Would someone explain the ESD (Electric Submersible Pumping) system? I'm just curious about it's implementation at Great Divide. My impression is they found during evaluation that this is something that would be useful, and it seems that this wasn't able to be determined before the well pairs were first set up. But I don't know, are these sometimes used right off the bat, or are they often put in later when decided to be useful? Maybe it's part of the learning curve.

On a side note, I was happy to see the latest press release, and the new presentation looks good. It looks like one of the talking points may be about the slowing approval process.
