  • NOVEL WEIGHT MATERIALS FOR USE IN CEMENT, SPACER AND DRILLING FLUIDS
    Publication number: 20150299552
    Abstract: A drilling fluid, spacer fluid and cementing compositions for use in subterranean wells are disclosed along with methods for making using same, where the compositions include a weighting system having an effective amount of a metal silicon alloy, mixtures of metal silicon alloys, or mixtures of metal silicon alloys and conventional weighting agents, to produce compositions having a desired high density, while retaining other fluid properties such as pumpability, gas tight sealing, low tendency to segregate, and reduced high temperature cement strength retrogression.

  • Transitional sleeving for coaxial cable
    Patent number: 6013875
    Abstract: Transitional sleeving for use with coax cable being inserted into an opening to prevent bending or flexing of the cable too sharply, includes an elongated, hollow sleeve, having reverse bend segments with strengthening ribbing attached to one side of the reverse bend segments. The sleeving may be provided with a collar at the end adjacent the opening into which the coax cable is to be inserted to hold the sleeving in position in the opening.
