| titleOfInvention | METHODS TO GENERATE GAS AND FORM FOAM IN COMPOSITIONS OF CEMENT FOR WELL. |
| abstract | The present invention provides improved methods for generating gas and foam in a cement composition introduced into an underground area penetrated by a perforation. The methods basically comprise the steps of providing and pumping a well cement composition containing an oxidizing agent into the underground area, through the drilling using one or more cement pumps. At the same time, provide and pump an aqueous solution or dispersion containing a gas generating chemical and a mixture of surfactants in the cement composition for running well under the pumps so that gas is generated and foam is formed in the compositions of cement. |
