From the report:
"...Pemex says that since 2006, it has had $300 million worth of natural gas condensate, a liquid hydrocarbon byproduct of natural gas production, stolen from its Burgos Field in northern Mexico. At times, Pemex says, thieves took in as much as 40% of the condensate production from the field, raiding 52 transfer and delivery systems spread through the area. They also hijacked condensate shipments at gunpoint."
Again, I'm flabbergasted that anyone would steal such low grade chemicals, particularly if force is needed.
