The product is obtained using the method given above. The method of processing an underground layer drilled by a well shaft involves formation of processing fluid which contains an aqueous liquid and powder of guar gum containing at least 70 wt % resin material and at least 15 wt % hull material at feeding the processing fluid into the underground layer through the well shaft. The invention is developed in subclaims.;EFFECT: more efficient production of guar gum and use thereof.;24 cl, 6 dwg
