A method for improving liquid injection into a rock formation. The method includes the steps of introducing a gas impulse device into a wellbore in the formation and pumping a pressurized liquid into the wellbore. The method also includes firing the gas impulse device periodically so that the device generates impulses of high pressure compressed gas. The gas expands through the pumped pressurized liquid substantially instantaneously increasing the liquid flow rate into the rock formation, and creates rapid cyclical injected liquid surges into the rock formation with liquid oscillation occurring inside the fractures and/or pores of the formation. The method may be used in regular oil production applications, waterflooding of wells that have ceased to be productive, in preventing lost circulation in oil wells, and in injecting hazardous wastes into rock formations. |

A method for fracturing an oil or gas formation. The method includes introducing a gas impulse device into a wellbore followed by pumping a pressurized liquid into a wellbore at a pressure equal to or lower than the estimated fracture pressure of the formation. Finally, the method includes firing the gas impulse device periodically so that the device releases high pressure compressed gas impulses. The impulses when expanding through the pumped pressurized liquid substantially instantaneously increases the fracturing liquid flow rate into the oil or gas formation. It causes the total pressure to exceed the actual fracturing pressure of the formation thereby initiating or extending fractures in the formation stimulating the flow of the oil or gas therefrom into the wellbore. |
