The Bureau of Land Management has initiated an environmental review of the right-of-way Enefit needs for its proposed utility corridor, which would connect its mine and processing plant to the Bonanza Power Plant outside Vernal. The corridor would also carry a 16-inch pipeline to Chevron’s east-to-west line that runs 11.5 miles north of the mine, as well as an 8-inch natural gas line, a 30-inch water line and a second 138-kilovolt power line. The pipelines would run underground.

Don’t need water or power but we need a 30-inch water pipe, a natural gas pipeline and a mainline to the nearest power plant.

Just a quick reminder … if your barrels require more and more energy to produce, you will need more and more barrels to maintain the same level of net energy.

But what about EROEI, that is, net energy of tight gas?
