APPLICATION AREAS
Oil Field Scale Inhibitor Applications
Browse our specialised scale inhibition solutions tailored to your specific operational challenge. Select your application below to explore our recommended products.
Downhole Squeeze Treatments
Introduction: Long-term reservoir protection through batch treatment.
Summary: This application involves pumping a scale inhibitor solution directly into the production zone of a well. The chemical is designed to adsorb onto the reservoir rock and then slowly desorb back into the produced fluids over a period of 3 to 18 months, providing continuous protection against scale formation in the critical near- wellbore area and lower tubing.
Scale Problems:
Severe Barium/Strontium Sulphate Scaling: Often the primary target for squeezes due to the irreversibility of these scales.
Calcium Carbonate Scaling: Common in reservoirs where pressure drop leads to CO₂ degassing.
Mixed Scale Regimes: Complex combinations of sulphate and carbonate scales.
Our Products for This Application:
🔹BRITOLY SI 9002

Continuous Injection: Wellhead & Flow lines
Introduction: Continuous protection for production tubing and surface networks.
Summary: This is the most common method for scale control, involving the continuous injection of a scale inhibitor at the wellhead or into flow lines. It is essential for protecting the entire production system—from the top of the downhole tubing to the processing facility—from deposition and blockage.
Scale Problems:
Calcium Carbonate Scale: Frequently forms in the lower-pressure regions of the tubing and at the wellhead due to pressure drop.
Barium Sulphate Scale: Can form throughout the system as produced water becomes oversaturated.
Iron Carbonate/Sulphide Scale: Often related to corrosion products and H₂S presence.
Our Products for This Application:

• High-Temperature Capable: Scale inhibitor component remains effective in hot production fluids
Water Flooding & Enhanced Oil Recovery (EOR)
Introduction: Protecting the reservoir and injection system from incompatible waters.
Summary: When water is injected into a reservoir to maintain pressure or sweep oil (water flooding or EOR), it can mix with the native formation water, creating a high risk of scale. Scale can block the injection well itself, damage the reservoir formation near the wellbore, or block the production well where the fluids mix.
Scale Problems:
Calcium Carbonate Scale: Forms in injection wells due to temperature increase.
Sulphate Scales (BaSO₄, SrSO₄, CaSO₄): Occur when sulphate -rich injection water (e.g., seawater) mixes with formation water rich in barium, strontium, or calcium.
"Squeeze" Scale in Producers: The injected water can cause scale in the production wells, often requiring their own squeeze treatments.
Our Products for This Application:

Subsea & Deepwater Systems
Introduction: Ultra-reliable protection for critical, inaccessible infrastructure.
Summary: Subsea systems have zero tolerance for scale-induced failures due to the immense cost and complexity of intervention. Chemicals must be exceptionally reliable, stable, and compatible with long umbilicals and complex subsea architecture. The focus is on "right-first-time" performance.
Scale Problems:
All Scale Types are Critical: Barium sulphate and calcium carbonate are the most common threats.
Hydrate Inhibition Compatibility: Scale inhibitors must be compatible with thermodynamic hydrate inhibitors (e.g., methanol, MEG), which can alter their performance.
Barite Sag: In drilling completions, weighted drill solids can settle, creating deposits.

Risk Mitigation: Maximizes reliability of inaccessible, capital-intensive equipment.
🔹 BRITOL SI 400 Plus
Surface Facilities & Process Control
Introduction: Safeguarding separation, heating, and treatment equipment.
Summary: As fluids move through the production train on the surface—through separators, heaters, treaters, and export pipelines—changes in temperature, pressure, and composition can trigger scale formation. This can lead to equipment failure, level control issues, and heat transfer inefficiency.
Scale Problems:
Calcium Carbonate Scale: The most common scale in heaters and treaters due to temperature increase.
Sulphide Scales (ZnS, FeS): Often found in separator dump lines and water handling systems.
Naphthenate & Soap Scales: Organic deposits that can be mitigated with specialised chemicals.
