  • Downhole high temperature rheology control
    Patent number: 11566172
    Abstract: A method of treating a well comprising introducing a well treatment fluid into the well, and a well treatment fluid, are provided. The well treatment fluid comprises an aqueous base fluid, sepiolite clay, and a polymer component selected from the group of an acryloylmorpholine polymer, a polyvinylpyrrolidone polymer, and mixtures thereof. In one embodiment, for example, the method is a method of drilling a well. In this embodiment, the well treatment fluid is a drilling fluid.
    Type: Grant

  • Determining non-plastic state shrinkage in a cement slurry
    Patent number: 11156586
    Abstract: A system and method to determine a non-plastic state shrinkage (NPSS) characteristic of a cement slurry. The system and method can include operations of transmitting an ultrasonic signal through the slurry, recording a transit time of the ultrasonic signal as the slurry cures, plotting the transit time, measuring and plotting a shrinkage of the slurry, determining a transition of the transit time from an increased rate of change to a decreased rate of change, determining a first curing time at the transition, determining the detected volume at the first curing time based on the second plot; and determining a change in the detected volume from the first curing time to a second curing time, wherein the second curing time is after the first curing time.
