Based on volumes of production, the industry that calls itself “the oil and gas business” should properly be called the “saltwater business.” In some conventional and most shale plays, there are six or eight barrels (bbl) of water brought to the surface for every barrel equivalent of hydrocarbons.
What to do with it?
The volumes of oil and gas being produced in North America are rapidly rearranging global energy economics and even geopolitics. But at the same time a crisis may be coming to a head as producers wonder how and where to get lakes of water needed to frack wells—and even more to the point—what they are going to do with the oceans of saltwater produced?
The issue is creating a third business for midstream operators—crude oil, natural gas and now water.
Not an afterthought
For ages, water supply and disposal has been an afterthought, handled by producers themselves, truckers, disposal-well operators, oilfield-services firms, and water-treatment suppliers. That haphazard approach is today far from sufficient and integrated water-management has emerged as a major growth area. Midstream operators in particular are taking the matter with the gravity it deserves.
On the supply side, one midstream operator told Midstream Business, “If you don’t have water, you are not in the energy business.” On the disposal side, another confided, “If it is not handled properly, water could end up being the Achilles’ heel of booming U.S. hydrocarbon production.”
Two main factors—availability and cost–have been major drivers in the emergence of water management from an afterthought in oilfield services to a significant segment in the midstream, according to Josh Adler, founder of Sourcewater. “Just in the past few years, fracks have gone from 100,000 bbl (Mbbl) of water to 600 Mbbl or even 800 Mbbl. That is multiplied by the fact that operators plan multiple fracks in series on the same pad,” he told Midstream Business.
Until recently, 100 Mbbl of water in a pit could suffice. Today the need might be more like 3 MMbbl of water—almost all at once.
“Needing 30 to 40 times more water upfront is not just a difference in volume,” Adler explained, “it is a fundamental difference in kind. Until recently, operators could usually get all their water from a single surface-use agreement. But most surface owners just can’t supply that much water in that much time, so operators now have to search the whole area for supplies.”
In most cases that means sending landmen around to knock on doors.
“But when completion engineers say they have planned their water needs 12-18 months in advance, what they usually mean is that they have signed call options and rights-of-way with nearby ranchers and farmers,” Adler said. “Very rarely do they secure a guaranteed supply contract—they just assume the water will be there when they need it because everyone shook hands on a price and they know whom to call. But in a world of $60 oil, it makes economic sense for everyone to drill everywhere in the Permian, so now you suddenly have many different operators all calling on the same surface owners for the same water from the same aquifers at the same time—and needing six to eight times more water per well than before. No one has planned for that simultaneous demand. There are going to be a lot of water supply shocks this year.”
A third of completion
“There has been a complete transformation in the scale of water,” Jim Summers, CEO of H2O Midstream, told Midstream Business. “Today water can account for 20% -30% of the cost of drilling and completing a well, and as much as 50% of the operating cost. That is driving the evolution of the midstream business around water. The model is looking a lot like gas midstream.”
H2O Midstream began commercial operations in July 2017 when it acquired a produced water gathering system from EnCana and spent the subsequent six months converting that proprietary system to a fully integrated commercial one. H2O Midstream has recently added a second and third producer to that system, and is adding capacity for both transportation and disposal.
A new sector
Once that becomes more accepted, however, Summers sees water as a major sector in the midstream.
“We see this business through the lens of a midstream operator,” Summers said. “We see opportunity for the big midstream names to grow their portfolios through water. There will also be room for new standalone water midstream companies.”
DistributionNOW (DNOW) claims primacy in the segment of pumps as well as fabricated water transfer and disposal skids for injection wells. As such, the company is on the front lines of the evolution of water management in the midstream.
“This is a market we are watching very closely,” Brian Verdehem, director of engineering for process solutions, told Midstream Business. “The biggest concern for the folks we talk to is what are they going to do with all the produced water in shale wells. Operators have said that 7 bbl-10 bbl of produced water are separated for every one of oil.”
The disposal challenge
Cost has indeed grown, in some plays by an order of magnitude.
“Water used to be about 2% of the cost of a Permian well,” Sourcewater’s Adler said. “Now it can be as much as 20%. In the northern Delaware Basin water costs $1/bbl-$3/bbl without transportation. That means water can cost over $1 million per well. And it’s not an optional cost. If you don’t have all of the water you need, you are not in the energy business.”
Water costs, availability, and infrastructure vary greatly from basin to basin, and even within basins.
“The Delaware and Midland basins are very different,” Adler said. “In the Delaware there is lots of water, especially brackish and produced. It’s a wet play, but there is very little water infrastructure. The Midland basin is more built out, but has less water and a lot more operators drawing on it.”
Sourcewater is an online marketplace where producers and midstream operators can find and acquire water for fracking and place flowback and produced water for disposal or reuse.
“We started in the Marcellus as a way for producers to recycle produced water among themselves. There is a lot of inter-operator recycling in the Marcellus, but it is still rare in the Permian. That is not because of greater distances or lack of infrastructure, but mostly less economic motivation and fear of commercial and environmental liability. Produced water is classified as a waste stream, so there are statutory requirements for liability in the chain of custody,” Adler continued. “The cost and scarcity of water sources and saltwater disposal is not yet high enough in the Permian to overcome those hesitations—unlike in the Marcellus where there is virtually no saltwater disposal so recycling is a necessity.”
Produced water disposal may be an even bigger long-term challenge than water supply. The large volumes of water needed for fracking are dwarfed by the volumes of produced water that flow over the life of all the producing wells in a field. Adler believes produced water recycling between operators is the future of oilfield water supply.
“Produced water is plentiful exactly where you need it, which is where the oil is. There is no technical reason to use freshwater for any frack,” he said. “And if you go to one of the [Hart Energy] DUG conferences you will hear evidence that produced water actually works better for fracking. Reuse gets better results, it costs less, it’s better for the environment and our communities, and there is plenty available.”
That said, “the bigger midstream companies are not playing on the supply side of water because of the lack of long-term guaranteed supply contracts,” Adler explained. “This is currently a spot market business so more of a segment for smaller, local or regional operators.”
“The water business is growing much more rapidly than any other part of the midstream,” David N. Capobianco, CEO and managing partner at Five Point Capital Partners, told Midstream Business. Five Point has midstream water operations in the northern and southern DelawareBasin, as well as in the Eagle Ford and in the Arkoma. WaterBridge is its pure-play water midstream operation, but several other of its midstream portfolio companies have oil, gas, and water operations.
“Three pipes in a ditch is the way all midstream development will be done from now on,” Capobianco said, “but there still remains a meaningful transition from spot market water handling to permanent water management infrastructure. For the past few years producers have been like race cars speeding around a race track toward a wall at the end of the track. They have known the wall was there, but had no strategy relative to what they were going to do when they got there. … but now it is in sight. The wall is the mass-water management challenge they face as they ramp up production. We have crossed the tipping point, or the moment when the need for a permanent solution is no longer a luxury but a necessity.”
In many ways the development of the water segment of the midstream is following the path of the hydrocarbon midstream. “Originally, producers built out there own infrastructure, and later divested,” Capobianco noted. “Over time, I would expect that the lion’s share of water management infrastructure will be owned by independent third-party companies.”
Capobianco reckons that within a few years “almost all midstream operators will have water operations of some kind. It will be impossible to avoid if you are a midstream business.” The form the water midstream will ultimately take remains unclear. “It could end up like a utility, with large companies managing an array of local operations,” Capobianco said. “There is not really an existing model. Unlike oil and gas, the water molecules are not going to move very far.”
Water disposal has emerged as a major issue in Oklahoma due to the region’s unique geology. Water injected into suitable, porous formations has lubricated inactive faults, trigging sometimes significant earthquakes in a part of the country where seismic activity has been rare.
Water injection, understandably, has become a significant political and economic issue for the Sooner State. The quakes have been centered in central and north-central portions of the state.
And while injection is down in Oklahoma, seismicity is little changed.
“For all of 2017 the state of Oklahoma had 304 magnitude 3 earthquakes, which is more than California did,” Jake Walter, state seismologist with the Oklahoma Geological Survey, told Midstream Business. “That is even though Arbuckle Formation injection is now down to levels not seen since the middle of 2012, and at that time there were just a few magnitude 3 earthquakes.”
Current Arbuckle injection has dropped from a peak of 90 million barrels (MMbbl) per month in late 2014 to 40 MMbbl/month in early 2018.
The reduction of injection volumes has been driven by both regulation and economic forces on the oil and gas industry. The survey, based in Norman, Okla., has been working closely with the regulatory Oklahoma Corporation Commission on the issue.
“Mississippi Lime wells sometimes produce 80%- 90% water,” Walter said. “We hear that those kinds of wells are only economical at high prices for oil and low prices for water disposal. Now what happens if oil prices rise? We don’t know.”
