How is PBTC applied in the oil field

In the oil field, PBTC (Phosphonobutane tricarboxylic acid) can be applied for various purposes, including scale and corrosion inhibition. Here are some common methods of applying PBTC in the oil field:

Injection into the Formation: PBTC can be injected directly into the oil reservoir or formation to inhibit scale formation and prevent mineral deposition. This helps maintain the permeability of the reservoir and improve production efficiency.

Surface Treatment: PBTC can be applied to the surface of equipment, pipelines, and storage tanks to prevent scale formation and corrosion. It is typically added to the water or chemical treatment process used for maintaining the integrity of the equipment and ensuring smooth operations.

Water Treatment: In oil field operations that involve water injection, PBTC can be added to the injection water as a scale and corrosion inhibitor. By treating the water before injection, it helps prevent scaling in the injection system, wellbore, and reservoir, thereby improving injectivity and enhancing oil recovery.

Fracturing Fluids: During hydraulic fracturing operations, PBTC can be included in the formulation of fracturing fluids to prevent scale deposition in the fractures and near-wellbore areas. It helps maintain fracture conductivity and prevents damage caused by scale buildup.

Rig and Production Facility Maintenance: PBTC can also be used as a component of corrosion inhibitors for protecting drilling rigs, production facilities, and associated equipment from corrosion. It is added to the water treatment or chemical dosing system to provide effective corrosion protection.

The specific application and dosage of PBTC will depend on factors such as the water composition, operating conditions, and the particular requirements of the oil field operation. It is important to consult with water treatment specialists or chemical suppliers who can provide guidance on the proper usage, dosage, and compatibility with other additives or chemicals used in the oil field.
