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.
