  • Patent number: 11970308
    Abstract: A container (10) and a method facilitating measuring a member, for example measuring the length or perimeter of a user's lower leg e.g. the calf and/or ankle. The method comprises aligning and locating a first datum (24) of the container (10) against a second datum on the member followed by rolling the container's perimeter relative to a section of the member to be measured. Measurement is complete when the container (10) has rolled from the first datum (24) along the minor surfaces until a point of the container (10) reaches an extremity of the member/dimension being measured; the extremity may be the second datum, where a circumference of a member is being measured. When rolling the perimeter of the container (10) is complete a point of the container face (12) will be aligned with a point representing the extremity of the dimension being measured or the second datum. Alignment of two points at the extremity of the measured member is indicative of the dimension of the member.

  • Patent number: 11851988
    Abstract: A well unloading valve for a petrochemical well tubing comprising a flow passage connecting an annulus outside the tubing with the inside of the tubing; a lock-out sleeve for selectively closing the flow passage, wherein the lock-out sleeve can be moved from an open to a closed position by means of hydraulic pressure within the tubing; an electrically activated motor module for moving a seal, wherein the seal selectively opens a hydraulic connection from the inside of tubing to the lock-out sleeve for moving the lock-out sleeve hydraulically from the open to the closed position; and a check valve within the flow passage for allowing a flow from the annulus into the tubing and for blocking a flow from the tubing into the annulus. Further a method for unloading a petrochemical well tubing is claimed.

  • Patent number: 11579329
    Abstract: Estimating wear on bottom hole assembly (BHA) components utilizes a rock hardness index using analysis of drill cutting. Estimating the amount of wear on borehole assembly components comprises measuring the rock properties in drilled cuttings from a borehole. A hardness value is assigned to each mineral present in the drilled cuttings. A hardness index is calculated for a drilled borehole interval. A wear resistance factor is assigned to each BHA component of the BHA. The wear resistance factor depends on the wear resistance of each BHA component. A wear value for each BHA component is calculated based on the hardness index for the drilled borehole interval, the wear resistance of the BHA component, and drilling parameters.

  • Patent number: 11193341
    Abstract: Disclosed are systems and methods for monitoring drilling fluids in real time. One method includes circulating a drilling fluid into and out of a borehole, generating a first output signal with a first optical computing device arranged near an outlet of the borehole, the first optical computing device having a first integrated computational element configured to optically interact with the drilling fluid, receiving the first output signal with a signal processor communicably coupled to the first optical computing device, determining the concentration of a gas present in the drilling fluid at the outlet of the borehole with the signal processor and generating a resulting output signal, conveying the resulting output signal to one or more peripheral devices, and adjusting one or more drilling or completion parameters in response to the concentration of the gas present in the drilling fluid.
