1.1 This test method covers the determination of light hydrocarbons, their boiling point distribution and cut point intervals via gas chromatography in live crude oils and condensates with VPCR4 up to 200 kPa at 37.8C. 1.2 Methane (nC1) to hexane (nC6) and benzene are speciated and quantitated. Samples containing up to 0.5 mass% methane, 2.5 mass% ethane, 10 mass% propane and or 20 mass% butane are analyzed. A 0.01 mass% lower limit exists for these compounds. 1.3 This test method may be used for the determination of boiling point distribution of live crude oils and condensates from initial boiling point (IBP) to 391C (nC24). The nC24 plus fraction is reported.
method is sponsored by Canadian Crude Quality Technical Association to determine light hydrocarbons in live crude oils and condensates to address issues of safety in transport and commerce. Tight oil from fracking operations such as Bakken crude and condensates.
