  • Patent number: 12116889
    Abstract: The disclosure presents processes to determine a first formation fluid-second formation fluid boundary from one side of the boundary utilizing a formation tester tool. For example, the formation tester can be utilized in a borehole to determine an engagement point with a subterranean formation and determine one or more, or a combination of, injectable fluids to inject into the subterranean formation. Sensors coupled to the formation tester can measure the rebound pressure of the injected fluids. In some aspects, the fluid density of the collected fluid can be measured. The measured pressure changes and other collected data, can be utilized to determine a first formation fluid-second formation fluid boundary parameter. Other characteristic parameters can also be determined such as wettability parameters, porosity parameters, and capillary effects parameters. The formation tester can collect a core sample and an analyzation of the core sample can be utilized to determine the characteristic parameters.

  • Patent number: 12091969
    Abstract: A downhole sampling tool includes a tool body defining an opening therein for drawing a formation fluid into the downhole sampling tool. At least one sampling vessel is carried in the tool body and is operatively coupled to the opening to receive the formation fluid therein. A closure member is selectively engageable with the opening to prohibit flow of the formation fluid through the opening, and a biasing mechanism is operably coupled to the closure member. The biasing mechanism biases the closure member into engagement with the opening and is responsive to an increase in hydraulic pressure on the exterior of the sampling tool to a predetermined threshold pressure to permit movement of the closure member away from the opening and permit flow of the formation fluid through the opening and into the sampling vessel.
