Wellbore perforation method and apparatus

Image Number 4 for United States Patent #6401818.

A method and apparatus is described for increasing hydrocarbon production from a production well by determining a bedding plane (permeability anisotropy) of a hydrocarbon bearing formation and using a perforating tool to form in the formation holes having an essentially elliptical or elongated cross-section with the longest axis of said elliptical or elongated cross-section oriented perpendicular to said bedding plane (or in direction of the lowest permeability).
