Influences of Fracturing Fluid Injection on Mechanical Integrity of Cement Sheath under Four Failure Modes

Influences of Fracturing Fluid Injection on Mechanical Integrity of Cement Sheath under Four Failure Modes

The significant decreased wellbore temperature and increased casing pressure during fracturing fluid injection present a big challenge for the mechanical integrity of cement sheath in fracturing wells. Based on the theories of elastic mechanics, thermodynamics, and a multi-layer composed thick-wall...
