Abstract
The present invention relates to improved methods of forming spaced fractures in a subterranean zone penetrated by a horizontal well bore. The methods include the steps of placing an open ended solid liner in the horizontal well bore, pumping a fracturing fluid through the open end of the liner to create fractures in the zone adjacent to the open end, forming perforations in the liner at a selected position spaced from the previously created fractures and pumping a fracturing fluid through the perforations to create additional fractures in the zone.
