EVP, Exploration & Production at EOG Resources
Yes, good morning, Arun. This is Jeff Leitzell. So as Billy stated, our ability to counter these inflationary pressures and some of the supply chain constraints that you talked about. It's really just a huge credit to our team's operational execution, their innovative culture and really continuing to improve on the efficiencies. So just to give you a little bit of color and some examples, start off with our drilling operations, our teams continue to increase their efficiencies and that's primarily with EOG's in-house motor program and our proprietary bit cutter development, which we can design both of these uniquely around all the formations we drill in each of our plays. And our Eagle Ford operations, they're just a perfect example of this. We've increased the drilled footage per day by over 17% this year. And this is one of our more mature plays that we've been drilling in for 13 years. So really to EOG, no matter how far along we are in development, there's always improvements that can be made.
And then on the same topic there with the Eagle Ford, they've just done an outstanding job of reducing their drilling fluid costs also, even as diesel prices have risen and that's primary base in those fluids. We've done this by optimizing the density and the additives and the drilling fluid in each area, really to try to reduce those fluid losses, which has resulted in a per barrel savings of about 20% so far in 2022.
And then just a couple more basic examples in completions, our field team, they continue to see really good improvements there and they've increased their overall completed lateral per foot per day by 10% compared to 2021 for the total company. And as we've talked about in the past, one of the main drivers in this is really our continued implementation of super zipper operations. So we've talked about last year, where about a third of our activity was super zipper. And this year, we had a goal of trying to get to 60%, and we're just about there right now.
So this is really significant because pretty much every additional well that we super zipper, we realize the savings of up to $300,000 per well or that equates to about 5% of the total well cost. So another new process on the innovation side that we've been implementing and testing is something called continuous frac pumping operations. So just a little bit of a rundown, typically in any completion operations, you have some unplanned maintenance. And in order to be proactive, our field teams have started planning some of that scheduled maintenance periods of about three to four hours every three days. And what this has helped us do is really minimize any of that unplanned maintenance and really greatly increase our overall efficiencies. So in the past quarter, really primarily in the Eagle Ford, we've started some testing in the Delaware basin, but we've been able to increase our completed lateral per foot per day by roughly 30%. So that's really just a huge time in cost savings there. And what we plan on doing is we optimize this process. We'll continue to roll it out to all of our operating areas.
And then lastly more on the supply chain and material side of things, I just wanted to touch on a couple of our savings from the water and the sand cost side of things. In the Delaware basin, our team continues to reduce their water costs by optimizing the reuse process, which right now is approximately 90% of all their sourced water. And they're really doing this just through increasing the automation of all of our infrastructure and reducing the overall treatment cost per barrel, which we realized about a 9% reduction in each barrel of reuse water for 2022. And this is pretty significant, not just for capex, but also on the operating expense because every barrel we're allowed to reuse, is one less that we have to dispose of.
And then finally here, over on the sand logistics side, EOG, we've been in the sand business in self sourcing for about 15 years now. And we continue to reduce those costs across the company. For example, out in the Delaware basin, we continue to advance our abilities to get that sand closer to the wellhead and ultimately reduce the amount of trucking needed. And plans are, we're going to open up a second plant in the second half of next year. And we really anticipate to see some pretty good savings from Q1 through the rest of the year of about 20% per pound. So these are just a few of the many examples of how our operations teams just performing and really giving us great confidence that we'll be able to counter a lot of these inflationary pressures and supply chain constraints through 2022. And as Billy will talk about here 2023.
