“A lot of rigs in TX do this. Thats one of the reasons their flareoff is so much less.”
What rigs are you talking about?
Drill rigs and Frac rigs are all powered by big tractor-trailer size diesel generators, usually more than one.
This means a constant stream of diesel tankers coming and going.
But many of these generators are being converted to also run on flare natural gas where it’s available, usually on sites with multiple pads.
