ABSTRACT:
A method for forming as by drilling multiple boreholes into a shallow hydrocarbon pay zone from a single central vertical borehole is disclosed. A single large diameter vertical hole is first provided between the pay zone to a depth greater than a predetermined distance.
Using special drilling equipment, one or more directional wells are then drilled starting at locations below the pay zone and proceeding in an upwardly and outwardly direction from the vertical hole. By selecting the predetermined starting depth and angle of direction for the upward and outward drilling phase of the method, great range of horizontal penetration may be obtained with respect to the central borehole thereby facilitating the efficient production of a shallow pay zone from a single drilling platform.
