During the exploration and appraisal phases field data is collected for the determination of reservoir parameters which will govern the Field Development and production strategy. Permeability-thickness, hydrocarbon properties and reservoir extent are critical parameters acquired during this phase which are used to evaluate expected well and reservoir performance. Dynamic Flow tests, combined with Downhole Fluid Analysis and fluid samples are commonly used to obtain this information. The most common flow tests today use either Wireline Formation Testers (WFT) for small scale tests, or Drill Stem Tests (DST) for larger scale flow tests. This paper will describe a workflow in which the information acquired from the small scale WFT tests can be used to optimize the design and execution of the larger, and typically more costly, DST’s. The ultimate goal of the workflow is to increase the value of the information obtained, and the overall success rate of the DST’s performed.
