I believe the company was heavily involved in trying to get the oil out of old reserves. Think they purchased quite a few of them.
If memory serves, most oil reserves are "capped" while the majority of the oil is still in the ground. The pressure drops after a certain amount of the oil is taken out. Then you have to pump it out — which can be more expensive then just starting a new rig.
Fracking has come along and changed all that. Hopefully NNYR is still in business and making a lot of money.
