Latest Patents
Among his latest inventions, Helms developed a method for the determination of the water cut of a multiphase flow. This technique employs microwave energy in the 10 GHz range transmitted through a test call with a known geometry. The attenuation and phase shift of the microwave energy are measured to derive the wave number of the microwaves in the unknown fluid. Subsequently, the water fraction of the fluid is calculated using Hannai's equation based on the determined wave number and the geometry of the test call.
In addition, he patented a method for determining water cut and gas fraction in oil, water, and gas streams. This process involves taking numerous small volume samples at a high frequency from a multiphase fluid stream, enabling precise evaluation of oil, water, and gas fractions. Rapid fluctuations from an all-liquid curve signal the presence of gas in the fluid, showcasing the effectiveness of his innovative approach.
