Course Overview

This primer on Oilfield Metering reviews the methods used to measure fluid volumes in the oilfield for accurate accounting, process monitoring, and custody transfer. Liquid metering techniques are discussed first, followed by gas metering. The first part of the course concerns methods of liquid metering. Positive displacement, turbine, vane, paddle, orifice, and vortex meters are described. Maintenance, wear, and the effects of gas and solids in the liquid stream are reviewed. The second part of the course concerns methods of gas measurement. The unit describes orifice metering equipment in detail, and emphasizes the importance of maintenance and inspection. Methods of recording accurate measurements are reviewed, and the equations for calculating gas volumes are explained. This Oilfield Metering Primer comprises three computer-based training modules, each representing two hours of instruction and exercises.

Module Overview

The first Gas Metering module covers the basic theory of gas measurement through an orifice. It describes metering equipment, measurement and recording devices, and gas flow calculations. The module explains how to read chart data and concludes with two gas flow simulations.
