IPC: C07C315/02
Filed: 1998-09-18
Abstract: The organic compound is oxidized in the form of a solution by addition of a peroxidic oxidizing agent containing at least two linked oxygen atoms (-O-O-). For this purpose, a starting material A comprising the organic compound and a starting material B comprising the peroxidic oxidizing agent are continuously mixed with one another, then the liquid reaction mixture is fed to a microreactor (1) having an abundance of parallel reaction channels (4') and adjacent cooling channels (3') and thus simultaneously divided among the reaction channels (4'). The cooling channels (3') are charged with a coolant here to remove the heat generated in the microreactor (1) by the exothermic oxidation reaction in the reaction channels (4'). The microreactor (1) used for this purpose is characterized in that the largest channel dimension a of the reaction channels (4') perpendicular to the flow direction of the adjacent channels is < 1000 µm, preferably < 500 µm, and the lowest wall thickness b between the reaction channels (4') and the cooling channels (3') is < 1000 µm, preferably < 100 µm. A microreactor having a plurality of serial stages (10a... 10n) whose reaction channel cross-sectional areas increase in the flow direction, has proved particularly suitable. The process is preferably used for the oxidation of organic sulphides, hydrogen peroxide being used as oxidizing agent.

Title: Quantification of drilling mud cuttings characteristics as a measure of relative permeability
Inventor: ZAMFES KOSTA
IPC: E21B49/00
Filed: 1998-12-16
Abstract: A method is provided for establishing semi-quantitative values indicative of porosity and permeability of a formation during drilling.
