Abstract
A coring tool includes an electronics section that includes a material that is buoyant in a wellbore fluid, a coring section coupled to the electronics section and including a sidewall coring unit operable to penetrate an inner wall of a wellbore and thereby obtain a core sample, and a stabilizer arm assembly operable to laterally extend a stabilizer arm into engagement with the inner wall of the wellbore. A weight section is operatively coupled to the electronics and coring sections and exhibits a weight that overcomes buoyancy forces generated by the buoyant material in the wellbore fluid, and a release mechanism releasably attaches the weight section to the electronics and coring sections. Activating the release mechanism detaches the weight section, and thereby allows the electronics and coring sections to float in the wellbore fluid and ascend the wellbore.
