First, vertical drilling is carried out before the well is diverted in a south-westerly direction in order to reach the defined drilling target at a depth of around 1,700 meters in the Pechelbronn strata. The oil well that Rhein Petroleum wants to develop is in the immediate vicinity of the structures from which the company has been producing domestic oil on a permanent basis since 2018.
The borehole, approved and monitored by the Darmstadt regional council, consists of several tubes nested inside one another like a telescope. Each individual pipe, which decreases in diameter downwards, is firmly enclosed with high-density special cement, so that the uppermost area carrying drinking water is protected by several layers of steel and cement. After reaching the drilling target, borehole geophysical measurements are taken at depth and a production test is carried out
