Based on initial production tests, the well reported flow rates of up to 2,800 barrels of oil equivalent per day (boepd).
Neptune expects the Adorf Z16 well to increase its production to nearly 4,000boepd.
After drilling to a final depth of 5,378m in the Carboniferous formation last year, the well was connected to a processing plant located at the project site for treating natural gas.
Neptune Energy Germany managing director Andreas Scheck said: “The Adorf Carboniferous field is one of the most exciting discoveries in Germany in recent years. It is one of Neptune’s most promising developments in Germany, and demonstrates our desire to grow our business here.”
Located in the municipality of Hoogstede, North Western Germany, the Adorf Carboniferous gas field was brought into production in October 2020.
The company now plans to drill the third well at Adorf in Q2 2022. The construction of a new well pad is already under way.
As an independent global E&P company, Neptune Energy has operations across the North Sea, North Africa and Asia Pacific regions.
Last year, the company had a production of 142,000 net barrels of oil equivalent per day.
It operates six oil fields and ten gas fields in Western Germany.
The firm considers the Bramberge, Adorf/Scheerhorn, Ringe, and Adorf Carboniferous fields to be among the most productive.
In November 2021, the owners of the Neptune Energy Group were reportedly looking to sell the firm in a deal that could be worth up to $5bn.
