Jefrayn Energy Services has set the industry standard for how to manage well integrity throughout the wells life cycle; This standard it can be used to assess the application of many different well integrity management systems.
Well Integrity is the well’s capability to perform its function to contain and control the flow of fluids within predetermined barriers throughout its designed life. Managing well integrity begins with constructing wells that comply with integrity standards and preserving the well condition to the end of its life cycle. Software, tools and applications specified in many well integrity management systems fall quite short of the Jefrayn Energy Services definition of well integrity management system. Most of these systems apply to the operational phase of a well’s life whereas comprehensive well integrity begins at the exploration phase and continues through its abandonment.
The word integrity is derived from the word integer which means “a whole number” and or “the state of being integral, whole or unified” and it also refer to the soundness of construction. Between these two meanings one can safely define Well Integrity as” the unity of well objective, design and soundness of its construction”. Based on the above definition; Well Integrity is “the well’s capability to perform its function to contain and control the flow of fluids within the predetermined barriers throughout its designed life”.
Jefrayn Energy Services’ Well Integrity Management will ensure that wells are properly designed, executed, operated and maintained for a definite period of time after which they are safely plugged and abandoned. Well integrity can be realized through “application of technical, operational and organizational solutions to reduce risk of uncontrolled release of formation fluids throughout the life cycle of a well.” (Jefrayn Energy Services Standard WIMS-01). A comprehensive Well Integrity Management System should satisfy provide clear guidance from the planning to abandonment ensure the following:
