Patent ID: 8636070

Claim:
A method of generating high pressure dual phase mixture, the method comprising: mounting a dual phase mixture generator on a transportable platform, wherein the dual phase mixture generator comprises a mixing chamber connected with at least a first inlet, a second inlet, and a first outlet; mounting a first container and a first pump on the transportable platform, wherein the first pump is operably connected with the first container; deploying the transportable platform at a wellsite; introducing a base fluid into the first inlet under high pressure wherein the base fluid is a cement slurry containing a foaming additive and wherein the cement slurry containing the foaming additive is produced by cement generating equipment; introducing a gas into the second inlet under high pressure; combining the base fluid with the gas in the mixing chamber to generate a high pressure dual phase mixture; discharging the generated high pressure dual phase mixture via the outlet; introducing the high pressure dual phase mixture into a well at the wellsite; mounting a second container and a second pump on the transportable platform, wherein the second pump is operably connected with the second container; wherein the first container contains a foaming additive and the first pump pumps the foaming additive to the cement generating equipment for mixing with the cement slurry produced therein, and a mixture of the foaming additive and the cement slurry is introduced into the first inlet of the dual phase mixture generator; and, wherein the second container contains liquid nitrogen and the second pump pumps the liquid nitrogen from the second container into the second inlet of the dual phase mixture generator.
