EQUIPMENT REFERENCE
HOW IT FITS THE OPERATION
Protect equipment. Manage the production stream.
Production chemicals address different operating challenges, including corrosion, scale, separation and water-related treatment. The treatment objective needs to be understood in the context of the stream and the equipment it passes through. A product category alone does not establish whether a particular formulation is suitable.
NOVA’s chemical offering is therefore considered alongside the operating issue and the delivery arrangement. Treatment selection, injection equipment and the wider process should be discussed together. This keeps the chemical programme connected with the practical conditions of the facility instead of treating the product as a standalone consumable.
APPLICATION CONTEXT
Asset protection
Corrosion and scale enquiries concern the conditions experienced by the equipment and the production stream. Existing observations and treatment history provide context for identifying the protection objective and the next technical questions.
APPLICATION CONTEXT
Oil and water handling
Emulsion and water-treatment enquiries are connected with the intended separation or water-quality outcome. The process stage and the destination of the treated stream help frame the discussion.
APPLICATION CONTEXT
Treatment delivery
A chemical treatment must also be considered in terms of how it reaches the process. Injection equipment, handling arrangements and current product documentation form part of the practical supply conversation.

ENHANCED CATALOGUE REFERENCE
01 / OIL TREATMENT
Demulsifiers & desalter treatment
The PC D Series covers emulsion-breaking applications, with different references for different crude characteristics. The catalogue identifies PC D 1505 for higher-API oil, PC D 9306 for heavier, lower-API oil, and PC DS 301 and PC DS 9301 for desalters. The aim is to support oil–water separation; the formulation is selected through laboratory and field testing.

02 / ASSET PROTECTION
Corrosion inhibitors
The range includes water-soluble, oil-soluble and dispersible film-forming products. PC CI 2101 is described for carbon-dioxide corrosion in oil–water mixtures, while PC CI 2134 is listed for flowlines and trunk lines carrying crude or gas. The catalogue also describes controlled-release DURACAPS CI for downhole treatment. Match the product to the corrosion mechanism, fluid conditions and treatment arrangement.

CATALOGUE / PAGE 24
03 / DEPOSIT CONTROL
Scale inhibitors
Mineral deposits can become a treatment concern in production and water-handling systems. The catalogue lists PC SI 3404 and PC SI 3405 for inhibiting carbonate and sulphate scale formation. DURACAPS SI is presented as a controlled-release downhole option. These references provide a starting point for reviewing water chemistry, deposition conditions and the appropriate treatment approach.

Biocides
The PC B range includes products for water-injection systems and sulphate-reducing bacteria control. Examples include PC B 1110, PC B 1111 and PC B 1100, with additional biocide references elsewhere in the catalogue. Product selection is tied to the organisms and conditions in the system; the catalogue calls for testing before a recommendation is made.

05 / PROCESS STABILITY
Antifoams & defoamers
Foam-control products cover several process duties. PC DF 100 is listed for water injection, PC DF 200 for water-treatment applications, and PC DF 900 for cementing, completion and workover operations. PC DF 30 and PC DF 300 are referenced for gas–oil separators and refinery vacuum units. Selection depends on the process fluid and the location of the foaming problem.

The catalogue is an existing reference document (revision May 2012). Product names are included to help identify an enquiry. Final selection, dosage and compatibility require current product information and application-specific testing.
Application first.
Start with your operating conditions, technical requirements, and project priorities.
Production treatment
Explore corrosion inhibitors, scale inhibitors, biocides, emulsion breakers, and water-treatment chemicals.
Application support
The original application scope includes drilling fluids, mud/cement spacers, completion/workover fluids, stimulation fluids and chemical enhanced-oil-recovery enquiries. Field service and technical backup, including specialist chemistry or research support where agreed, can form part of the project scope. Define the testing, documentation and field assistance required. Chemical enhanced oil recovery is distinct from produced-water recovery and reuse.

Discuss the mud or fluid system, temperature, compatibility, handling requirements and required technical documentation. Catalogue references identify the enquiry; they do not replace current product data or application testing.
Plan the treatment and its delivery together
Start with the production issue
Describe the issue you are trying to address, where it occurs and how it affects the operation. Existing treatment records, fluid information and observations from the field can provide context for a technical discussion. Separate measured information from assumptions, and explain whether the enquiry concerns a new treatment programme, an existing product or a change in operating conditions. Product suitability and dosage need application-specific review rather than selection from a product name alone.
Include the injection arrangement
The way a chemical is stored, transferred and injected forms part of the requirement. Share the proposed injection point, available utilities, control expectations and relevant equipment information. Where an injection skid or pump is involved, identify the existing arrangement and the boundaries of the requested supply. Provide handling and site requirements with the enquiry, and confirm product documentation, material compatibility and the agreed treatment approach before making a purchasing decision.
