Dry Add Units for Oklahoma City Frac Operations
Oklahoma City sits at the center of one of the busiest drilling corridors in the country. Operators working the SCOOP and STACK plays, along with the wider Anadarko Basin, run completion crews out of OKC because the location gives quick access to pad sites stretching from Canadian County down through Grady and McClain Counties. 4S Chemicals LLC, headquartered just south of the city in Norman, supplies dry add units to crews working this region, cutting down on iso tank congestion and trucking costs while keeping polymer dosing accurate from the first stage to the last.
A dry add unit lets a frac crew store, meter, and inject dry polymer directly into the frac stream without hauling liquid concentrate to location. For operators running multiple pads across the OKC metro and the surrounding counties, that difference shows up directly in the trucking budget and the time it takes to get a job staged
Why Oklahoma City Crews Use a Dry Add Unit
Liquid polymer concentrate takes up a lot of road space. A single frac job can call for dozens of iso tank loads, and every one of those trucks has to navigate the same county roads, lease roads, and highway access points that the rest of the crew uses to get equipment on location. Switching to dry polymer storage and on-site mixing removes most of that traffic.
The 4S Chemicals dry add unit has a 20 ft footprint, small enough that an entire job can be pre-staged on location before pumping starts. Because the unit eliminates iso tanks, it cuts transportation cost by roughly 75% compared to liquid concentrate hauling. For crews running back-to-back pads in the OKC area, that means fewer trucks on the road, less time spent waiting on deliveries, and a cleaner location overall.
Equipment Specs
- 20 ft footprint, fully pre-stageable on site
- 300 gallon working tank, 316 stainless piping
- 300 gallon minimum in/out, dust-free operation
- Dosage rate adjustable from .25 to 4.0 GPT, on the fly
- Poly tote bulk storage, 2,500 lbs capacity

Real-Time Water Analytics on Location
Water quality changes from pad to pad and sometimes from stage to stage, especially when a crew is pulling from different sources around the OKC metro. The dry add unit’s water slip stream runs electronic probes that track quality continuously, so the polymer dosage can be adjusted while pumping instead of after the fact. Measurements taken across the full water volume include:
- Dissolved oxygen
- Water temperature
- pH
- ORP (oxidative redox potential)
- FAC (free available chlorine)
- Conductivity
- Resistivity
- Polymer viscosity and pressure profile
That data gets compared against polymer performance in real time, which lets the system flag cause-and-effect patterns before they turn into a friction reducer problem mid-stage.
Dry Add Unit Paired with FRXD
Most crews running 4S Chemicals’ dry add units pair them with FRXD, the company’s non-PAM friction reducer. The two are built to work together: the dry add unit handles precise, on-the-fly dosing, and FRXD reduces flow resistance without the breakers that traditional polyacrylamide-based products require. FRXD also breaks down with time and temperature on its own and resists iron buildup, which matters in formations where iron content can leave agglomerations in the wellbore. Crews working the Anadarko Basin around Oklahoma City often deal with variable water chemistry, and the FRXD-dry add combination is built to handle that without slowing down the stage.
Service Area Around Oklahoma City
4S Chemicals operates out of Norman, roughly 20 minutes south of downtown Oklahoma City, putting the company within quick reach of pad sites across the metro and the surrounding play. Coverage includes:
- Oklahoma County and the OKC metro
- Canadian County (El Reno, Yukon, Mustang)
- Cleveland County (Norman, Moore)
- Grady County (Chickasha, Tuttle)
- McClain County (Purcell, Blanchard)
- Logan County (Guthrie, Edmond)
If a pad falls outside this list, call the team directly. Dry add units mobilize across the broader STACK and SCOOP footprint as job schedules allow.
Frequently Asked Questions
What is a dry add unit used for in fracking?
A dry add unit stores dry polymer in bulk and meters it directly into the frac stream on location, removing the need to haul pre-mixed liquid polymer concentrate to the pad.
How much does a dry add unit reduce trucking costs?
Eliminating iso tanks through dry polymer storage cuts transportation cost by approximately 75% compared to standard liquid concentrate logistics.
Can the dosage rate be changed during a stage?
Yes. The 4S Chemicals unit allows on-the-fly dosage adjustments between .25 and 4.0 GPT without stopping the job.
Does 4S Chemicals serve operators outside Oklahoma City?
Yes. The company is based in Norman and covers the wider OKC metro, Canadian, Cleveland, Grady, McClain, and Logan Counties, with mobilization available across the STACK and SCOOP plays on request.
Is the dry add unit compatible with other friction reducers besides FRXD?
The unit is built to run FRXD for the best dosage accuracy and performance, though it can be configured for other dry polymer products on request.
