Study compares C6+ characterization methods for natural gas phase envelopes

A recent study applied different C6+ characterization techniques to generate a phase envelope for natural gases and, using these techniques and a single dewpoint measurement, generated a relatively correct phase envelope.Using the single dewpoint measurement, we determined the appropriate component or cut distribution for C6+ and evaluated the accuracy of each method for two case studies covering rich and lean natural gases.We evaluated the effect of four C6+ characterization techniques for generating phase envelopes for natural gases. With these techniques, a single dewpoint measurement was used to generate a relatively correct phase envelope.Using the single dewpoint measurement, we det...
