Abstract: A removable apparatus having a core holder body and a core sample assembly fitted inside the core holder body is disclosed. The core sample assembly includes a core sample and a sleeve fitted around the core sample. A first flanged stopper and a second flanged stopper are positioned at opposite axial ends of the core holder body. A flow path is formed through the first and second flanged stoppers and interfaces at opposite end surfaces of the core sample. Also provided are an assembly and a system comprising the removable apparatus for use in oilfield applications. Further, a method of testing a property of a fluid using the removable apparatus is provided.

Abstract: A method includes determining a critical micelle concentration (Ccm assumed) of a sample with an unknown concentration (Cs) of a surfactant based on an assumed surfactant concentration (Cassumed) of the sample, providing a benchmark solution with a known concentration of the surfactant, determining an actual critical micelle concentration (Ccm) of the surfactant from the benchmark solution, and calculating the unknown concentration (Cs) of the surfactant in the sample from the following equation: Cs=Ccm/(Ccm assumed/Cassumed).

Abstract: Techniques for analyzing a sample include preparing a sample; circulating a gel solution through the sample to saturate the sample; scanning the saturated sample with a nuclear magnetic resonance (NMR) system to determine two or more NMR values of the saturated sample; determining a permeability of the saturated sample based, at least in part, on the two or more NMR values of the saturated sample; aging the saturated sample; scanning the aged sample with the NMR system to determine two or more NMR values of the aged sample; determining a permeability of the aged sample based, at least in part, on the two or more NMR values of the aged sample; comparing the determined permeability of the saturated sample against the determined permeability of the aged sample; and based on the compared permeabilities, determining a gel solution syneresis rate.

Abstract: 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.
