METHOD AND APPARATUS FOR FORMATION TESTING AND SAMPLING WHEN PERFORMING SUBTERRANEAN OPERATIONS |
摘要 |
<p>Methods and systems for improving operations of a formation tester are disclosed. The formation tester (400) is placed in a wellbore at a location of interest. The formation tester comprises a first isolation pad (402) coupled to a pad carrier (410) and a second isolation pad (404). The first isolation is extendable to substantially seal a probe of the formation tester against a well bore wall. The first isolation pad is then replaced with the second isolation pad if it is determined that the first isolation pad should be replaced with the second isolation pad.</p> |
