Stimulation through fracturing while drilling

A method for preparing a formation surrounding a wellbore to bear hydrocarbons through a borehole, the method comprising steps of:

• inserting a bottomhole assembly into the borehole;
• drilling the formation with the bottomhole assembly;
• characterizing the formation with logging tools on the bottomhole assembly, wherein the logging tools create first information;
• placing one or more fractures in the formation using the first information without removal of the bottomhole assembly from the wellbore;
• further drilling the formation with the bottomhole assembly after the immediately preceding placing step;
• further characterizing the formation with logging tools on the bottomhole assembly to create second information;
• placing another fracture with feedback from the second information;
• and
• repeating the further drilling, further characterizing and placing steps as necessary during the method.

A method for preparing a formation surrounding a wellbore to bear hydrocarbons, the method comprising steps of:

• drilling the wellbore with a bottomhole assembly;
• increasing a pressure of a fluid in at least a section of the wellbore while the bottomhole assembly is in the wellbore;
• fracturing the formation appurtenant to the wellbore to create one or more fractures;
• analyzing the one or more fractures;
• propping the fracture with sealant;
• performing further fracturing to create another fracture based upon the analyzing step;
• and
• drilling the wellbore with the bottomhole assembly, wherein the steps listed between the two drilling steps occur in time between the two drilling steps without pulling the bottomhole assembly out of the wellbore.

A method for preparing a formation surrounding a wellbore to bear hydrocarbons, the method comprising steps of:

• drilling the wellbore with a bottomhole assembly;
• increasing a pressure of a fluid in at least a section of the wellbore while the bottomhole assembly is in the wellbore, wherein the section is pressure isolated from another section of the wellbore;
• perforating the formation;
• fracturing the formation appurtenant to the wellbore and proximate to the perforations to create one or more fractures, wherein locations for applying fracturing are controlled with feedback information gathered in the borehole from one or more sensors;
• analyzing the one or more fractures with information from the one or more sensors;
• propping the fracture with a sealant;
• performing further fracturing to create another fracture based upon the analyzing step;
• casing the wellbore, and drilling the wellbore with the bottomhole assembly, wherein the steps listed between the two drilling steps occur in time between the two drilling steps without pulling the bottomhole assembly of the wellbore.
