Section 1

This module includes an overview of the numerous well types, as well as applicable rules and laws and their history, as well as a series of past incidents related to well integrity failure. The need of well integrity control is further demonstrated by well failure data. The types of wells discussed include:

• Wells that produce oil
• Wells that produce oil and natural gas
• Wells that only produce natural gas
• Shut-in, Suspended, Abandoned
• Onshore & Offshore
• WAG, Water injector, Gas injector
• Appraisal wells, Development wells

Section 2

This module introduces the various well components as well as the related well integrity concepts and requirements. It describes the concept of well barrier schematics, as well as the major and secondary barriers of a well, as well as the design and selection criteria for each, as well as the initial test and verification needs.

• SSSV
• Completion String and Casing
• Production Packer
• Wellhead and Xmas Tree
• Tubing and Casing Hangers
• Cement Sheet

Section 3

A detailed explanation of the well lifespan, from conception through abandonment, as well as the needs and applicable concepts for each stage. The following are the stages (phases) of the lifespan that will be discussed:

• Basis of Design
• Design
• Construction
• Operation
• Intervention
• Abandonment

Section 4

Presents the important components of a successful Well Integrity Management procedure, as well as effective implementation strategies for each stage of a well's lifecycle. The following are some of the well integrity management elements discussed:

• Organization and Responsibilities
• Well Design
• Operational Procedures
• Data System
• Analysis

Section 5

The diverse failure modes and mechanical deterioration mechanisms of well barrier elements are summarized in this module.

Section 6

A thorough examination of the many mechanisms of internal/external corrosion and flow assurance difficulties, as well as the wells that are vulnerable to them. Techniques for control and monitoring are also explored. The following are examples of threats:

• Erosion
• Paraffins, Wax and Asphaltene

• Corrosion Issues (CO2, H2S)
• Sulphide Stress Cracking

Section 7

The inspection and monitoring approaches that could be used to assure well integrity, as well as a description of their acceptance criteria based on best practices.

• Well monitoring of:

• Annulus Pressure

• Assigning Consequences of Failure (COFs)
• Risk Allocation and Integrity Status

• Inspection Planning & Preventive Maintenance
• Management of change (MOC)
• Veracity wells

Section 9

This module covers the methodology and process of well anomaly management, as well as the detection, management, and maintenance of Sustained Casing Pressure.

• Anomaly criteria
