CEMENTING PROCESS AND APPLICATION OF THIS METHOD TO REPAIR CEMENTINGS |
| abstract |
The subject of the invention is a method of cementing an oil well or the like comprising injecting a cement grout comprising a surfactant, and foaming said grout before allowing the cement to set, the grout used having a content of very low water (less than 50% by volume for ordinary cement-based systems and less than 72% by volume for micro-cement-based systems). |
