His work focuses on enhancing the accuracy and efficiency of determining formation fluid properties and pressures.

Latest Patents

One of Hemsing's latest patents is titled "Real-time determination of formation fluid properties using density analysis." This invention evaluates formation fluid with a downhole tool disposed in a borehole. A plurality of possible constituents is defined for the formation fluid, and constraints are established for these constituents. The constraints can include boundary constraints and constraints on the system's dynamics. The formation fluid is obtained from the borehole with the downhole tool over several time intervals, and the density of the obtained formation fluid is measured at these intervals. To evaluate the fluid composition, a state probability distribution of the possible constituents is computed recursively, allowing for the probabilistic inference of formation properties such as contamination level and gas-to-oil ratio (GOR).

Another significant patent is the "Autonomous formation pressure test process for formation evaluation tool." This invention involves a formation tester that places an isolation device in fluid communication with a formation to determine formation pressures. The tester's controller autonomously controls the operation using a pressure pre-test process. It measures drawdown pressure and interval as the tester draws down pressure in a flowline coupled to the probe. If the drawdown pressure indicates a dry test, the process is aborted. Otherwise, the controller measures buildup pressure and interval, allowing for a comprehensive evaluation of formation pressures.
