  • Method of packing extended reach horizontal wells
    Patent number: 6581688
    Abstract: The present invention provides a method for efficiently packing proppant in an extended reach, horizontal, open hole annulus. For a given set of fixed parameters, such as the wellbore size, screen size and formation fracture pressure, the method provides a combination of critical parameter values, including the proppant density, the mixture ratio of proppant and liquid and the pump rate which will yield an efficient and effective placement of the proppant in the annulus.

  • Method of packing extended reach horizontal wells
    Publication number: 20010047865
    Abstract: The present invention provides a method for efficiently packing proppant in an open hole annulus. The method provides at least one combination of a plurality of parameters which will provide an efficient and safe packing operation for extended reach horizontal open holes. For a given set of fixed parameters, such as the wellbore size, screen size and formation fracture pressure, the method provides a combination of values of critical parameters, including the proppant density, the mix ratio of proppant and liquid and the pump rate which will yield the most efficient and effective placement of the proppant in the annulus.
