Production
Getting more from every well
We qualify the well before the job is booked, blend the chemical, run the pump, and measure what came back against baseline.

The short version
OneCor treats producing wells across the basins we serve, with pumping crews out of Williston, North Dakota, and Odessa, Texas. Our engineers review the well file, water analysis, and any deposit analysis. We blend the chemical, bring the pump, and compare production after the job against baseline.
Common problems
Job types
As an oil well matures, issues begin to show up, from rod and tubing scale failures to a decline curve that is sharper than expected. Whether you need heated fluid, an acid soak for near-wellbore skin, or a designed diverter job to reach perforations that need attention, we can help.
| If you're seeing… | What we'd run | Type |
|---|---|---|
| Lower production or pump intake issues | Before you call a rig, call us. An acid job down the backside may free up debris in the pump. If you're worried about the pump, ProSurge brings the dissolving power of acid with less harm to mild metals. | Batch |
| ESPs losing run time to scale | Maintenance treatments with ProSurge dissolve scale as it forms, so the ESP runs well for as long as possible. | Maintenance |
| Production falling faster than the decline curve | An acid soak for near-wellbore skin, or a designed diverter job to reach the perforations that need attention. | Uplift |
| Rod and tubing scale | Our hot oiler brings an acid pup. We pump the acid, then heated flush water behind it for displacement, without risking shearing the tubing from the tubing anchor. | Batch |
| A high-rate flush already on the schedule | Spot HCl on the way out. Once the sand is out of the way, it's a good time to acid-wash the perforations. Two workhorses, more uplift. | Uplift |
| Scale building up in flowlines | Batch treatment with a pump truck, or continuous application where the problem is severe, at a reduced cost compared to a traditional scale inhibitor. | Continuous |
| Rising injection pressure on a disposal well | An upfront acid job to bring injection pressure down, then continuous application to keep it down. | Continuous |

Engineering
Maximize every job
High-rate clean-outs have a strong record on their own, and pairing that rate with the right chemistry has worked better still. Chemical is a small share of the total job cost and changes the outcome. That's why engineering qualifies candidates before anyone books the job.
If it's production uplift you're looking for, our in-house engineering team will review well files to help identify the best candidates and write up the procedure that fits your goals and budget.
Qualify
Engineering reviews well history and current production and tells you whether the job is worth doing. Sometimes it isn't.
Design
Chemistry, concentration, volume, staging, and rate, built around what fits your well
Pump
Our equipment and our crew, with a field specialist on location and data acquisition running.
Measure
Follow-up reporting compares baseline to post-treatment production, and the evaluation explains why the well responded.
From 3.6 to 52 barrels a day, without a re-frac
A 2005 well, down since April 2022 with a stuck pump. We designed an acid and chemical treatment, then supplied, hauled, stored, and pumped it with our own equipment.
Equipment
Our pump fleet
Our diversified equipment means one call can handle your well intervention needs, for horsepower and chemical. Rate runs from 0.25 to 10 barrels per minute, so a slow flush is available where a lower rate is the right call.
Rate and pressure are recorded on every job. Pumping crews run out of Williston, ND, and Odessa, TX, and go as far as the job needs.
ProSurge: acid strength, easier on metal
Our synthetic acid reacts at about the same rate as 15% HCl, with a slight delay so it doesn't spend the moment it's pumped. It's far less corrosive on standard metals, vapor-free, and safer to handle. Used for backside treatments, ESP maintenance, flowline descaling, and disposal wells.

Dispatch answers 24/7
What job is best for targeting uplift?
It depends on what's limiting the well. Our engineers start with your well file, water analysis, and any deposit analysis. For many wells, a backside treatment of one drum to one tote of product is the lowest-cost place to start. If a high-rate flush is already planned, spotting HCl on the way out adds a second workhorse.
Why does production drop off in an older well?
Reservoir pressure falls over time, and mineral scale coats the formation face. Both restrict flow. Acid treatment dissolves the scale and reopens the fractures, and follow-up reporting shows how much production came back against baseline.
Can you treat a saltwater disposal well?
Yes. Disposal wells lose intake capacity as solids and chemicals plug the formation, sometimes dropping from 10,000 barrels a day to 7,500. We pump treatment to restore intake, using our own chemical and our own equipment, and continuous application afterward can keep injection pressure down.
Do you supply the chemical and the pump?
We do both. We blend our own chemical and run our own pumps, including a combination unit that heats and pumps from a single truck. Most pumping companies buy chemical from a supplier, and in some cases that supplier is us.
Will you tell me if a job isn't worth doing?
Yes. Qualifying the candidate is the first step, and part of engineering's job is identifying wells where the treatment won't pay back. A job that doesn't return the investment costs you twice.
