Germany’s largest and most productive oil field
The oil deposits under the Mittelplate area off the western coast of Schleswig-Holstein are quite substantial. In addition to the 27 million mt of crude oil that have already been produced, according to information available today there still are some 20 to 25 millions mt in technologically and commercially recoverable reserves.
As a result, not only is Mittelplate the German oil field with the highest production volumes; with just the half of the national oil reserves, it also represents one of the few proven reservoirs with a future.
The initial production rates of around 200,000 mt of crude oil annually have steadily increased over the last years. In 2011 more than 1.4 million mt of crude oil have been prodcuced. The dynamic development of geophysical processes and drilling technology in recent years has opened up new horizons for efficient drilling and production methods, making it possible for oil production to be continually optimized. The annual production is a significant contribution to domestic oil production, and hence to the stability of the energy supply in the Federal Republic of Germany.
Crude oil production takes place in a combined offshore and onshore operation. The western sections of the reservoir have been developed from the Mittelplate Drilling and Production Island located seven kilometers offshore. Since early summer of the year 2000, land-based production from the eastern section of the oil field has been conducted via extreme extended-reach wells.
