Abstract: In accordance with a method of this invention, formation integrity problems are discovered, diagnosed and corrected in successively drilled subterranean well bore intervals. If one or more of well bore fluid outflows, formation fluid inflows or inadequate well bore pressure containment integrity are discovered in a drilled well bore interval, well logs are run and other relevant well bore data is collected in the drilled well bore interval and analyzed to provide a specific treatment using a specific pumpable sealing composition for sealing and increasing the pressure containment integrity of the well bore. Thereafter, the sealing composition is pumped into the drilled well bore interval whereby the well bore interval is sealed or the pressure containment integrity is increased, or both.

Abstract: The present invention relates to improved well fluids that include hollow particles, and to methods of using such improved well fluids in subterranean cementing operations. The present invention provides methods of cementing, methods of reducing annular pressure, and well fluid compositions. While the compositions and methods of the present invention are useful in a variety of subterranean applications, they may be particularly useful in deepwater offshore cementing operations.

Abstract: In an embodiment, the shelf life of lightweight beads to be used in a cement composition may be extended by combining the lightweight beads with a fluid such as water to inhibit the lightweight beads from forming an agglomeration while they are being stored or transported. In another embodiment, lightweight beads that have already formed an agglomeration may be revitalized for use in a cement composition by adding a fluid such as water to the lightweight beads to reduce a size of the agglomeration. The agglomeration may originally have a width greater than or equal to about 1 inch. Adding the fluid to the lightweight beads may cause at least a portion of the beads to separate from the agglomeration into individual beads having a width of less than or equal to about 200 microns.
