Quantify the risk of wellbore cement sheath failure

A lack of understanding of the stresses a cement sheath experiences and when or why the sheath may fail can lead to loss of zonal isolation, jeopardizing the future of the well. The lack of zonal isolation adversely affects all subsequent operations and degrades potential well performance and productivity.

CemSTRESS cement sheath stress analysis software is the key to understanding stresses in the cement sheath. It can model up to 10 strings simultaneously, analyzing the stress imposed on each string by a well event, such as pressure testing. CemSTRESS software analysis of radial and tangential stresses can determine cement sheath performance in compression, tension, or both, enabling the design of the set cement behind the casing to be optimized.

Use sensitization criteria to quantify risk

In addition, CemSTRESS software has the unique ability to "sensitize" many parameters, including formation flexibility support and standoff, so the decision about the best cement system to use can be based on the level of risk. Often, the best system is one with a low Young's modulus, such as a flexible cement system using FlexSTONE advanced flexible cement technology.
