Pemex’s Temperature Bump Swells Oil Giant’s Production Figures

Petroleos Mexicanos is measuring crude production at a warmer temperature than government regulators, inadvertently inflating the oil giant’s output figures, according to people familiar with the practice.

Pemex gauges hydrocarbon production at 20 degrees Celsius (68 degrees Fahrenheit), rather than the National Hydrocarbons Commission’s 15.56 Celsius standard, said the people, who asked not to be identified because the information isn’t public.
