  • Patent number: 10983246
    Abstract: The systems and methods provided herein relate to extracting maturity-based properties from input log data obtained by a downhole well logging tool. A maturity inversion is performed using the input log data, a log response model, and at least one maturity model to extract maturity-based properties from the input log data. The maturity-based properties are provided in an output log, such that subsequent down hole operation of the formation may account for the maturity-based properties.
    Type: Grant

  • Patent number: 6770603
    Abstract: A wellbore fluid having a non-aqueous continuous liquid phase that exhibits an electrical conductivity increased by a factor in order of 104 to 107 compared to conventional invert emulsion comprises from about 0.2% to about 10% by volume of carbon black particles and one or more emulsifying surfactant(s) selected from the class including nonionic emulsifiers of Hydrophilic-Lipophilic Balance (HLB) less than about 12, and anionic surfactants wherein the counter-ion (cation) is any of alkali metal, ammonium, or hydrogen ions. This wellbore fluid can be used for drilling or completing a well and can be used for providing enhanced information from electrical logging tools, measurement while drilling, logging while drilling, geosteering and the like.

  • Patent number: 6612444
    Abstract: An apparatus for recovering a desired fraction of a raw material bearing the desired fraction has a vessel or cell defining a treatment chamber therein, with an inlet into the chamber for introducing a slurry of raw material to be treated into the chamber. An attrition zone is defined in a portion of the chamber proximate the inlet in the flow path of material introduced into the chamber, the particles being caused to impact against each other in the attrition zone to cause attritioning thereof. A floatation zone is defined in a distal portion of the chamber, in flow communication with the attrition zone, in which attritioned particles from the attrition zone can be contacted with gas bubbles to form a froth phase separated from the slurry by a slurry-froth interface such that the desired fraction is either selectively taken up into the froth phase by the gas bubbles or selectively left behind in the slurry. An outlet from the chamber for the froth phase is present.

  • Patent number: 5495104
    Abstract: A method is provided for detecting a junction between adjacent can ends which are arranged in a stack. The method enables a selected number of can ends in the stack to be counted. The method comprises the steps of illuminating the peripheral edge regions of can ends in the stack with a signal emitted by a emitter inclined at an oblique angle to a line normal to the central axis of the stack and detecting reflected signals from the ends of the peripheral edge regions of the can ends. Oblique illumination provides alternating regions of the stack reflecting a relatively high and relatively low light intensity. Detection of the light intensity across the length of the stack enables a junction between adjacent can ends to be determined.
