| abstract | "PROCESSES TO IMPROVE THE DRAINAGE PROPERTIES OF ONE OR MORE DRY PARTICULATED CEMENT MATERIALS, TO STORE ONE OR MORE DRY PARTICULATED CEMENT MATERIALS IN A STORAGE TANK, TO CEMENT AN UNDERGROUND FORMATION BY A PERIOD OF DRILLING. OF OIL OR GAS WELL, CEMENT COMPOSITION, AND COMPOSITION TO CEMENT WELL ". Cement compositions and, processes for cementing into underground formations penetrated by well drilling where the flow properties of one or more dry particulate cement materials are improved and where the materials can be readily transported out of storage tanks and the like. A preferred composition of the present invention comprises a particulate flow-enhancing additive combined with one or more particulate cement materials, said flow-enhancing additive being composed of a solid particulate material which conducts a flow-inducing polar chemical, and a enough water to form a suspension that can be pumped. The processes basically include the steps of dryly combining the flow-enhancing particulate additive with one or more dry particulate cement materials; form a suspension that can be pumped using the one or more cement materials having the flow-enhancing particulate additive combined with them; pump the suspension into the well drilling; and then allow the suspension to solidify within the underground formation. |
