Abstract:
Packers may be inflated within the wellbore to engage and isolate a portion of the wellbore wall. Charges included within the packers may then be fired to perforate the formation. According to certain embodiments, the charges may be located within drains in the packers that can be subsequently employed to sample the surrounding formation.
