I think as we continue to push the horizontal legs out further, so you can access more reservoir from the same surface location, that's really the innovation. It's a combination of being able to drill out further, but it's also the innovation on the completion side of the technology, to be able to place the sand and fracturing fluids out further as well.
As well, I think going to the greener fluids will be quite innovative. I guess the final bit would be less reliance on surface water, by recycling non-freshwater sources.
