| Application of Guar Gum for Oil and Gas Industry: A Green Biopolymer |
Guar gum, a natural biopolymer derived from guar seeds, is widely used in the oil and gas industry for its strong thickening and stabilizing properties. Through chemical and physical modifications, guar gum is transformed into carboxymethyl hydroxypropyl guar gum (CMHPG), a fast-hydrating, high-viscosity polymer with excellent thermal stability, electrolyte tolerance, and compatibility with various additives. CMHPG is a revolutionary polymer for hydraulic fracturing, combining carboxymethyl and hydroxypropyl modifications on the guar backbone. It offers exceptional thermal stability, robust performance in brines, reduced formation damage, and versatile cross-linking behaviour, making it ideal for mid-to-high temperature operations. read

To stay ahead in a rapidly evolving world, businesses must move from intention to action. Embracing renewable energy is no longer a choice but a cornerstone of sustainable growth — empowering organizations to drive progress, strengthen resilience, and define the future of responsible enterprise, says Ranjth Nair.
