Systems and Methods for Identifying Two or More Charges into Reservoir Using Downhole Fluid Analysis
Publication number: 20240151139Abstract: Systems and methods for identifying a likelihood that a reservoir of a geological formation received a secondary charge of hydrocarbons of relatively very different thermal maturity of composition are provided. One method includes positioning a downhole acquisition tool in a wellbore in a geological formation and testing one or more fluid properties of the formation fluid. Data processing circuitry may identify whether a relationship of the one or more fluid properties exceeds a first threshold that indicates likely asphaltene instability. When this is the case, data processing circuitry may be used to model the geological formation using a realization scenario in which multiple charges of hydrocarbons of substantially different thermal maturity or substantially different composition, or both, filled a reservoir of the geological formation over geologic time.Type: ApplicationFiled: January 8, 2024Publication date: May 9, 2024Inventors: Hadrien Dumont, Vinay K. Mishra, German Garcia, Li Chen, Thomas Pfeiffer, Soraya S. Betancourt Pocaterra, Jerimiah Forsythe, Andrew Emil Pomerantz, Youxiang Zuo, Oliver C. Mullins -

Patent number: 11808150Abstract: This disclosure relates to a separating a fluid having multiple phases during formation testing. For example, certain embodiments of the present disclosure relate to receiving contaminated formation fluid on a first flow line and separating a contamination (e.g., mud filtrate) from the formation fluid by diverting the relatively heavier and/or denser fluid (e.g., the mud filtrate) downward through a second flow line and diverting the relatively lighter and/or less dense fluid upward through a third flow line. In some embodiments, the third flow line is generally oriented upwards at a height that may facilitate the separation of the heavier fluid from the relatively lighter fluid based on gravity and/or pumps.Type: GrantFiled: May 16, 2022Date of Patent: November 7, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Thomas Pfeiffer, Ashers Partouche, Kai Hsu, Simon Edmundson

Patent number: 11806185Abstract: A computer-implemented method is for determining at least one main acquisition parameter determining a dose of x-rays to be emitted from an x-ray emitter during image acquisition using an x-ray emitter and an x-ray detector. A first image data of a first preparatory image is evaluated to determine if a repeat condition is fulfilled and/or to determine the main acquisition parameter and/or at least one second preparatory acquisition parameter. The first preparatory image is acquired by the x-ray detector using at least one first preparatory acquisition parameter to control the x-ray emitter. In all cases or when the repeat condition is fulfilled, the main acquisition parameter is determined depending on second image data of a second preparatory image, acquired by the x-ray detector after the first preparatory image while at least one second preparatory acquisition parameter is used to control the x-ray emitter.Type: GrantFiled: January 7, 2021Date of Patent: November 7, 2023Assignee: Siemens Healthcare GmbHInventors: Andre Gebhardt, Sebastian Glawion, Thilo Hannemann, Carsten Illenseer, Daniel Lerch, Thomas Pfeiffer, Stefan Schaffert, Peter Scheuering, Bastian Schmidt, Thomas Weber, Wei He, Sven-Martin Sutter, Zhi Ming Yang
