TECHNIQUES FOR NATURAL GAS SAMPLING A DISCUSSION OF FIELD METHODS FOR OBTAINING SPOT SAMPLES Natural gas sampling is performed for many reasons. Primarily sampling is performed to determine total gas composition, gas quality, and gas value. The three techniques normally used to obtain gas samples are continuous composite sampling, continuous online sampling, or spot sampling. This paper will discuss the various spot sampling techniques, proper sampling implementation, and equipment…

TECHNIQUES OF GAS COMPOSITE SAMPLING While inaccuracies in measurement can be costly and common, they are also avoidable in many cases. Technicians willing to study the experiences and best practices of industry leaders can make a world of difference by applying what they’ve learned and sharing this knowledge with others. Composite sampling is a straightforward method. When managed correctly, samplers…

SAMPLING CHALLENGES ASSOCIATED WITH UNCONVENTIONAL GAS SOURCES Advances in exploration, drilling and production technologies make it feasible to extract natural gas from sources that in the past have been regarded as unconventional and so, such sources are becoming a larger percentage of the gas supply. The feasibility of producing gas from a source is the primary factor in determining whether that source…

USE OF EQUATION OF STATE (EOS) SOFTWARE 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…

MEASURING HYDROCARBON AND WATER DEWPOINTS Hydrocarbon Dew Point (HDP) remains one of the key quality parameters of natural gas streams. Its determination is needed for operational and safety considerations, as well as to satisfy tariffs and regulations in US and overseas pipeline operations. The recent development of shale gas in US has added to the need for accurate and consistent…

PRINCIPALS OF ODORIZATION In the one hundred and thirty years, or so that we have known natural gas as a fuel source in the United States, the demand for natural gas has grown at an astounding rate. There is virtually no area of North America that doesn’t have natural gas provided as an energy source. The methods of…

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.…

DEW POINT WET GAS AND ITS EFFECT ON NATURAL GAS SAMPLING SYSTEMS Wet gas measurement is becoming widely used in the modern oil and gas market place. The effect of entrained liquid in gas and its impact on measurement systems is being researched world-wide by various laboratories and JIP working groups. The impact can be very significant financially. Hydrocarbon Dew Point can also effect the financial operation…

DEVICES FOR FIELD DETERMINATION OF H2O IN NATURAL GAS H2 O vapor is an undesirable component of natural gas. It takes up space in the pipeline and provides no fuel value. In higher concentrations it can condense into liquid water in the pipeline and cause corrosion, especially in the presence of carbon dioxide or H2 S. Liquid water can also cause damage to turbines.…
