We offer a comprehensive portfolio including DMDAAC, PDMDAAC (liquid and exclusive bead/powder forms), and Polyacrylamide (PAM) series, with an annual production capacity of over 50,000 tons to meet diverse industrial needs.
Ewooan Oilfield Chemical Additives are a premium range of functional chemical auxiliaries developed specifically for the entire oil and gas exploration and production value chain. The product line comprehensively covers core engineering scenarios including onshore oilfields, offshore platforms, deep wells, horizontal wells, complex formation drilling, mud performance control, reservoir protection, fracturing stimulation, workover operations, and secondary/tertiary water injection for stable production.
The full range comprises four flagship categories: Cationic Clay Stabilizing Agent, Cationic Clay Stabilizer for Oilfield Drilling, Polymer Clay Control Additive for Drilling Fluids, and Oilfield Water Injection Chemical Additive.
These products address persistent industry challenges faced globally: clay hydration swelling, wellbore instability and collapse, drilling fluid system disorders, excessive solids content, uncontrolled fluid loss, formation pore blockage, abnormal water injection pressure, uneven water flooding, declining crude oil recovery rates, and high incident rates during operations.
As indispensable fine chemical consumables for oilfield engineering, this product series is widely suited for bulk procurement, long-term stocking, and project-specific customisation by major oil and gas production groups, drilling engineering contractors, oilfield service companies, and block operation enterprises. These products are essential for safe construction, low-cost operation and maintenance, and stable production capacity in oilfield operations.
The vast majority of oil and gas reservoirs worldwide are water-sensitive formations, rich in highly active clay minerals such as montmorillonite, illite, and kaolinite. During drilling fluid invasion, workover fluid contact, and long-term water injection development, clay particles readily absorb water, hydrate, swell, disperse, and migrate.
This directly causes a series of serious engineering problems: wellbore instability, borehole shrinkage, caving and collapse, stuck pipe, difficult tripping operations, drilling fluid viscosity loss of control, soaring solids content, poor mud cake quality, irreversible formation permeability damage, rising water injection well pressure, water breakthrough in oil zones, and rapid production decline. These issues not only significantly increase operational difficulty and safety risks but also result in huge rework costs, consumable losses, and production shortfalls.
Our entire cationic oilfield chemical series is produced using proprietary modified polymerisation technology, featuring high-density cationic active groups that rapidly complete charge neutralisation, particle adsorption, cross-linking consolidation, and film-forming sealing – inhibiting clay hydration reactions through both physical and chemical mechanisms. The products resist high temperatures, high salinity, high mineralisation, and high water pressure impacts. They are suitable for extreme conditions including fresh water, salt water, supersaturated brine, and complex multi-formation environments. They are non-corrosive, non-toxic, cause no secondary formation damage, and offer excellent compatibility.
Formation protection from the source, risk control at the root: The entire series uses cationic polymer formulations that inhibit clay hydration swelling, dispersion, and migration from the source, stabilise wellbore walls, protect reservoirs, significantly reduce downhole engineering incident risks, and ensure continuous and stable construction.
Full adaptation to complex conditions: Resistant to high temperature, high salt, erosion, and mineralisation. Suitable for deep wells, horizontal wells, complex collapsing formations, high-water-content formations, and difficult water injection conditions. Versatility and adaptability far exceed ordinary oilfield auxiliaries.
Cost reduction, efficiency improvement, and production enhancement: Effectively shortens drilling cycles, reduces accident rework, lowers well washing and maintenance frequency, and stably improves water injection efficiency and crude oil recovery rates – comprehensively reducing overall oilfield development and operation/maintenance costs.
Strong compatibility, ready to use: Perfectly compatible with various water-based and oil-based drilling fluids, fracturing fluids, and water injection systems. No equipment modification or existing process adjustment required – minimal on-site adaptation cost.
No formation damage, compliant and safe: Non-toxic, non-corrosive, no secondary precipitation, no reservoir contamination, no impact on crude oil quality. Meets global oilfield chemical safety standards and adapts to all formal oil and gas engineering project acceptance procedures.
Stable supply, customisable: Self-developed and self-produced from source factory with ample stock availability. Supports formulation customisation for different geological conditions and construction processes, meeting differentiated, bulk, and long-term strategic cooperation procurement needs.
Ewooan has been deeply engaged in the R&D, production, and engineering application of polymer oilfield chemical auxiliaries for over a decade, with a dedicated focus on the precision manufacturing of high-end series including clay stabilisation, drilling fluid regulation, water injection stabilisation, and reservoir protection. We operate an independent standardised chemical production base, automated polymerisation reaction production lines, precision batching control systems, and professional oilfield chemical testing laboratories, with fully integrated R&D, production, testing, sales, and technical service capabilities.
For our four flagship products: Cationic Clay Stabilizing Agent, Cationic Clay Stabilizer for Oilfield Drilling, Polymer Clay Control Additive for Drilling Fluids, and Oilfield Water Injection Chemical Additive. We have established a stringent full-process quality inspection system. Every batch is rigorously tested for more than ten core technical indicators including solid content, cationic charge density, clay swelling inhibition rate, temperature and salt resistance, fluid compatibility stability, and formation adaptability. All batch data are fully traceable, quality is controllable, and indicators are compliant – eliminating batch differences, performance fluctuations, and substandard product shipments.
Over the years, our products have consistently served major domestic oil and gas fields, offshore platforms, and oilfield engineering projects in overseas markets including the Middle East, Southeast Asia, Central Asia, and Africa. We have accumulated extensive field application data and mature solutions for extreme conditions including high temperature, high salinity, complex formations, mature blocks, and high-end deep wells – with rich practical experience and high engineering recognition.
We provide global procurement customers with comprehensive full-chain professional services: pre-sales – geological and operational condition analysis, precise product selection, customised formulation, and construction solution optimisation; in-process – full quality control and batch testing tracking; after-sales – on-site technical guidance, commissioning support, problem diagnosis, and long-term technical follow-up. With solid technical accumulation, authentic engineering case histories, stable product quality, and a complete service system, every oilfield engineering procurement customer can make selections with confidence, use with peace of mind, and build long-term partnerships.
