Comparative study of guar beans polymeric compositions and carboxymethyl cellulose as gelling systems for conducting hydraulic fracturing of a formation
The article discusses the results of comparative studies of polymeric compositions on the basis of the guar beans and carboxymethyl cellulose. According to the results of studies of technological characteristics of solutions comparable formulations it is determined that both compounds have similar characteristics but differ in their cost and availability. Domestic agent is more readily available and less expensive than the imported one. The critical concentration of the domestic composition is a bit higher than that of a foreign one, so a higher concentration is required to obtain the reliable intermolecular bonds. Besides, during destruction of gel based on carboxymethyl cellulose there aren’t formed insoluble sediments, while such sediments are present in gel based on guar. However, conductivity recovery of proppant members for both reagents is approximately the same, that means that the home agent is a good analogue to replace the foreign one and can used by home service companies.
