Every small change in pH of fracturing fluid matters during hydraulic fracturing. Are your fluids optimized for peak performance? Buffering agents are critical chemical solutions that help stabilize pH. They prevent drastic changes in acidity or alkalinity within your fluids. 

Sunita Hydrocolloids Inc. USA is your reliable partner for high performance buffering agent. We offer buffering agents that meet a variety of needs for both cementing and fracturing applications. Buffers with sodium and potassium cations are offered in conjunction with hydroxide, oxide and carbonate anions or mixtures of these anions. Sunita buffering agents are offered at various concentrations to meet application needs at both low and high temperatures.

What is a buffering agent? 

Buffering agents are chemical additives designed to stabilize the pH of fluids used in drilling, fracturing and acidizing treatments. Without them, fluid chemistry can swing unpredictably, leading to inconsistent performance and costly setbacks. They keep the pH of your fluid system within a controlled range for optimal oilfield operations.

The Critical Role of Buffering in Well Stimulation

Buffering agents handle uncontrolled pH swings that can significantly impact your operations.

Why pH Balance Makes or Breaks Your Operation

Precise pH control in fracking is non-negotiable as it is fundamental to how buffering works. Crosslinker activation relies heavily on specific pH ranges; thus, incorrect pH impacts crosslinkers’ performance. Gel polymers, crucial for fluid viscosity, are also pH sensitive. Also, proppant transport efficiency directly depends on stable fluid properties. Maintaining pH balance via buffering agents ensures optimal fluid chemistry.

Consequences of Poor pH Management

Poor pH control in fracking leads to significant issues such as reduced viscosity and premature gel breaking. This compromises fracture effectiveness. Uncontrolled pH also causes increased corrosion rates on equipment, resulting in significant repair and replacement costs. Not using pH buffers can cause inconsistent fracture propagation, which leads to less effective stimulation. Ultimately, poor pH management can result in reduced hydrocarbon recovery. Our buffering agents prevent these costly problems.

Precision Applications of Buffering Agents Across Operations

Optimizing Hydraulic Fracturing Fluids

pH Buffering offers precise control across various oilfield operations. Our buffering agents are essential for maximizing fracturing fluid performance:

• Crosslinked Gels: Crosslinked fluids require a pH adjustment as the rate and extent of crosslinking are significantly influenced by pH. Buffering agents guarantee proper crosslinker activation and viscosity development.
• Hybrid Fluid Designs: pH adjustment is necessary for the crosslinked portion of the hybrid fluids to ensure proper gel formation, while slickwater components typically do not require pH control.
• Additional benefits: pH control helps prevent precipitation of minerals such as iron, maintains fluid stability and protects equipment. In this way, buffering agents help maintain stability and efficiency across complex fluid blends

Enhancing Acid Stimulation Treatments

In acidizing, precise pH management is equally vital in:

• Preventing Premature Acid Spending: Our buffering agents help acid maintain strength to reach the target zone effectively.
• Improving Zonal Coverage: Consistent acid activity leads to more uniform stimulation. This results in better hydrocarbon recovery.

Sunita USA’s Buffering Agents: Engineered for Peak Performance

At Sunita USA, we engineer buffering agents that represent the forefront of oilfield pH stabilizers. Our cutting edge formulations deliver the stability needed for peak performance in challenging drilling and completion scenarios.

Sunita offers a 4-5% solution of potassium hydroxide for crosslinking guar at lower temperatures. This buffer is optimized to adjust the pH to about 9 – 12. Loadings of the buffer can be adjusted to meet the desired requirements of the fluid.

For moderate to higher temperatures, Sunita offers a buffer that combines potassium hydroxide and potassium carbonate in an optimized ratio to achieve superior crosslinked viscosity and stability. The loadings of the buffer can be adjusted to achieve the desired pH and maintain fluid stability within the pH range of 9 – 12.

Advanced Chemistry for Demanding Conditions

• Extreme Thermal Stability: Our high-temperature buffers remain fully effective up to 350°F (177°C). This ensures your fluids maintain their integrity deep underground.
• Broad pH Management: We offer precise pH control from 3.5 to 11. This adaptability supports diverse fluid designs and operational requirements.
• Resistant to Salinity: Our buffering agents are robustly salt tolerant. They perform consistently even in high total dissolved solids (TDS) environments, critical for recycled and produced waters.

Tangible Field Benefits You Can Measure with Performance Advantage

Implementing Sunita USA’s buffering agents leads to direct operational gains:

• Enhanced Fluid Performance: Achieve a measurable 20-30% improvement in fluid stability. This translates to better proppant transport and more effective fracture geometry.
• Asset Protection: Reduce corrosion rates on costly equipment. This extends the lifespan of your pumping units, downhole components, and production strings.
• Optimized Chemical Use: By maintaining ideal pH, our solutions ensure other fluid additives function at their best. This reduces the need for re-treating or over-treating, cutting down on overall chemical consumption and lowering operational expenses
