ABSTRACT:
A shock mounted recorder carrier for a drill stem testing string, adapted for placement in a borehole, includes offset inner and outer bodies for placement of recorders within the carrier and further includes an overpressure gauge protector for protecting a set of recording gauges disposed in the carrier from a well fluid pressure which is greater than a predetermined amount above annulus fluid pressure and a balance joint for providing an oppositely directed force on the recording gauges relative to a direction of flow of the well fluid within the carrier thereby preventing the well fluid pressure from "bottoming out" the shock mount on which the recording gauges are mounted.
