  • Patent number: 11987743
    Abstract: The effectiveness of expansive cement systems may be diluted when, during a well cementing operation, commingling takes place between the cement slurry and a spacer fluid, a drilling fluid, or both. Incorporating expansive agents in the spacer fluid or drilling fluid may reduce or negate the loss of expansion at the cement slurry/spacer interface or the cement slurry/drilling fluid interface, thereby promoting zonal isolation throughout the cemented interval.

  • Patent number: 11988054
    Abstract: A technique facilitates pressure application downhole by locking a ball in place to prevent it from unseating even if the pressure is bled off. A ball seat is constructed with a locking feature for effectively capturing and retaining the ball once the ball is seated in the ball seat under sufficient pressure. According to an embodiment, the ball seat may be mounted at a desired position along an internal flow passage of a well string component. The ball seat comprises a throat section which is formed of a ductile material arranged in a suitable structure to enable a desired deformation upon receiving the ball under sufficient pressure. As the ball is pressed into the throat section, the material of the throat section deforms and partially springs back to resist movement of the ball in the uphole direction, thus capturing the ball in both the uphole direction and the downhole direction.
