System and method of fracturing while drilling

A system for use in operations in a subterranean wellbore comprising:

• a drill bit depending from a string of tubulars to define a drill string;
• a seal that selectively expands radially outward from the drill string into sealing engagement with an inner surface of the wellbore;
• a drilling nozzle on the bit in selective communication with a source of pressurized drilling fluid;
• and
• a fracturing port on the drill bit in selective communication with a source of pressurized fracturing fluid.

A system for forming and fracturing a subterranean wellbore comprising:

• a drill bit depending from a length of drill pipe to define a drill string;
• a seal that extends radially outward from the drill string into sealing engagement with an inner surface of the wellbore;
• a drilling nozzle on the bit in selective communication with a source of pressurized drilling fluid that is in an open position when the drill bit is drilling the wellbore;
• and
• a fracturing port on the drill bit in selective communication with a source of pressurized fracturing fluid that is in a closed position when the drill bit is drilling the wellbore and is selectively opened when the drill bit is rotationally stationary, so that the pressurized fracturing fluid can flow from the inside the drill bit and into the wellbore and fracture the wellbore.
