  • Determining in-situ rock stress
    Patent number: 11143578
    Abstract: A method for determining rock properties includes running a downhole tool into a wellbore formed from a terranean surface to a subterranean zone that includes an underground rock formation, the downhole tool including one or more protrusions coupled with at least one expandable member of the downhole tool, the one or more protrusions including memory metal; actuating the downhole tool, at a location in the wellbore adjacent the underground rock formation, to adjust the at least one expandable member to move the one or more protrusions into or near contact with the underground rock formation; activating the one or more protrusions to fracture the underground rock formation through forcible contact between the one or more protrusions and the underground rock formation; determining a wellbore pressure increase at the location in the wellbore based on the fracture; and determining one or more properties of the underground rock formation based at least in part on the determined wellbore pressure increase.
    Type: Grant
