Title: Konrad Siemer: Innovator in Mineral Oil Production
Introduction
Konrad Siemer is a notable inventor based in Kassel, Germany. He has made significant contributions to the field of mineral oil production, holding a total of 4 patents. His innovative approaches have the potential to enhance the efficiency of oil extraction processes.
Latest Patents
One of Siemer's latest patents is a process for producing mineral oil from underground mineral oil deposits. This process increases the mineral oil yield by blocking highly permeable regions of the mineral oil formation. It involves the separate injection of at least one acidic formulation containing water-soluble Al(III) salts and a formulation comprising urea or urea derivatives into the deposit. These formulations do not mix until they are within the deposit, where they form highly viscous gels under the influence of the deposit temperature. This method is particularly useful in the final stages of deposit development, especially when watering out in production increases, and after steam flooding of the deposits.
Another significant invention by Siemer is a device and method for well stimulation. This invention features a heat generator for well stimulation, which includes a tubular fuel vessel with two or more mutually separated, closed segments arranged in longitudinal succession. Each segment is at least partly filled with fuel, and at least one igniter is used to ignite the fuel in one of the segments. The design allows the fuel in a subsequent segment to be ignitable due to the heat generated from the burnoff of the fuel in the preceding segment. This innovative heat generator is aimed at improving well stimulation processes.
