Build drilling and completion fluids around operating conditions
CMC and PAC are used for viscosity and filtration control, while HEC is evaluated for completion, workover and fracturing fluids where brine compatibility and clean rheology matter. AMPS is primarily purchased as a functional monomer for polymers designed for salt, calcium and temperature tolerance.
Calcium chloride and potassium formate can supply density and water-activity control in completion or workover brines. Specify target density, temperature, crystallization point, corrosion program, solids limits and compatibility with elastomers, polymers and formation fluids.
Match sour-gas and dehydration chemistry to the process
MEA triazine is a liquid H₂S scavenger for contact-tower, injection and batch-treatment systems. Active content, pH, density, residual amine, formaldehyde-related impurities, residence time, H₂S loading and spent-fluid handling should be evaluated together.
TEG is the standard glycol considered for continuous natural-gas dehydration because of its operating properties and regeneration performance. DEG can be used in selected dehydration or solvent duties, but its toxicity and process-specific limitations require careful review.
Write an RFQ that supports technical qualification
For CMC and PAC, state the relevant API 13A or ISO 13500 type and required viscosity or filtration data. For HEC and AMPS-based systems, add salinity, divalent ions, temperature and hydration or polymerization requirements. For brines, provide density, purity and low-temperature needs.
For MEA triazine and glycols, request active or purity, water, acidity or pH, density, color and applicable impurity limits, together with SDS, COA, package and transport status. Laboratory compatibility and field trials remain necessary before changing a treatment program.
