HM 25. Guidelines for the assessment of uncertainty in the oil and gas industry

Overview:

The estimation of uncertainty is a very important feature of measurement data analysis and management in the oil and gas industry. This document gives guidance on the procedures which can be used to provide an acceptable uncertainty estimate for each stage of the traceability chain leading to a final quantity measurement. The statistical principles are explained at a user level and the need for honesty and common sense is stressed throughout. The treatment and method are designed to comply with the internationally accepted Guide to the expression of uncertainty in measurement (GUM:1995). BIPM/ISO/OIML/IEC/IFCC/IUPAC/IUPAP.

This document supersedes HM 25 second edition, 1993 (IP PMM Part XIV Statistics for static and dynamic measurement) and incorporates and updates the EI (IP) technical report 370/99 (Revised May 2003) Assessment of measurement uncertainties in the oil and gas industry.
