Abstract

Well testing of either exploration or production wells is carried out by locating a hollow member, which contains test instruments, in the well bore or within the internal bore of a drill string run, in such a manner that fluid flow up the bore is caused to take place along the path, at least a por­ tion of which includes testing through the region within the hollow member where fluid is in direct communication with the test instruments and performing the well tests while per­ mitting such flow through the member to occur or while pre­ venting fluid escape from the member.
In the method of the invention well testing apparatus may be used for down-hole shut-in purposes even on pro­ duction wells not provided with built-in shut-in facilities.
