Abstract
A method for forming lateral boreholes from an existing wellbore is provided. The method comprises providing a downhole tool assembly having a whipstock with a curved face. The whipstock is run into the wellbore in a collapsed position. A force is applied to the assembly to cause the whipstock to rotate into an operating position. In this position, the curved face of the whipstock forms a bend-radius that allows a jetting hose to bend across the entire inner diameter of the production casing. A jetting hose is run into the wellbore and along the curved face of the whipstock. The jetting hose is then directed through a window in the production casing. Hydraulic fluid is injected through the hose to create a lateral borehole extending many feet outwardly into a subsurface formation. A downhole jetting assembly for forming lateral boreholes is also provided.
