Abstract
Described herein are systems and techniques for improving operation of equipment that identify compounds included in a slurry that exits a wellbore during a drilling operation. Mass flow rates, volumetric data, wellbore equipment data, and other information may be used to identify a total volumetric density of the slurry. Calculations and/or other evaluations may be performed to identify a volumetric density of materials other than a gas included in the slurry. The volumetric density of the other materials may be subtracted from the total volumetric density to identify a volumetric density of the gas included in the slurry. Estimates of percentages of hydrocarbons and molar mass equations may be used to estimate masses of combined sets of hydrocarbons included in the gas. When a volumetric density of a combined set of hydrocarbons matches the gas volumetric density, the gas may be classified as including the set of hydrocarbons.
