Drilling apparatus and system for drilling wells

A method of drilling a well with a motor having a power shaft, the method comprising:

• providing a drilling apparatus, said drilling apparatus comprising:
• a driver operatively connected to the power shaft, said driver having a body, containing a plurality of cogs;
• a first bit having a first end, and wherein said first end is connected to said driver so that rotational movement of said driver is imparted to the first bit;
• a sleeve disposed about a portion of said power shaft, said sleeve having a plurality of openings therein for placement of a plurality of pinions, said pinions having a pin disposed there through, and wherein said sleeve has a radial shoulder for attaching said plurality of pins;
• a housing having, a second bit formed thereon, and wherein said housing has an internal portion that contains a plurality of internal cogs engaging said pinions;
• providing a casing string concentrically placed within the well, said casing string being operatively connected to said sleeve;
• rotating the power shaft via a fluid flow down an internal portion of the casing string and the drilling apparatus;
• rotating the first bit in a first direction;
• drilling the well with the first bit;
• rotating the cogs on said driver;
• engaging the pinions with the cogs on the driver;
• engaging the internal cogs on the housing;
• rotating the housing in a counter direction relative to the first bit;
• rotating the second bit in the counter direction;
• drilling the well with the second bit.

A device for boring a well, the device being attached to a motor and wherein the motor has a power shaft for imparting rotational movement, the device comprising:

• a driver mandrel operatively connected to the power shaft, said driver mandrel containing a cylindrical body;
• a first bit member having a first end and a second end, and wherein said first end is connected to said driver mandrel so that rotational movement of said driver mandrel is imparted to the first bit member, and wherein the first bit member has an inner bore, and wherein said second end has a first bit;
• a sleeve disposed about a portion of said power shaft, and wherein said sleeve has a radial shoulder;
• a casing string attached to said sleeve, and wherein said casing string is designed to be permanently placed within the well once the boring is completed, and wherein an inner bore of the casing string is in fluid communication with the inner bore of the first bit;
• a housing disposed about said driver mandrel;
• a second bit member attached to the housing;
• a planetary gear anchored to said radial shoulder and disposed between said driver mandrel and said housing, and wherein said planetary gear is adapted for imparting rotation from said driver mandrel to said housing in a counter radial direction.
