| titleOfInvention | Composition and method for cementing a well |
| abstract | The present invention is concerned with a composition for and method of performing primary cementing operations. The method comprises the use of a water slurry of a thixotropic cementing composition which rapidly develops sufficient static gel strength to reduce if not eliminate annular gas migration. The thixotropic cementing composition comprises hydraulic cement, water, an alkali metal aluminate and an alkali metal halide. |
