Neptune Energy began drilling the Ofelia well


Inspenet, October 5, 2023.

Neptune Energy reported that it has begun drilling operations at the Ofelia appraisal well, located in the Norwegian North Sea region. The discovery of Ofelia took place in August 2022 and is located approximately 14 km north of the Gjøa field, which is operated by Neptune.

First estimates indicate that the recoverable volume is in a range of 2.5 to 6.2 million m 3 or equivalent to 16 to 39 million barrels of oil (mmboe). The main purpose of the new well is to carry out a complete evaluation of the hydrocarbon discovery in the Ofelia Agat formation.

In addition, a secondary evaluation of the gas-laden zone in the shallower Kyrre Formation will be carried out. Neptune Energy’s subsurface director in Norway, Steinar Meland, commented: ” The Ofelia discovery fits perfectly with our strategy of focusing on opportunities within core areas close to existing infrastructure .”

“The Ophelia discovery could be linked to the Neptune-operated Gjøa platform and produce with less than half the average carbon intensity of Norwegian continental shelf fields 1.”

The goal of Neptune Energy

The Lower Cretaceous Agat Formation, located at a depth of approximately 2,530 meters, is the main objective of this deposit . The well in question, identified as 35/6-4 S, is being drilled by the Deepsea Yantai semi-submersible platform, which is owned by CIMC and operated by Odfjell Drilling.

The partners involved in this operation are Neptune Energy (40% stake and operator), Wintershall Dea (20%), Pandion Energy (20%), Aker BP (10%) and DNO (10%).
