Basic Oilfield Mathematics covers general mathematical calculations that are likely to be encountered in the oilfield. The course takes a practical approach, featuring numerous examples for tubular weights and volumes, tank capacities, API gravity, downhole static pressure, and unit conversion from one unit to another. It covers basic physics concepts such as density and specific gravity. The effect of well deviation on measurement and pressure calculations is explained. Principles of pressure and force are illustrated with examples. A few more advanced topics include fluid measurement and orifice metering calculations, and a few exercises in oilfield economics. This course comprises two training modules.
