  • Cementing casing strings in deep water offshore wells
    Patent number: 6273191
    Abstract: The present invention provides improved methods of cementing casing strings in deep water offshore formations penetrated by well bores. The methods are basically comprised of the steps of preparing a cement composition having a short transition time comprised of hydraulic cement, a water reducing additive, a dispersing additive, a compressive strength enhancing and set retarding additive, a set accelerating additive and water, placing the cement composition in the annulus between the casing string and the well bore and allowing the cement composition to set into a hard impermeable mass.
