As the oil and gas industry is moving toward to sustainable solutions (like produced water recycling for fracking) there are certain treatments that must take place prior to water reuse. Oil removal is one of them and has a sale value if treated and processed to meet the required BS&W (Basic Sediment & Water) for resale.
Plunging drilling costs have sparked an explosion of production out of the Permian, making the basin located in West Texas and New Mexico the most active and important oilfield in the world.
In fact, Texas is pumping so much oil that it will surpass OPEC members Iran and Iraq next year, HSBC predicted in a recent report. Reports from Exxon Mobil and Chevron confirm these numbers as well.
By 2024, Exxon has set a goal to produce over one million barrels per day from the Permian Basin. Chevron’s target is slightly below that at 900,000 barrels per day, effectively tripling their predicted 2019 output.
Since hydraulic fracturing first found its footing in the early 21st century, Permian oil production has increased around 500%.
This resulting explosion in oil production has completely remodeled the U.S. economy and acted as something of a nationwide stimulus package. However, with all the attention focused on the global oil paradigm shift, is there something even larger and more valuable rising to the surface?
Water Production is the big boom.
In that same time period, water use by the Permian energy industry will have grown by over 4,000%.
When producers blast a mix of water, sand, and chemicals to release oil and gas from rock formations miles underground, they not only unlock oil and gas, but also massive quantities of briny water long buried beneath the surface.
Drillers in the Permian Basin currently generate more than 1,000 Olympic-size swimming pools full of this murky, salty water every day. Handling it amounts to up to 25% of a well’s lease operating expense, according to analysts.
How is it possible that water use is growing almost 10x faster than oil production?
“The math on this is really, really easy,” said Christopher Manning, a managing partner of Trilantic Capital Management LP, which has invested in Solaris Water Midstream and committed as much as $100 million to the company.
“If the Permian goes up by one million barrels per day in oil production, it’s going up six million barrels in water. That’s an opportunity.”
There are additional water problems companies tend to overlook.
Naturally occurring produced water comes up simultaneously with the oil. But at a rate of 8 times as much. In addition, flow-back water, the water injected into a frac makes a return as well. All that water has to go somewhere.
Finding a long-term solution to the wastewater problem is essential for Permian producers.
A single shale well can produce more than a million of barrels of oil over its lifetime, and many times that amount of water.
Fledgling companies, many backed by private equity, are rushing to help shale drillers deal with one of their trickiest problems:
The real Permian boom isn’t a gusher. It’s a tsunami. The next big oil boom is actually water.
Finding, buying. selling, moving, storing, treating, recycling, and disposing of water (shale shaker screens).
And unlike the oil business, which has been going strong for almost 100 years in the Permian, the water business is less than ten years old. It’s a new, wide-open territory.
Industrial Fluid Management Facilitates Your Produced Water Needs
Industrial Fluid Management's focus is on treating and recycling of oil that accompanies the produced water.
It is our experience that we can see up to 10% oil by volume in every barrel of water produced (4.2 gallons of oil).
As the industry is moving toward produced water recycling for fracking there are certain treatments that must take place prior to water reuse. Oil removal is one of them and has a sale value if treated and processed to meet the required BS&W (Basic Sediment & Water) for resale.
Water Treatment and Its Works
Some water treatment and for reuse sites use a series of separator tanks to separate the oil, water, and solids. The water is further treated and sent through a series of filters then pumped to reservoir pits to wait for the next frac job.
The solids are hauled off for disposal and the oil is sent to tanks for gravity separation in the hopes of meeting the resale criteria. This gravity separation process can be extended for great lengths and not allowing the oil to separate properly which devalues the oil.
The Power of 3-Phase Centrifuges
Presently, Industrial Fluid Management is working with clients in improving the value of their oil by employing skid mounted three phase centrifuges (Tricanter Centrifuge) to collect the oil and separate the solids and water while getting the BS&W on the oil below 1% or less.
Our units are equipped with everything needed to start producing clean oil within a few hours of arriving on site.
The 3-Phase Centrifuge
The Industrial Fluid Management 3-Phase Centrifuge Package is designed:
- As fully self-contained Tricanter centrifuge package that includes provisions for processing all types of industrial and drilling slurries
- To contain all necessary equipment to handle all aspects of material separation to oil, water and solids discharges
- To include injection pumps and a static mixing manifold to add chemicals and/or additives to facilitate processing to the best possible outcomes
- To include a steam heater to heat the incoming product if required
The Centrifuge is capable of handling 440 GPM of water, and separating solids, oils and water.
- The solids are handled by a series of augers to transport the solids to a catch tank that is placed next to the Package skid
- The liquids catch tank is split for separation of oil and water
- Each side of the tank is emptied independently by its own dedicated pump controlled by automatic float switches
- The augers, centrifuge and feed pump are controlled by a HMI (Human Machine Interface) on the air-conditioned temperature controlled VFD (Variable Frequency Drive) cabinet and the back drive is driven by a hydraulically actuated Rotodiff drive controlled by the hydraulic unit.
A Practical Design and Its Works
Some details behind the Centrifuge's design include:
- The rotating assembly consists of a cylindrical, stainless steel bowl, solids-conveyor assembly, and ancillary components
- The bowl consists of a straight cylindrical section followed by a tapered section leading to the solids discharge point
- The bowl is driven through the solids-end hub, which is fitted to a drive sheave
- The bowl ends are fitted with roller bearings. Grease fittings are installed for periodic lubrication
The wet slurry enters the bowl through a concentric, stationary feed tube. On reaching the rotating conveyor, the slurry is accelerated to bowl speed where sedimentation of solids occurs on the wall of the bowl.
The conveyor rotates in the same direction as the bowl but at a slightly different speed. The solids are conveyed towards the conical end of the bowl.
Residual liquid is drained from the solids as they convey up the conical section toward the solids discharge ports. Separation takes place over the entire length of the cylindrical bowl.
Adjustable weir plates in the liquids-end hub control the pond depth. This establishes the radius at which liquid leaves the bowl. The liquid is discharged over the weir plates and drains toward the liquids discharge chute. Lighter liquid, like oil, separates from lighter effluent and discharges through oil discharge pipes fitted into the liquid head.
Why Use a 3-Phase Centrifuge?
By using a 3-phase centrifuge, the client can speed up their oil recovery process much faster than your typical separation using tanks this allows them to process more incoming produced water which gives them the water they need to frac the next well.
If they cannot treat water fast enough then they must buy water from other sources.
The solids are dewatered enough to pass paint filter and therefore decreases the cost for disposal.
In the past the solids were pulled off the bottom of the separator tanks via vacuum truck and hauled off for disposal. This sludge sometimes can contain up to 70% water by volume. This water is now staying on site and further treated for reuse.
The oil which sometimes had to have chemical treatment to enhance separation is now being separated through the three-phase unit without any chemical treatment and falling into the BS&W criteria for clean sellable oil.
