Field facts

More than 95% of the natural gas produced in Germany is found in Lower Saxony. Neptune participates in several partner-operated gas fields. Among them are the DEA-operated Hemsbünde and Bötersen fields, two of the ten most productive natural gas fields in the country. ExxonMobil is joint operator at Bötersen, and operates the Hamwiede and Walsrode/Idsingen gas-producing fields. The Fehndorf gas field is operated by Wintershall. Neptune’s 2018 share of partner-operated gas production was 610 kboe.

Oil production interests in the state include a 50% participation in Rühlermoor, the largest oil field in mainland Germany. Rühlermoor produces a highly viscous crude. This makes it tough to extract. Production started in 1949, but only about a third of its 680 mmboe reserves have so far been recovered. Neptune is increasing recovery rates with thermal enhanced oil recovery, a steam injection process that improves oil flow properties by reducing viscosity.

ExxonMobil operates Rühlermoor and the Georgsdorf, Annaveen and Meppen-Schwefingen oil fields.

Produced oil is transported by pipeline to the BP refinery in Lingen. The pipeline network is currently being modernised to ensure the long-term sustainability of oil production in the area. Neptune’s 2018 share of partner-operated oil production in the region was 868 kboe.
