A method to cement a wellbore is provided wherein two fluids are transported into the wellbore through separate conduits, and combined within the volume to be cemented. The two fluids set to become a hardened cement after a short time period. The two fluids are preferably passed through a static mixer at the ends of the conduits within the wellbore to provide uniform contact between the two fluids. The two fluids are preferably a wellbore cement and an accelerator for that cement. Because the cement sets within a short time period, fluid loss from the wellbore is minimal. Additionally, the static head to which the formation is exposed is not excessive, even if a cement slurry having a density that exceeds the hydraulic fracture gradient of the formation is used.
A method for providing a set cement within a volume in a wellbore, the method comprising the steps of: providing two conduits, each conduit having an end terminating in a lower portion of the volume in the wellbore to be cemented; providing two fluids that, when combined, form a cement slurry that h
A method for providing a set cement within a volume in a wellbore, the method comprising the steps of: providing two conduits, each conduit having an end terminating in a lower portion of the volume in the wellbore to be cemented; providing two fluids that, when combined, form a cement slurry that hardens within a short time; passing the two fluids to the lower portion of the volume in the wellbore through the two conduits so that the two fluids combine in the volume in the wellbore creating a rising level of cement slurry in the volume in the wellbore; raising the ends of the two conduits within the volume in the wellbore at about the same rate as a level of the cement rises within the volume to be cemented; and allowing the cement slurry to harden within the volume in the wellbore.
