• Abstract:

  The demand for lightweight cement in areas of low-strength formation has led to the increased use of foamed cement in PanCanadian’s wells. Foamed cementing involves mixing surfactant upstream of the cement pumper and injecting nitrogen into the mixing surfactant upstream of the cement pumper and injecting nitrogen into the pumper discharge line, with a foam generator installed downstream. The “constant foam density method” was used. Recent field tests by PanCanadian confirmed that foamed cementing is only slightly more expensive than conventional cement jobs but less costly and involving less mechanical risk than multi-stage jobs. At the same time, it can be considerably less expensive than glass or ceramic microspheres cementing.
