What is Guar Gum, and How Does it Work in Fracking?
Guar gum is a natural polysaccharide that occurs as guar beans grow (Cyamopsis tetragonoloba). In fracking, guar is used to increase the viscosity of the fracking fluid so that it can transport proppants (usually sand) into rock formations. These proppants keep the fractures open so oil and gas can flow better through them.
Amount of Guar Gum Use on Fracking
The quantity of guar gum powder used in fracking may vary depending on factors such as the demand of a specific drilling operation and the features of the drilled well. Guar gum typically makes up 0.3%–0.6% of the weight in fracking fluid, meaning that for every 1,000 gallons of hydraulic fracturing fluid, an estimated 25 to 50 pounds of guar gum are needed.
As a frame of reference, consider that one frack alone can take anywhere from 2 to 10 million gallons. This, in turn, indicates that for a single well, these quantities of guar gum, based on this volume, can range from 50,000 to 500,000 pounds. The exact number can vary due to the complexities of individual wells and rock formations, but that is more or less how much you would need in order to frack a well(site) properly.
Factors That Governs the Use of Guar Gum in Fracking
1. Formation Properties and Well Depth:
Deeper wells or more difficult rock formations may require higher guar gum concentrations to ensure effective delivery of proppants in switching fluid and pressure maintenance throughout the transient step.
2. Design of fracture along with the proppant requirement
The fracture design, variety, and friability of the proppant used are also effective in determining an estimate of how much guar gum is needed. Couplings of larger or more complex fractures may necessitate increased guar gum for the suspension and transport of proppant.
3. Fluid Viscosity Needs:
Not all fracking operations use fluids with the same viscosity, and many like to boost their thickness. Dewatering work needs a lot of guar gum in fracturing process to fracture the rock effectively and carry proppants. It uses high-viscosity fluids so that more additives will be used.
The Economic Effect of Guar Gum in Fracking
Fracking, in particular, is one area where guar gum accounts for a substantial proportion of production costs. Guar gum prices can skyrocket when utilized during high-demand seasons, significantly impacting its use in oil and gas production applications, especially when the cost of other naturally produced resources such as Oil & Gas are ripe. This resulted in the emergence of other gelling agents and synthetic polymers. However, guar gum remains the best option because it works well at a low percentage (gum by weight), is biodegradable, and costs less under stable market conditions.
Significant role in the energy sector
Discussing guar gum consumption dynamics and how economic effects stretch across markets reveals a comprehensive knowledge of its role in the energy sector. Just as the fracking industry will likely evolve over time with environmental and technological changes, so too may guar gum, but its basic value is still undeniable.
Conclusion
In conclusion, guar gum plays an indispensable role in the fracking process, serving as a key component in enhancing fluid viscosity to effectively transport proppants into rock formations. Its ability to maintain fractures open and facilitate the flow of oil and gas underscores its significance in energy production. While the exact amount of guar gum used in fracking can vary depending on factors such as well depth, formation properties, and fluid viscosity needs, its economic impact is undeniable. Despite fluctuations in guar gum prices and the exploration of alternative gelling agents, guar gum remains a preferred choice due to its effectiveness, biodegradability, and cost-efficiency under stable market conditions. As the energy sector continues to evolve, the role of guar gum in fracking is likely to persist, highlighting its fundamental importance in the industry.
