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. …
Chromatography is one of the most widely used means of performing chemical analyses in the world. Russian botanist Mikhail Tswett is credited with discovering the technique of chromatography. Using alcohol as a mobile phase and chalk as a stationary phase, Tswett was able to separate various plant extracts.
Differential Pressure (DP) Flow meters are popular for being relatively simple, reliable and inexpensive. Their principles of operation are relatively easily understood. However, traditionally there has been a misconception that no DP meter self-diagnostic capabilities exist and as such only upgrading to newer ultrasonic or Coriolis technology can help bridge this gap. In 2008 & …
The Natural Gas and Oil industry is continually driven by cost cutting measures and the need to gain more operational efficiencies and visibility to regulatory requirements. This paper summarizes a solution in which wireless instruments integrate with other conventional equipment to offer a rapidly deployable advanced well optimization system.
Electromagnetic flow meters possess the ability to deliver real time diagnostic data regarding meter health and flow processes. Using the onboard diagnostics can help an individual trend fluid quality and measurement accuracy by understanding each KPI and how it correlates to a known standard.
Within the upstream sector of the oil and gas industry, the custody transfer of natural gas is usually determined by orifice measurement which is governed by a sales agreement between the producer and pipeline company.
An ultrasonic meter falls into the classification of inferential meters. Unlike positive displacement meters that capture volume to totalize volume, inferential meters measure flowing gas velocity to totalize volume. Ultrasonic meters use sound waves to measure flowing gas velocity to infer volume.
This paper discusses fundamental principles of ultrasonic gas flow meters used for measurement of natural gas and the available basic diagnostic capability to assess meter operation and performance.
Measurement, control, and automation are critical to today’s business environment. However, the electronics that enable these systems to function, and make these systems so valuable, can be vulnerable to the damaging effects of overvoltage transients.
Can the effectiveness of skills training be measured? A Region Director friend of mine who works for a large natural gas pipeline company complained that his new measurement employees (new hires and experienced personnel that have transferred into gas measurement) are not performing required tasks and activities to his expectations.
