Dry Add Units in Elk City, OK
Elk City sits along the I-40 corridor in Beckham County, right at the western edge of the STACK play where it begins to blend into the broader Anadarko Basin. The town has long served as a staging point for oilfield equipment moving in and out of western Oklahoma, and crews working pads around Beckham, Roger Mills, and Custer Counties often run their logistics through here. 4S Chemicals LLC supplies dry add units to operators in this stretch, replacing iso tank hauling with on-site dry polymer storage and metered dosing.
A dry add unit gives a frac crew a way to store and inject dry polymer directly into the frac stream without trucking liquid concentrate across long distances. For jobs running west of the main STACK core toward Elk City and Sayre, that distance is exactly where trucking costs start to add up the most.
Why Elk City Crews Use a Dry Add Unit
Pads around Elk City tend to sit further from the main supply hubs than locations closer to OKC or Weatherford, which makes every iso tank trip more expensive in both time and fuel. Longer haul distances also mean more exposure to weather delays and road conditions along I-40 and the connecting county roads.
The 4S Chemicals dry add unit has a 20 ft footprint, small enough to pre-stage an entire job on location before the first stage pumps. Because the unit removes iso tanks from the supply chain, it cuts transportation cost by roughly 75% compared to standard liquid concentrate logistics. For crews working the western edge of the STACK around Elk City, that reduction in trucking has a bigger impact than it does closer to the basin’s center, simply because the haul distances are longer to begin with.
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
- 45 degree sloped bottom with slide gate
- Beam scales with monitor for accurate load tracking
- C.P. meter in every unit, values recorded during each stage
- Cloud-based system for remote data sharing and monitoring
- Touch screen, computer-controlled inline operation
Because the unit logs stage data automatically through its cloud-based system, dosage records stay available to the company man or engineering team even on locations further from town where cell coverage and support access can be inconsistent.

Real-Time Water Analytics on Location
Water sourced for pads around Elk City and Beckham County can shift in quality depending on the draw point, particularly on locations pulling from smaller rural sources. The dry add unit runs a water slip stream through electronic probes that track quality continuously, so dosage can be adjusted mid-stage instead of after a friction reducer issue shows up downhole. 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 is compared against polymer performance in real time, which lets the system flag cause-and-effect patterns before they become a problem on the back half of a stage.
Dry Add Unit Paired with FRXD
Crews working west of the STACK core around Elk City commonly pair the dry add unit with FRXD, the company’s non-PAM friction reducer. The dry add unit handles precise on-the-fly dosing, while FRXD reduces flow resistance without the extra breakers traditional polyacrylamide-based products require. FRXD breaks down on its own with time and temperature and resists iron buildup, which matters in formations across Beckham and Roger Mills Counties where water chemistry can vary from one pad to the next. For longer-haul jobs out toward Elk City, fewer moving parts in the chemical program means fewer things that can go wrong on a remote location.
Service Area Around Oklahoma City
4S Chemicals is based in Norman and regularly mobilizes west along I-40 to reach operators around Elk City. Coverage includes:
- Beckham County (Elk City, Sayre, Erick)
- Roger Mills County (Cheyenne, Hammon)
- Custer County (Clinton, Thomas)
- Washita County (Cordell, Bessie)
- Dewey County (Camargo, Vici)
For pads further west or south of this footprint, call ahead to confirm mobilization timing. The compact size of the unit makes it practical to move between locations spread out across rural Beckham and Roger Mills County roads.
Frequently Asked Questions
Why does a dry add unit matter more for jobs around Elk City than closer to OKC?
Haul distances are longer on the western edge of the STACK, so removing iso tank trucking saves more time and cost the further a pad sits from the main supply hubs.
How far is Elk City from 4S Chemicals' base in Norman?
Elk City is roughly 110 miles west of Norman along I-40, within the company’s standard mobilization range for STACK play jobs.
Does the dry add unit work on remote rural locations with limited cell coverage?
Yes. The unit logs and stores stage data through its cloud-based system, so dosage records remain available once a connection is restored.
Can dosage be adjusted while a stage is already pumping?
Yes. Dosage adjusts on the fly between .25 and 4.0 GPT without stopping the job.
Is the dry add unit suited for jobs pulling water from smaller rural sources?
Yes. The water slip stream continuously tracks quality and feeds the data back for real-time polymer adjustments, which matters most when water sources vary pad to pad.
