Abstract: A method of hydraulically fracturing a formation comprises controlling a pump rate during hydraulic fracturing of the first section of the horizontal well bore during a first period to break down the formation while reducing pick up of sand positioned in the well bore; during a subsequent second period to pick up the sand positioned in the well bore generally at a rate at which the formation will accept the sand; and, during a subsequent third period to fracture the formation.

Abstract: A method of fracturing a formation with a fracturing fluid wherein the formation has particulate material that swells or migrates upon exposure to the fracturing fluid comprises preparing a fracturing fluid comprising (1) a thickening compound comprising a first surfactant selected from the group consisting of a cationic surfactant having only a single cationic group, an amphoteric surfactant and a mixture thereof; and, an anionic surfactant; and, (2) water, wherein no or essentially no inorganic salt is added to the fracturing fluid; and using the fracturing fluid to fracture the formation. A method for recycling a fracturing fluid is also provided.
