<p>A method and apparatus for identifying a ballooning zone in downhole formations. In one embodiment, a method for identifying a ballooning zone in downhlole formations includes disposing a drill string in a wellbore. The drill string includes a plurality of wired drill pipes connected end-to-end, and a bottomhole assembly connected to the drill pipes. While circulating drilling fluid through the wellbore, a first resistivity of a formation drilled is measured. While not circulating drilling fluid through the wellbore, a second resistivity of the formation drilled is measured. The first resistivity and the second resistivity are compared. Based on a result of the comparing, a level of ballooning attributable to the formations is identified.</p> |
