Introduction

Flow measurement and custody transfer systems play a critical role in the oil and gas industry, directly affecting revenue generation, hydrocarbon accounting, fiscal compliance, production allocation, and commercial transactions. As hydrocarbon production moves through the value chain, accurate and reliable measurement becomes essential for determining ownership, calculating entitlements, minimizing disputes, and ensuring regulatory compliance.

This advanced course provides participants with a comprehensive understanding of flow measurement technologies, custody transfer principles, metering system design, uncertainty analysis, calibration, verification, and performance optimization. The course focuses on industry best practices and international standards governing custody transfer measurements, enabling participants to improve measurement reliability, reduce uncertainty, and maximize operational and commercial performance.

Through practical examples, case studies, and technical workshops, participants will gain the knowledge and skills required to evaluate, operate, audit, and optimize flow measurement and custody transfer systems across upstream, midstream, and downstream facilities.
