Abstract
The invention being designed in this application relates to a radial drilling method. Boreholes are placed into oil and gas formations to provide openings for the removal of the product. Oil and gas wells extend to different depths and downhole well conditions. The radial system has been designed to accommodate the well conditions and to jet or drill different oil and gas formation. The radial system provides a mill/bit which is rotated from a downhole motor or a surface swivel. The mill ports, the steel casing, and the bit extend outward into the formation forming a borehole to a predetermined length. The borehole is provided without an entrance radius into the formation. Several radial holes can be provided considering a one trip event.
Claims9
A drilling system to produce lateral boreholes comprising:
- a downhole tool sized to accommodate standard oil and gas casing, wherein the lateral boreholes are formed by a cutting arrangement which allows the casing to be parted employing surface of a cutting tool to be compatible with steel or metallic material forming an opening;
- a jetting system allows the boreholes to be formed by high-pressure jet actions into formation, wherein the cutting arrangement also assists the jetting nozzle to form the lateral boreholes into the formation;
- an extension tube and cutting nozzle arrangement is rotated from the surface or a downhole motor allowing variable speeds to be provided for parting the casing and drilling of the lateral boreholes, wherein the extension tube is constructed of a memory material allowing the extension tube to be bend around a drive wheel and rotated and maintaining an original shape of the extension tube once drilling load is removed.
