2026317 9008878 PCTABS00001 A fluid flow measuring or so-called production logging instrument (24) for fluids produced in a well includes an inflatable packer (38) for forming a seal (40) in the wellbore (10) to require diversion of wellbore fluid through a passage formed in the instrument whereby fluid flow rate and other fluid properties may be measured. The inflatable packer (38) receives pressure fluid from the tubing string (22) and may be remotely controlled to inflate and deflate, at will, through signals conducted from the surface to the instrument by way of a cable (30) extending through the tubing string. The instrument (24) includes a main wellbore fluid flow passage in which a shutoff valve (92) is disposed for controlling the flow of fluid through the passage and which may be automatically closed or opened in response to actuation of the packer seal (40).
