    摘要: Example methods and apparatus to perform pressure testing of geological formations are disclosed. A disclosed example method comprises positioning a testing tool in a wellbore formed in the geological formation, sealing a sample interval around the testing tool, sealing a first guard interval around the testing tool and adjacent to the sample interval, reducing a first pressure in the sample interval, reducing a second pressure in the first guard interval, maintaining a volume of a first chamber fluidly coupled to the sample interval during a time interval, and measuring a plurality of pressure data for a fluid captured in the first chamber during the time interval.

    摘要: Cooling apparatus and methods for use with downhole tools are described. An example apparatus includes a cooling apparatus for use with a downhole tool. The cooling apparatus includes a flow passage having an inlet and an outlet. The outlet is configured for fluid communication with a wellbore and the inlet is spaced from the outlet. The cooling apparatus also includes a pump configured to convey at least one of a drilling fluid or a formation fluid between the inlet and the outlet. Additionally, the cooling apparatus includes a heat exchanger coupled to a surface adjacent the flow passage and a component of the downhole tool to convey heat from the component to the cooling fluid.

    摘要: Methods and apparatus to apply axial force to a packer in a downhole tool are described. In one described example, an apparatus to apply an axial force to an inflatable packer associated with a downhole tool includes a sleeve slidingly coupled to a body of the downhole tool and an end of the packer. An inner portion of the sleeve is sealed against the body of the downhole tool to form a chamber, and the chamber is fluidly coupled to a pump associated with the downhole tool to receive a pressurized fluid to cause the sleeve to apply an axial force to the packer.
