reaches 2109 meters. The actual well depth is 5265 meters. A unique carbonate structure with 300 meters gross interval was discovered on drilling this well.
This structure constitutes a fractured reservoir that is highly likely to contain hydrocarbons. These results instill confidence in the possibility to discover large oil and gas fields in the Russian Black Sea waters. The company plans to conduct a thorough geological processing of the materials and to continue exploration and appraisal works on the license areas.
Rosneft carries out this project on drilling the first exploration well on the Zapadno-Chernomorskaya license area together with Eni, Rosneft’s strategic partner. Drilling preparation included 4000 running kilometers of 2D seismic survey and over 3000 square kilometers of 3D seismic survey as well as comprehensive engineering and geological studies.
