Product Information Sheet

WGA-15 is manufactured by Sunita Hydrocolloids Private Limited, a joint venture company of Weatherford International Ltd., USA.

WGA-15 is a natural galactomannan polysaccharide obtained from ground

endosperm of the legume Cyamopsis tetragonolobus, an annual plant which grows mainly in arid and semi-arid regions of India.

WGA-15 is fast hydrating guar gum to be used in various oil field applications especially in hydraulic fracturing as carrier for proppant.

WGA-15 compared to the other viscosifiers could be cross-linked successfully

using a metal ion based cross-linking agent. Up on cross linking the resultant fluid can handle high concentrations of proppant and provides increased fracture width

and penetration.

WGA-15 is compatible to other additives being added in oil field applications.
