A proprietary mud acid replacement formulated to disperse and dissolve silica and HCl-soluble solids and scales - with integrated iron control, anti-sludge, and non-emulsifying performance built in from the start.
STIMWRX lab analysis identified self-induced damage as a leading cause of production decline across a variety of wells and formations. High fluid mobility disturbs sensitive clays, causing them to migrate. Once mobilized, these clays act as binders - forming sludge that restricts production, plugs injection intervals, and fouls surface facilities.
Sustained decline that does not respond to conventional acidizing - often caused by clay sludge choking flow paths rather than simple scale buildup.
Frequent bailer runs and workovers that treat the symptom - mud inflow from open-hole laterals - without addressing the underlying clay mobilization driving it.
Sludge forming from entrained solids restricts injection intervals and fouls surface facilities - reducing sweep efficiency and increasing operating costs.
After iterative lab and field testing in collaboration with operators, STIMWRX developed MULTI-CLN™. It is a proprietary mud acid replacement formulated to disperse and dissolve silica and HCl-soluble solids and scales - while providing integrated iron control, anti-sludge, and non-emulsifying performance in a single-stage application.
Its silica-dissolving component serves as a hydrofluoric acid (HF) replacement, offering substantially lower corrosivity than HF - enabling safer and more effective wellbore and near-wellbore cleanup without compromise on performance.
Facilitates the dispersion of Oil Mineral Aggregates (OMA) - the primary mechanism behind sludge formation - then aggressively breaks down the resulting sand and clay deposits to restore flow paths.
Water-wetting additives break down hydrocarbon barriers, allowing the chemistry to penetrate deep into damaged zones. Controlled reaction rate ensures maximum reservoir contact rather than near-wellbore reaction.
Built-in iron control, anti-sludge agents, and non-emulsifying additives eliminate the need for multiple standalone additive packages - single-stage application, no pre-treatment required.
Dissolves silica without the extreme hazard of Hydrofluoric acid. Substantially lower corrosion profile protects wellbore integrity and enhances on-site safety for field crews.
Multi-lateral well on production since 2022. By 2024, significant and sustained production decline had made the asset uneconomical to operate. Multiple workovers were required, with bailer runs to manage persistent mud inflow from open-hole laterals to the heel.
Lab testing confirmed severe sludge build-up from mobilized clays (Kaolinite and Quartz) choking flow paths, combined with reduced interfacial tension impairing hydrocarbon recovery.
STIMWRX prescribed MULTI-CLN™ to penetrate deep into the reservoir, disperse OMA, break down clay binders, and restore permeability - in a single-stage application with no pre-treatment required.
Average monthly oil production increased 127.4% compared to the pre-treatment baseline, delivering a rapid return on investment and eliminating the need for further mechanical interventions. The operator was able to restore the well to economic production without a workover rig.
Equivalent silica and clay dissolution to traditional mud acid - lower corrosivity, safer execution, no compromise on results.
Single-stage application. Integrated iron control, anti-sludge, and non-emulsifying additives eliminated all pre-screening steps.
Oil Mineral Aggregate dispersion restored flow paths that bailer runs and workovers had repeatedly failed to clear.
MULTI-CLN™ is effective across both production and injection well applications - versatile for multilateral and waterflood assets.
Our technical team will analyze your well's mineralogy, production history, and damage mechanism before any chemistry is prescribed. We do not guess - we verify.
