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.

Weight materials for use in cement, spacer and drilling fluids

A foamed cement composition is disclosed for utilization in performing a variety of well cementing operations, and to methods for making and using same. The foamed cement composition basically includes a cement, water sufficient to form a pumpable slurry, a gas sufficient to foam the slurry, a foaming agent and optionally a foam stabilizing agent.
