  • Patent number: 11174723
    Abstract: A method for determining along-hole well depth of a wellbore. A value for a calibrated drill string length is calculated, by determining length of drill pipe sections which form a drill string, prior to insertion of the drill pipe sections in the wellbore as part of the drill string. A correction which is calculated based upon one or more physical characteristics of the drill string. At least one of the physical characteristics is derived from measurements made at defined locations in the wellbore when the drill string is under tension whilst being pulled out of the wellbore. The correction to the calibrated drill string length is applied to obtain a value for a corrected drill string length as a measure of along hole depth. Advantageously, by calculating the correction based upon physical characteristics of the drill string associated with the process of pulling the drill string out of the well, the present invention reduces the number of physical characteristics which affect the correction.

  • Patent number: 10975693
    Abstract: Disclosed are methods and apparatus pertaining to processing in-situ, real-time data associated with fluid obtained by a downhole sampling tool. The processing includes generating a population of values for ?, where each value of ? is an estimated value of a fluid property for native formation fluid within the obtained fluid. The obtained data is iteratively fit to a predetermined model in linear space. The model relates the fluid property to pumpout volume or time. Each iterative fitting utilizes a different one of the values for ?. A value ?* is identified as the one of the values ? that minimizes model fit error in linear space based on the iterative fitting. Selected values ? that are near ?* are then assessed to determine which one has a minimum integral error of nonlinearity in logarithmic space.

  • Patent number: 10974791
    Abstract: A technique for calculating the motion and stress at any location along a riser or mooring line that is connected to an oil platform using data from multiple motion sensors that are installed above the water level on the platform is disclosed. A relationship between motion at the locations of the motion sensors and motion at the point at which the riser or mooring line is attached to the platform is determined from a model of the platform. From this relationship, the motion at the location at which the riser or mooring line is attached to the platform is computed from motion that is measured by the motion sensors. The motion and stress at any location along the riser or the mooring line is calculated based on the acceleration at the location at which the riser or mooring line is attached to the platform.

    Abstract: Systems and methods for initiating an emergency disconnect sequence (EDS) are provided. In an aspect, a disconnection system is provided and configured to initiate the EDS, and includes a controller including a processor and a memory operably coupled to the processor. The controller receives, from a set of motion reference units (MRU(s)) operably coupled to a flexible joint, position data generated by the set of motion references units and associated with the joint when the joint is operably coupled to and disposed between a drilling riser and a lower marine riser package (LMRP). The controller determines, based on the position data, an angular offset of the joint. The controller sends, to a subsea control pod disposed at or adjacent to the LMRP, a trigger signal in response to determining that the angular offset exceeds a predetermined threshold, such that the subsea control pod initiates the EDS.

  • Patent number: 10803534
    Abstract: Method for mapping a 3D grid or mesh from a faulted subsurface domain to a continuous design domain, wherein the grid may be used to represent a discrete model of a subsurface material property (such as permeability) to use, for example, in a reservoir simulator. The mapping is geometry-based, not physics-based. The mapping is determined by an iterative optimization procedure designed to penalize deformation of tessellated mesh cells (703) in the design domain compared to their geometric quality in the faulted domain (701), but subject to stitching constraints (702) appearing as a penalty term or Lagrange multiplier term in the optimization objective function to influence the final mesh to co-locate pairs of points identified on opposite sides of a fault as having been located together before the fault occurred.
