Oilfield applications of liquid metering are covered in this module, and various liquid metering systems are described in detail. Maintenance concerns are also explained, with attention to the effects of gas, solids, turbulence, and normal wear on metering equipment
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.
