Publication number: 20230080236Abstract: A method and a system to determine a gelation time of a substance in a container is disclosed. The system includes a container, a bubble generator arranged at a first end of the container, and a bubble sensor arranged at the second end of the container. The container holds a substance having a surface adjacent the second end. The bubble generator is configured to generate a bubble at the first end. The bubble sensor is configured to sense the bubble at the surface of the substance. The method includes releasing a gas into a first end of the container such that the gas bubbles rise from the first end of the container to a second end of the container, sensing the released bubbles, determining an absence of a bubble released by the bubble generator at the bubble sensor, and determining a gelation time based on a number of detected bubbles.Type: ApplicationFiled: September 15, 2021Publication date: March 16, 2023Inventors: Mohanad M. Fahmi, Abdulkareem AlSofi

Patent number: 11333491Abstract: A contact angle measurement system includes a housing that can hold a volume of a first fluid having a first density, an adjustable rock sample holder positioned within the housing, a fluid dropper attached to the housing, an image capturing a device, and a computer system. The holder can support a rock sample. An orientation of the holder relative to the housing is adjustable such that an outer surface of the rock sample is at a non-zero angle relative to a lower wall of the housing. When the orientation of the holder relative to the housing is such that the outer surface of the rock sample is at the non-zero angle relative to the lower wall, the fluid droplet traverses the outer surface of the rock sample. The image capturing device can capture images of the fluid droplet as the fluid droplet traverses the outer surface of the rock sample.Type: GrantFiled: April 2, 2020Date of Patent: May 17, 2022Assignee: Saudi Arabian Oil CompanyInventors: Amar Alshehri, Abdulkareem AlSofi

Patent number: 10788410Abstract: A polymer is flowed through a slim tube including porous media until steady state is achieved. A temperature of the porous media with the polymer is adjusted to emulate a reservoir temperature. A slug of a gel solution is flowed through the porous media in the slim tube. The gel solution includes the polymer and a crosslinker. The gel solution is configured to at least partially solidify at the temperature. Multiple pressure drops across the porous media in the slim tube are measured at corresponding locations along a length of the slim tube while the slug flows through the porous media in the slim tube. The slug at least partially solidifies within the slim tube, causing an increase in pressure. A location of gelation of the slug of gel solution within the slim tube is determined based on the increase in pressure.Type: GrantFiled: December 19, 2018Date of Patent: September 29, 2020Assignee: Saudi Arabian Oil CompanyInventors: Jinxun Wang, Abdulkareem AlSofi, Amar Jaber M.
