Wellheads Liquids Measurement Liquids measurement in the oil patch is suddenly getting a lot of attention. Some are dismayed at the low level of technology used to measure liquids. Today, custody transfer of 80 to 85% of onshore crude and condensate production is still documented by a hauler climbing to the top of the tank and strapping it.…

Fundamentals of Mass Measurement – Coriolis Meters The first flow meter utilizing the Coriolis force to measure mass flow was patented in 1978. Today, hundreds of thousands of Coriolis meters are in service in the hydrocarbon industry to measure mass, volume, and density of a wide variety of fluids. The American Petroleum Institute published Chapter 5.6 entitled “Measurement of Liquid Hydrocarbons by…

Fundamentals of Natural Gas Liquid Measurement The measurement of natural gas liquids (NGL) is similar in many respects to that of other hydrocarbon liquids but is markedly different in other aspects. The main difference in NGL measurement is the need to properly address the effects of solution mixing. Measuring NGL by mass measurement techniques will properly address solution mixing effects because…

Fundamentals of NGL Sampling Systems The purpose of this paper is to discuss in depth the systems we use as a standard to sample natural gas liquids, or NGL’s. Before we discuss the systems and methods used to sample these products, we must first clearly define what NGL’s are. NGL’s can be a combination of any fluid in liquid form…
