Corrosion tester tool for use during drill stem test

Abstract

In accordance with embodiments of the present disclosure, systems and methods for gathering corrosion data during a drill stem test (DST) performed in a wellbore extending through a subterranean formation are provided. Such systems include a specialized tool that may be run into the wellbore on a DST tubular string to perform corrosion measurements during the DST. This corrosion tester tool (CTT) may include a number of material coupons disposed therein for exposure to formation fluids routed through the CTT and the DST tubular string. The CTT may hold material coupons of several different materials that could potentially be used to form production tubing or other production equipment needed for well completion operations. After the different material coupons are exposed to the formation fluid via the CTT, the material coupons may be inspected to determine which material should be used to form the production tubing/equipment for that particular well.
