Abstract
Systems and methods presented herein include an assembly of tools that can be arranged in a wellbore in such a way that allows a combination of formation testing (e.g., with a modular formation dynamics testing tool, a wireline formation testing tool, and so forth) and drill stem testing (DST). The assembly of tools enables performance of both types of activities potentially in a single run in the hole, and facilitate full control of the reservoir and formation fluids or, in case of injection, of injected fluids inside the tubing or drill pipe. In addition, the assembly of tools allows for multiple set points to perform zonal evaluations with the formation testing tools, and facilitate performance of full scale flow tests with the DST string.
