Abstract (en)
An intelligent down hole testing system for conducting well testing has down hole flow. The system includes an apparatus for use in a wellbore having an annulus (10), the apparatus comprising a work string (20) placed in the annulus (10), a sensor (36) in said work string (20) and a control valve (40) in said work string (20), wherein said control valve (40) operates in response to reservoir measurements from said sensor (36). The system allows for flow and shut-in testing and fluid sampling down hole without the need for surface monitoring or control. <IMAGE>
