Quality Assurance (QA) and Quality Control (QC) in Oil and Drilling industry
Prepared and edited by: Dr. Amin Padash, President of the Iranian Scientific Association of Health, Safety and Environment Management and Engineering (HSEME)
Quality Assurance (QA) refers to the systematic process of ensuring that products or services meet specific requirements and standards through planned and organized activities. The main goal of QA is to prevent defects in the product or service by focusing on improving and refining the processes that produce them. It is a proactive approach that focuses on the prevention of issues, ensuring that everything is designed, implemented, and maintained to meet the desired quality standards.
In the context of industries like oil and drilling, QA includes all the procedures, audits, assessments, and training programs aimed at ensuring that operations are compliant with safety, environmental, and quality standards. QA also ensures that all the systems, equipment, and processes used during exploration, drilling, and production are capable of consistently meeting regulatory and operational requirements.
Main Differences Between Quality Assurance (QA) and Quality Control (QC)
While Quality Assurance and Quality Control are closely related, they are distinct concepts, and understanding the differences between them is crucial.
