| 246 | Method of fracturing while drilling | US13706902 | 2012-12-06 | US08973661B2 | 2015-03-10 | Shaohua Zhou |
| A method of fracturing a formation that at the same time drills a wellbore through the formation selectively deploys a seal from a drill string and pressurizes the wellbore beneath the seal. The seal can be formed by moving sliding blades into channels between cutting blades on a drill bit. The seal can also be a packer on the drill bit that selectively expands radially outward into sealing engagement with the wellbore. At a designated depth in the wellbore, the seal is deployed and fluid is diverted into the space. A pressurizing system pressurizes the fluid so that pressure in the space overcomes the formation strength and fractures the formation adjacent the enclosed space. The packer can be released, drilling can resume, and fracturing can occur at a different depth in the wellbore. | ||||||
