This paper was prepared for presentation at the SPE Technical Symposium of Saudi Arabia Section held in Dhahran, Saudi Arabia,  7-9 June 2003.

Abstract:

This study evaluates the most frequently used mathematical models to determine reservoir-fluid properties from field data for the Middle East and Canadian crude oil samples. The best three mathematical models for each PVT properties were selected using a large database of reservoir-fluid studies of samples representing Middle East and Canadian crude oils. The comparison is based on the average absolute relative percent errors. This paper gives the best mathematical models for field applications for estimating bubblepoint pressure, solution gas/oil ratio, oil formation volume factor at bubblepoint, undersaturated oil compressibility and undersaturated, saturated and dead oil viscosities.
