Abstract

The paper present the result of field experiments and analytical studies that bring forth potential solutions to the problem of behind-the-casing leaks encountered during well completion operations. Requirements to strength capacity and stress/strain behavior of cement sheath are highlighted. These properties should be taken into account while formulating oil well cement compositions intended for wells selected for further perforation and hydraulic fracturing operations.

Key words:

cement sheath, strength, stress-strain behavior, stresses
