  • Patent number: 11486248
    Abstract: Drilling fluid can be monitored throughout a drill site and at various stages of drilling operations. The drilling fluid may be analyzed to identify components that make the drilling fluid as well as the volume of each of the components, The volume of each component can be used, for example, to determine a percentage of water in a water-based drilling fluid and the average specific gravity of the water-based drilling fluid without further decomposition of the drilling fluid. The percentage of water and the average specific gravity can then be used to modify the drilling fluid, in real-time, based on conditions in the wellbore.

  • Patent number: 11300490
    Abstract: Systems and methods for adjusting well operations utilize measured values and curve fitting to determine predicted values of the gel strength of well-treatment fluids. The systems and methods are exemplified by first measuring a plurality of measured values representative of the gel strength of the well-treatment fluid, then determining a mathematical function that fits the plurality of measured values. From the mathematical function, the projected values are determined. The projected values are representative of the gel strength for the well-treatment fluid after a projected-value static period.

  • Publication number: 20210238938
    Abstract: Systems and methods of the disclosed embodiments include taking a first sample of a drilling fluid at a first time, measuring, with a rheometer, a first viscosity dial reading of the first sample, taking a second sample of a drilling fluid at a second time, measuring, with the rheometer, a second viscosity dial reading of the second sample, weighting the first dial reading and the second dial reading based on an elapsed time since the first time and an elapsed time since the second time, and calculating a shear stress vs. shear rate function of the drilling fluid for a plurality of temperatures and a plurality of pressures based on the weighted first viscosity dial reading and the weighted second viscosity dial reading.
