  • Method for controlling fluid-loss and fracturing high permeability subterranean formations
    Patent number: 5558161
    Abstract: A method of fracturing high permeability formations is provided utilizing a first crosslinked gel fluid to initiate the fracture followed by a second gel which results in improved proppant transport and packing of the fracture.
    Type: Grant

  • Method for controlling sand production of relatively unconsolidated formations
    Patent number: 5386875
    Abstract: An improved method for fracturing oil wells is disclosed and claimed herein. In particular, the present invention involves the determination of the direction of fracture propagation, i.e., perpendicular to the minimum stress existing within a given formation and the alignment of perforations produced by a variety of perforating devices with the previously determined direction of fracture propagation. The methods disclosed and claimed herein will eliminate many problems encountered in the prior art, including reducing the pressure required to initiate fractures and reducing the undesirable effects of near wellbore tortuosity. A solidified compound may be placed proximate the fractures to further limit undesirable sand production.
