Oilfield Chemicals Manufacturer: Products, Applications, Quality Control, and Purchasing Guide

A trustworthy Oilfield Chemicals Manufacturer ought to offer greater than a general product catalogue or a competitive quote. Oil and gas companies, drilling contractors, well-service providers, chemical distributors, and engineering firms also require products that will meet field requirements, consistent batch quality, measurable specifications, technical support, secure packaging, and reliable delivery.

Oilfield chemicals are utilized in various stages of drilling, completion and cementing, stimulation, production, enhanced oil recovery, produced-water treatment, corrosion control, scale prevention, demulsification and sludge treatment. Reservoir temperature, water salinity, hardness, pressure, crude-oil composition, formation mineralogy, shear conditions, equipment design and other chemicals already in the system can all affect their performance.

Therefore, buyers need to choose oilfield chemicals based on lab testing and field performance and not name or price alone.

• Salt-resistant polymer grades

Potential applications include:

• Drilling-fluid viscosity control
• Shale encapsulation
• Friction reduction
• Enhanced oil recovery
• Produced-water clarification
• Sludge dewatering
• Profile control
• Water shutoff

Important performance parameters include molecular weight, hydrolysis degree, charge density, thermal stability, salinity tolerance, shear resistance, dissolution time, and viscosity retention.

PHPA for Drilling Fluids

Partially hydrolyzed polyacrylamide, often abbreviated as PHPA, is widely used in water-based drilling fluids.

It may help:

• Encapsulate shale
• Reduce clay dispersion
• Improve wellbore stability
• Support cuttings transport
• Increase viscosity
• Reduce fluid loss
• Improve solids-control efficiency

PHPA should be selected according to formation mineralogy, drilling-water quality, temperature, salinity, calcium concentration, and the complete mud formulation.

HPAM for Enhanced Oil Recovery

Partially hydrolyzed polyacrylamide is also used in polymer flooding for enhanced oil recovery.

It can increase injection-water viscosity and improve the mobility ratio between water and oil.

Potential benefits include:

• Reduced water fingering
• Improved reservoir sweep
• Delayed water breakthrough
• Reduced channeling
• Increased oil displacement
• Improved recovery from mature reservoirs

EOR-grade HPAM should be evaluated for injectivity, molecular weight, salinity tolerance, hardness resistance, thermal stability, adsorption, filterability, and mechanical degradation.

Friction Reducers

Friction reducers are used to lower pressure loss during high-rate fluid pumping.

Applications may include:
