  • Publication number: 20210372947
    Abstract: An x-ray-based borehole fluid evaluation tool for evaluating the characteristics of a fluid located external to said tool in a borehole using x-ray backscatter imaging is disclosed, the tool including at least an x-ray source; a radiation shield to define the output faun of the produced x-rays into the borehole fluid outside of the tool housing; at least one collimated imaging detector to record x-ray backscatter images; sonde-dependent electronics; and a plurality of tool logic electronics and power supply units. A method of using an x-ray-based borehole fluid evaluation tool to evaluate the characteristics of a fluid through x-ray backscatter imaging is also disclosed, the method including at least producing x-rays in a shaped output; measuring the intensity of backscatter x-rays returning from the fluid to each pixel of one or more array imaging detectors; and converting intensity data from said pixels into characteristics of the wellbore fluids.

  • Patent number: 10253618
    Abstract: An apparatus and associated method for obtaining a three-dimensional representation of a target object within a fluid-carrying conduit, such as a hydrocarbon exploration or production well, using high energy photons is provided. The representation is essentially a three-dimensional image that achieves visualization of the shape of the target object despite the intervening opaque fluids located between the imaging tool and the object. In one specific though non-limiting embodiment, a narrow, pencil-shaped beam of radiation is scanned in coordination with a similarly narrow detector field-of-view in order to sample the radiation-scattering properties of only a small volume of material at any given time. The result is a clearer visualization with a greater viewing depth.

  • Patent number: 8899324
    Abstract: A method for sampling fluid in a subterranean formation includes reducing a viscosity of the fluid, pressurizing a portion of the subterranean formation, and collecting a fluid sample. Specifically, a viscosity of the fluid in a portion of the subterranean formation is reduced and a portion of the subterranean formation is pressurized by injecting a displacement fluid into the subterranean formation. A sample of the fluid pressurized by the displacement fluid is then collected.
