  • Publication number: 20210381363
    Abstract: A system includes a pressure transient analysis test tool with flow analysis components and at least one pressure sensor. The pressure transient analysis test tool collects pressure measurements for at least one target position in a borehole as a function of time and fluid flow rate. The system also includes at least one processor that receives saturation analysis results and porosity analysis results related to each target position. The processor estimates relative permeability values based at least in part on the pressure measurements, the saturation analysis results, and the porosity analysis results.

  • Patent number: 10982539
    Abstract: A formation-tester tool may be positioned downhole in an openhole wellbore. The formation-tester tool may suspend proppant in fracturing fluid located in a chamber of the formation-tester tool. The formation-tester tool may generate a test fracture in an uncased wall of an area of interest of a subterranean formation adjacent to the openhole wellbore and inject the fracturing fluid and the proppant toward the uncased wall and into the test fracture. The formation-tester tool may retrieve a fluid sample from a reservoir within the area of interest of the subterranean formation by creating a drawdown pressure in the test fracture.
