If your numbers are right and that fact that they only do approximately $2MM per quarter in revenue now, this one well grew their revenue by 12.5%? Does that seem right. If so, should find a few more of them.
Earthstone has an 8.4% interest in the well, so they receive 8.4% of the revenues. There is a decline rate, so the other person's estimates are probably high (unless the price of oil really jumps). But it is a strong onshore well.
