Heidelberg/Riedstadt – In the coming days, a drilling rig with a tower around 35 meters high will once again be on display at the Rhein Petroleum drilling site in Riedstadt-Goddelau. The Heidelberg company is installing an approximately 100 meter long branch in the lowest section of the existing “Schwarzbach 2” borehole. This ends a few meters further west in the same structure as the existing borehole.
“The tested production rates from the existing well do not do justice to the proven petroleum reserves in the Pechelbronn layers. The drilling fluid, which consists primarily of starch, has too tightly sealed the rock pores through which the oil flows into the production line in the immediate vicinity of the borehole. Therefore, the expected quantities of oil are not coming through,” explains Rhein Petroleum managing director Peter Appel. That's why a new entrance is now being laid at a depth of around 1,600 meters. He makes it clear: “The natural porosity, i.e. the permeability of the rock, is good. We are confident that the new short branch line at the end of the well will result in a flow rate that reflects the quality of the reservoir we encountered last August,” emphasizes Appel.
The drilling rig now in use is identical to the rig that was also used in the summer of 2023. The system is expected to be delivered and set up gradually in the first week of May. The actual drilling follows immediately and takes about two days. “The existing well will be used unchanged up to a depth of around 1,600 meters and will receive a newly drilled branch from there,” explains the Rhein Petroleum managing director. Immediately after the end of the drilling, the test production is prepared, including inserting the delivery pump. Appel: “Due to the excellent reservoir properties and the known data, we continue to be convinced that ‘Schwarzbach 2’ can produce significant quantities of high-quality domestic crude oil.” Heidelberg, April 24, 2024
