ADDITIVE TO HYDRAULIC FRACTURING FLUID AND METHOD OF USING THE SAME

摘要

This invention is used in hydraulic fracturing of subterranean formations and is more particularly a method to minimize the proppant settling rate. Prevention of proppant settling and proppant slug settling and assistance in proppant transport are achieved if the size at least in one of dimensions of the new additive should be comparable with the fracture width. During fracturing treatment proppant are suspended in a fracturing fluid for several hours, so proppant settling is an important issue.
