Synthesis Of Sodiumcarboxymethylguar Using Chloroacetic Acid For Hydrofracking Technology

Abstract

As the demand of fossil fuel and other energy sources is increasing day by day with a gradual decrease in their levels, the attention is now shifted towards the shale gas exploration and production. The method and the procedure is described for the synthesis of Guar gum derivative used in Hydraulic Fracturing Technique (HFT) which is used in Oil and Natural Gas Production. The technique is routinely used in the oil and gas industry to improve or stimulate the recovery of hydrocarbons from underground formations. HFT is typically employed to stimulate wells which produce from low permeability underground formations. Guar gum is a natural polymer with a high viscosity and used as a thickener in number of fields which includes textile, paint, food and others. It is found that the viscosity of Guar gum powder can be gradually increased with the substitution of hydroxyl groups in its structure. The derivative prepared is used in simulating those wells for effectively increasing the production of oil and gas, most importantly Shale gas. The derivative was prepared and the yield was compared with the standard Guar gum sample and waSs found to be in agreement with the literature.
