Oilfield Chemicals & Water Treatment
Field-specific production chemistry, water treatment and EOR screening for mature oilfields.
Karamay Energy supports mature-oilfield operators with field-specific production chemistry, water treatment and laboratory-backed formulation support from Karamay ZhengCheng.
Each programme begins with the field problem. We review production, water, fluid and facilities data to select or adjust the appropriate chemistry, then support a controlled, measurable pilot where justified.
Laboratory, Formulation & Manufacturing Support
Karamay ZhengCheng in Karamay, Xinjiang, provides formulation, manufacturing and laboratory support for practical oilfield-chemistry programmes. Its technical team can evaluate fluids and water, adjust formulations and provide specialist guidance where required.

Field-Specific Chemistry & Reservoir Screening
Karamay Energy works with established technical partners to combine laboratory evaluation, specialist chemical formulation and practical field experience in selecting treatments suited to specific reservoir, fluid, water and operating conditions. Our objective is to deliver practical, measurable improvements through field-specific solutions rather than generic chemical programmes.
Chemistry Selected for the Field
Treatment selection begins with actual field conditions—production behaviour, produced- and injection-water quality, crude characteristics, temperature, salinity and facilities constraints. Working with our established technical partners, Karamay Energy coordinates compatibility assessments, field-specific formulation adjustments and controlled pilot programmes where appropriate.
Production Chemistry & Seperation
Karamay Energy provides access to specialist, field-specific production chemistry through its technical partnerships, supported by established formulation, manufacturing and laboratory capabilities. Treatments are selected to address practical production, separation, water-handling and asset-integrity challenges.
​
Our chemical formulations address:
• emulsion destabilization
• water clarification and oil removal
• mineral scale and corrosion inhibition
• biocide and bacterial control
• clay and shale stabilization
• paraffin and gas hydrate mitigation
• heavy oil viscosity modification
• accelerated oil-water separation
These chemicals are engineered to remove bottlenecks and protect subsurface equipment through targeted formulation.
​
EOR & Polymer-Flooding Screening
Polymer flooding and other chemical-EOR options are considered only where reservoir conditions, water quality, injectivity, facilities and pilot economics support a credible field case.
​
Our chemical range includes:
• customized polyacrylamide (PAM) systems
• ultra-high-molecular-weight polymers
• mobility control agents
• conformance and profiling chemistry
• cross-linked water shutoff systems
• technical hydration and preparation support
• site-specific formulation adjustments
Testing in specialized laboratories is essential to validate performance before field deployment.
​
​
Produced-Water Treatment & Injection-Water Quality
Produced-water treatment, de-oiling, solids removal and injection-water compatibility are reviewed against the operator’s separation, disposal and injection requirements. Treatment may include demulsification, de-oiling, biocide, scale and corrosion control, selected through water analysis and operating data.
Heavy-Oil Flow & Production Support
Heavy-oil programmes begin with the practical flow, separation and reservoir constraint. Depending on the field data, technical options may include viscosity reduction, demulsification, near-wellbore treatment, scale control, water shut-off or thermal-chemical screening.
​
Our chemical applications provide:
• chemical viscosity reduction
• precise emulsion management
• near-wellbore chemical stimulation
• scale and inorganic deposit control
• chemical water-shutoff treatments
• profile modification and conformance
• thermal-chemical synergy support
• fluid conditioning for surface handling
Chemical selection is based strictly on laboratory analysis of the crude and brine properties.

Hydraulic-Fracturing Fluid Support
Karamay Energy provides technical chemical additives for hydraulic fracturing, supported by manufacturing expertise. Our portfolio includes:
• high-efficiency friction reducers
• dry-concentrate polymer systems
• rapid-hydration technology for continuous mixing
• permanent clay stabilizers
• water compatibility and brine analysis
• chemistry for produced-water fracturing
• functional fracturing-fluid additives
Drilling, Completion & Workover Fluids
Karamay Energy offers a range of specialised additives and formulation support for drilling, completion and workover fluid systems through its technical partnerships. Each programme is assessed against the operator’s formation, characteristics, fluid properties, water chemistry and operating requirements.
Our product range includes:
• fluid-loss and filtration control agents
• specialized lost-circulation materials
• high-lubricity drilling additives
• shale inhibitors and stabilizers
• PAC and CMC polymer systems
• drilling fluid performance additives
• completion and packer fluid chemistry
• chemical workover and service fluids
Selection is dictated by formation lithology and fluid design.
Laboratory Testing & Formulation Support
Laboratory testing, fluid analysis and formulation adjustment help ensure the chemistry is suitable for the specific crude, water, reservoir and operating conditions. Where justified, treatment performance can then be assessed through a controlled field pilot.
Chemistry Across Field Operations
Field-specific chemistry can support production, drilling, completion, water management and well-integrity requirements across a mature asset. The right application is selected from the field data and operational objective.
Our chemistry is refined for:
• reservoir and production science
• drilling and completion operations
• chemical EOR program execution
• production restoration activities
• produced-water management cycles
• well and equipment integrity
• field-wide redevelopment projects
• real-time performance monitoring
Applying these targeted formulations ensures that chemical science supports your primary asset optimization and recovery objectives.
Established Manufacturing & Technical Support
Through our established technical partnerships, Karamay Energy provides access to more than three decades of oilfield-chemistry manufacturing, laboratory and specialist technical experience. We combine these capabilities with field assessment, formulation adjustment and practical technical support to develop solutions tailored to the operating requirements of mature oilfields in Kazakhstan and Central Asia.
