Inverted drainholes and the method for producing from inverted drainholes

1. A method for producing products from a subterranean reservoir from an existing generally vertical wellbore, the method comprising the steps of:

lowering, positioning and securing a reverse whipstock in said wellbore;

securing a tube from the surface to a pull tube which extends above, through and below the reverse whipstock;

pumping fluid from the surface through said tube from the surface and through a U-tube device below said pull tube and said reverse whipstock;

drilling at least one inverted drainhole with a drill mechanism using force from said pumping fluid, wherein the drilling direction for the drainhole is less than 90 degrees from vertical

pulling said pull tube upward vertically toward the surface while pumping said fluid;

completing the wellbore and said inverted drainhole to form a producing flow path to allow fluids and solids to flow by gravity from the subterranean reservoir into the wellbore;

lowering said pull tube in order to lower said drill mechanism out of said inverted drainhole to permit removal from said wellbores; and

allowing said fluids and solids to flow or be pumped to the earth's surface up the wellbore.

2. The method as set forth in claim 1 including holding said reverse whipstock in the wellbore with an anchor device affixed to a well casing.

3. The method as set forth in claim 1 including holding said reverse whipstock in the well bore utilizing tubes or pipes from the surface to said reverse whipstock.

4. The method as set forth in claim 1 including multiple of the at least one inverted drainholes created out of the vertical well bore.

5. The method as set forth in claim 1 wherein said step of pumping fluid from the surface includes fluid chosen from a group consisting of gas, liquid and super critical fluids.

6. The method as set forth in claim 1 wherein said step of drilling at least one inverted drainhole is chosen from the group consisting of waterjetting, abrasive water jetting, abrasive slurry jetting, FLASH ASJ cutting and drilling, and cavitation, laser, or plasma methods.

7. An apparatus for creating inverted lateral drainholes which comprises:

a first tube extending downhole from a surface;

a reverse whipstock, wherein said first tube extends through said reverse whipstock;

a U-tube device having a first end connected to and in fluid communication with said first tube;

a second tube connected to and in fluid communication with an opposed end of said U-tube;

a drill mechanism powered by force from pumping fluid through said first tube, through said U-tube, and through said second tube; and

means for raise and lower said drill mechanism from the surface.

8. A method for producing products from a subterranean reservoir from an existing wellbore, the method comprising the steps of:

lowering, positioning and securing a reverse whipstock in-said wellbore;

securing a tube from the surface to a pull tube which extends above, through and below the reverse whipstock;

pumping fluid from the surface through said tube from the surface and through a U-tube device below said pull tube and said reverse whipstock;

drilling at least one inverted drainhole with a drill mechanism using force from said pumping fluid, wherein the drilling direction for the drainhole is less than 90 degrees from said existing wellbore;

pulling said pull tube upward vertically toward the surface while pumping fluid;

completing the wellbore and said inverted drainhole to form a producing flow path to allow fluids and solids to flow by gravity from the subterranean reservoir into the wellbore;

lowering said pull tube in order to lower said drill mechanism out of said inverted drainhole to permit removal from said wellbores; and

allowing said fluids and solids to flow or be pumped to the earth's surface up the wellbore.
