CALIBRATION STANDARD GASES In today’s natural gas industry, it is imperative that the standards used to calibrate are made to the utmost quality. Calibration standards are mixtures of known concentrations of components used to confirm or determine concentrations in samples. Calibration standards are needed for quality assurance/quality control, measurement and balance, quantitative sample analysis, and custody transfer. Preparation,…

EFFECTS OF WET GAS FLOW ON GAS ORIFICE PLATE METERS Orifice plate meters are one of the most widely used technologies in industry for gas flow metering. This is due to their relative simplicity, the extensive publicly available data sets that led to several orifice plate meter standards [1, 2, 3, 4] and the fact that they are a relatively inexpensive method of gas metering.…

TECHNIQUES FOR NATURAL GAS SPOT SAMPLING The need to be able to take a representative sample of a hydrocarbon product is necessary to ensure proper accounting for transactions and efficient product processing. Sampling can be accomplished by primarily three techniques; spot, continuous composite or continuous on-line sampling systems. The various spot sampling methods that are available and the implementation of these…

CONSIDERATIONS FOR SAMPLING WET, HIGH PRESSURE, AND SUPERCRITICAL NATURAL GAS This paper discusses the problems encountered when sampling wet, high pressure and supercritical natural gas for “on-line” BTU analysis, and provides solutions and comments on how they relate to the API and GPA industry standards for natural gas sampling. It also discusses the use of phase diagrams in the design and operation of a natural…

USE OF EQUATIONS OF STATE AND EQUATION OF STATE SOFTWARE PACKAGES Determination of fluid properties and phase conditions of hydrocarbon mixtures is critical for accurate hydrocarbon measurement, representative sampling, and overall pipeline operation. Fluid properties such as compressibility and density are critical for flow measurement and determination of the hydrocarbon due point is important to verify that heavier hydrocarbons will not condense out of a gas…

REQUIREMENTS OF AN EGM EDITOR The natural gas industry has adopted EGM as a means of increasing the speed and accuracy with which measurement information is obtained. This has created the need for an electronic data management system. These systems, if not properly designed and implemented, could potentially render the entire process useless. Therefore, it is essential that the system…

Upstream Natural Gas Sales Verification Producer and Pipeline Perspectives Within the upstream sector of the oil and gas indus- try, the custody transfer of natural gas is usually de- termined by orifice measurement which is governed by a sales agreement between the producer and pipeline company. In most cases, the gas sales agreement references a combination of American Gas Association (AGA), American Petroleum Insti-…
