  • Patent number: 11655709
    Abstract: The disclosure presents an apparatus and system to allow for multiple downhole sensors to be oriented at varying azimuthal angles to collect reservoir data across varying azimuthal directional arcs. In one aspect, two sensors can be attached to a downhole tool system, one being oriented azimuthally 90° different than the other sensor. In other aspects, a method and system are presented to utilize the collected reservoir data to compute a porosity anisotropy and permeability parameters. These parameters can be utilized to further derive reservoir characteristic parameters, such as a permeability ellipsoid that can identify the primary axis of drainage of the reservoir and the minimum axis of drainage of the reservoir. The derived reservoir characteristic parameters can be utilized to modify a well system operation plan, such as to improve the well system production over a time period.

  • Patent number: 10883365
    Abstract: A downhole probe assembly is employed in a wellbore to mitigate the effects of hoop stress on the operation of the probe assembly. A shaped head is driven radially into the geologic formation surrounding the wellbore. A sensor and/or fluid ports may thereby be delivered to a radial depth in the geologic formation beyond a hoop stress regime associated with the wellbore. In this manner, analysis and fluid communication with the geologic formation may not be hindered by the hoop stress regime surrounding the wellbore. The probe assembly may be employed in microfracture tests in which fluid is injected into geologic formation through mechanical fractures created by the shaped heads extending through the hoop stress regime. The fluid injected through the hoop stress regime may more readily interact with the geologic formation, and subsequent analysis of the injected fluids may yield more relevant information about the geologic formation.
