Oil & Gas Research
Mineral oxychloride in oil and gas operations, hydroxyl radical ions for stripper wells, and process biofilm control.
The oil and gas studies in the D&Z Worldwide research library cover stripper-well output, hydrogen sulfide removal and process biofilm control with mineral oxychloride chemistry. In a February 2020 field study on four wells in Pecos County, Texas, DZ 9450 lifted production from one or two barrels per day to fifteen, for under $100 per day in chemical cost.

Applications
Where does mineral oxychloride fit in oil and gas?
Increase stripper-well output
Hydroxyl radical ions from DZ 9450 attack the hydrogen sulfide and biofilm and destabilize the paraffin that restrict flow in low-producing stripper wells.
Control process biofilm
Biofilm protects pathogens across oil & gas production and process applications. DZ 9966 provides oxidative power to destroy EPS and remove biofilm.
The opportunity
Why do stripper wells matter?
770,000+US stripper wells
11.3%Of US oil production
8.3%Of US gas production
50–70%Of their oil left unrecoverable
A stripper well is an oil or gas well averaging 15 barrels per day or less — typically just 1 to 2. According to an oil-and-gas industry association, more than 770,000 US stripper wells together account for 11.3% of US oil and 8.3% of US gas. Yet 50 to 70% of the oil beneath them stays unrecoverable, held back by low reservoir pressure, poor permeability, and paraffin and asphaltene deposits.
DZ 9450 ROS reacts with H₂S, iron sulfide, biofilm and bacteria, acts as an emulsion breaker and micro-flocculant for produced water, and destabilizes paraffin and asphaltene — freeing flow paths near the wellbore.
Field study — Pecos County, TX
From 1–2 bbl/day to 15 bbl/day.
In a February 2020 field study on four wells in Pecos County, Texas, treating with DZ 9450 lifted production from 1–2 barrels per day to 15 barrels per day for less than $100 per day — roughly 5 gallons per day into the casing yielded 15 barrels per 12 hours.
- H₂S eliminated in both the gas and liquid streams.
- Produced water showed no detectable iron, bacteria or H₂S.
- Output increase held for under $100/day in chemical cost.
Side-by-side
Treated well vs. control (June 2016 stimulation).
| Measure | Well 10 — DZ 9450 | Well 12 — control |
|---|---|---|
| Estimated production | 33.5 bbl/day | 19.5 bbl/day |
| Production gain | +72% | — |
| Treatment time | 4 hours | 4–7 days |
| Material cost | $9,600 | $11,100 |
| Bottle-test bacteria | <1K CFU | <10K CFU |
Wet scrubbing — H₂S
How is H2S removed from sour gas?
In a Houston study, a natural-gas stream carrying 2,000 mg/L H₂S plus 5% CO₂ was completely stripped of H₂S. The scrubber ORP shifted from −150 mV to +100 mV, and the only residuals left behind were inert sulfates.
- Complete H₂S elimination from a sour-gas stream.
- Treatment cost of $0.0040 per pound of H₂S removed.
- Only inert sulfate residuals — no hazardous by-products.
Natural gas is classed as "sour" above 10 ppmv H₂S. On the emissions side, SO₂ comes mostly from power plants (73%) and industry (20%).
Questions
Common questions — oil & gas
How much can DZ 9450 raise stripper-well output?
In the Pecos County, TX study, production rose from 1–2 bbl/day to 15 bbl/day for under $100/day. In a June 2016 side-by-side stimulation, the treated well produced an estimated 33.5 bbl/day versus 19.5 for the control — a 72% gain — in 4 hours instead of 4–7 days and at lower material cost.
Does it remove H₂S from produced water and gas?
Yes. In the Pecos County wells, H₂S was eliminated in both gas and liquid, with no detectable iron, bacteria or H₂S in the produced water. In a Houston wet-scrubber study, 2,000 mg/L H₂S was fully removed at $0.0040/lb, leaving only inert sulfates.
How does it improve flow near the wellbore?
DZ 9450 ROS reacts with H2S, iron sulfide, biofilm and bacteria, breaks produced-water emulsions, and destabilizes paraffin and asphaltene, the deposits that help make 50 to 70% of a stripper well's oil unrecoverable. Clearing that material from the pore space and the near-wellbore area addresses the same restrictions, alongside low reservoir pressure and poor permeability, that hold back production from wells averaging 15 barrels per day or less.
