  • Patent number: 11066905
    Abstract: A method for modelling saturation in a reservoir, comprising: obtaining capillary pressure data representing capillary pressure in the reservoir; obtaining permeability data representing permeability in the reservoir; determining a number of pore throats represented by the capillary pressure data; creating hyperbolic tangents based on the capillary pressure data equal in number to the number of pore throats; combining hyperbolic tangents to create a curve to fit the capillary pressure data and to define hyperbolic tangent parameters; combining at least one of the hyperbolic tangent parameters with the permeability data to define a saturation height function; modelling a saturation in the reservoir using the saturation height function; and displaying the saturation model based on the saturation height function.

  • Patent number: 10787902
    Abstract: A system and method for correcting capillary pressure curves includes creating a capillary pressure curve using multiple linked hyperbolic tangents, determining a closure correction pressure cutoff of the capillary pressure curve, and correcting the capillary pressure curve. The correction may include normalizing the capillary pressure curve and extrapolating the capillary pressure curve.

  • Patent number: 10655461
    Abstract: A method, apparatus, and program product for determining a formation pressure for a reservoir. Measurement data for a pretest of a formation of the reservoir is received. The measurement data is analyzed to determine a last-read event and a corresponding last-read pressure. Derivative data for flow regime identification is determined based at least in part on the measurement data. The derivative data is analyzed to determine a pressure derivative response, and a formation pressure is determined based at least in part on the last-read event, the last-read pressure, and the pressure derivative response.

  • Patent number: 10371619
    Abstract: A method can include receiving porosimetry data for a range of pressures that spans a transition zone defined at least in part by a high-pressure end of a first pressure zone and a low-pressure end of a second pressure zone; detecting at least one artifact in the transition zone; computing accuracy information for the high-pressure end of the first pressure zone and the low-pressure end of the second pressure zone; computing a pressure-volume adjustment based at least in part on the accuracy information; and outputting a pressure-volume relationship in the transition zone based at least in part on the pressure-volume adjustment.

  • Patent number: 10219793
    Abstract: A delivery system for flowable substances includes a squeezable container having a sealed proximal end, a sealed distal end having a dispensing neck, and an outer wall that surrounds a storage reservoir. The delivery system has a container support frame assembled with the squeezable container having a proximal edge secured to the sealed proximal end of the squeezable container, a distal edge secured to the dispensing neck of the squeezable container, and first and second lateral edges extending between the proximal and distal edges and overlying opposing sides of the squeezable container. The proximal and distal edges and the first and second lateral edges define a central opening of the container support frame that provides access to the outer wall of the squeezable container. The container support frame has an elongated handle that extends proximally from the proximal edge of the container support frame.
