摘要：The present invention provides an apparatus and method for testing a wellbore,and to an apparatus and method to efficiently and effectively test the annular seal of atubular string positioned within a wellbore. More specifically, the cement seal between a
casing string and a wellbore is tested to assure there is no contamination of groundwateror between different geologic formations. An additional aspect of the present inventionis to provide a testing assembly comprising a frangible body and a tool body, the toolbody providing a passageway to the annular seal when the frangible body is drilled out.In one particular embodiment, the frangible body initially forms an encapsulated borethat aligns with the passageway.
