Juschno-Sachalinsk, Oktober 1 - Neftegaz.RU. As part of its exploration campaign, Rosneft has successfully completed the drilling of the 1st prospecting and appraisal well at the Vostochno-Pribrezhny license block on the shelf of Sakhalin Island, resulting in the discovery of a new oil field.
As a result of drilling, the measured depth was 3,047 m; the vertical deviation was 1,450 m. A well design that provided for drilling 2 holes with S-shaped paths was developed for optimal discovery of all intended targets in the course of drilling in difficult geological conditions. A set of geophysical studies in the open hole confirmed the oil saturation of productive formations.
In the course of further development of the project, decisions will be made on the timing of the commissioning of the new field. The 1st well drilled in the licensed area at the moment confirms the forecast made earlier by the company’s geologists for the resource potential of the entire area of 11 million tonnes of oil equivalent.
