Introduction
Fracking (short for hydraulic fracturing) extracts oil and gas deposits from rock formations deep beneath the earth. The technique involves injecting a high-pressure solution of water, sand, and chemicals into the ground to create cracks in rock formations through which oil or gas can flow more freely. Guar gum is a natural polymer compound made from guar beans and one of the key ingredients in this fracking fluid.
What is Guar Gum?
Guar gum – a hydrocolloid derived from the seeds of the guar plant Cyamopsis Tetragonoloba. This molecule serves different purposes in various sectors, such as food packaging, cosmetics and medicine. Still, one of its most well-known uses is arguably within the hydraulic fracturing industry. Guar gum is largely used in fracking to increase the viscosity of hydraulic fracturing fluids so that they can suspend proppant (usually sand) during injection into hydraulically fractured rock.
How Guar Gum Functions in the Process of Fracking Fluid
1. Viscosity Enhancement:
Guar gum is added to liquids used in hydraulic fracturing or fracking solely because of their viscosity. Since it is a higher-viscosity fluid, it can suspend and carry a proportionately greater amount of proppant into the fractures. These props open the fractures, enabling oil and gas to flow through the rock formation.
2. Fluid Stability:
Guar Gum helps stabilize the fracking fluid ensuring a consistent fluid volume in high-pressure environments such as during fracking.
3. Reduction of Fluid Loss:
Guar gum, when mixed with water, forms a gel very useful in reducing fluid loss into surrounding rock formations. Loss of too much fluid can drop the pressure in fractures (injection pressure) and can result in a less effective process.
4. Temperature Resistance:
Fracking is often performed at different depths with varying temperatures. Although it is high-temperature stable, Guar gum remains intact during fracking, so changes will keep this fluid active throughout the process.
Benefits of Deploying Guar Gum for Hydraulic Fracturing
1. Natural and Bio-Degradable
Guar gum powder is biodegradable and non-making fracking operations greener.
2. Cost-Effective:
This makes guar gum cheap and widely available, particularly in countries like India and Pakistan that produce it en masse. It extends cost-saving services suitable for oil and gas companies to mix with their fracking fluid formulations.
3. Proppant Suspension Efficiency:
Guar gum can effectively suspend proppants, enabling higher production rates of oil or gas.
4. Versatile Application:
Guar Gum can be customized for various fracking from shallow to deep.
Environmental impact
guar gum plant, with customizable properties, will likely continue to be one the critical ingredients in fracking fluids for years to come.
Conclusion
Hydraulic fracturing relies heavily on guar gum, which increases the viscosity of fracking fluids and improves their stability and efficiency. Its organic, biodegradable properties and low cost make it unique and important in the oil and gas market. Guar gum plays an essential role in modern fracking operations and will remain vital as new advances aim for maximum efficacy and sustainability in oil and gas extraction.
