Integrated Approach to Well Integrity Data Quality Management Initiative in Shell Nigeria

Abstract

Recent regulations and standards demand that there is a need for a systematic Well Integrity Management and control during the entire life cycle of a well. Availability of reliable Well Integrity data is fundamental to a proactive, efficient and transparent life cycle Well Integrity management. The use of low cost smart systems, processes, and incorporation of a number of API performance standards have been adopted and implemented by operators to ensure that their Assets are operated within their defined operating envelopes and meet the required performance standards and process safety requirements. The operate phase is the longest phase in the Well Integrity life cycle management and thus a critical phase that requires intelligent systems, experience and resources to maximize and optimize the life cycle value of the Asset. This phase can span decades and usually involves data acquisition, assurance and analysis For well integrity prediction. The key challenge for operators is the ability to maintain a comprehensive and reliable dataset for proactive Well Integrity management due to reasons ranging from resources to gaps in critical data as a result human error and legacy well issues. This paper will discuss the Well Integrity data quality gaps, key challenges, data management architecture framework, improvement initiatives, lessons learnt and the impact in the overall Well Integrity Compliance.
