摘要

method for recovering a formation fluid from an underground geological formation adjacent to the wall of a perforated hole, and method for recovering a forming fluid from a formation adjacent to a wall of a perforated hole. It is a method of recovering a forming fluid from a formation adjacent a wall of a perforated bore, wherein the method includes an estimate of at least one of a formation permeability and a viscosity of the forming fluid. formation. A first tool is selected based on the estimate, and the first tool is selected from a heating and sampling tool, an injection and sampling tool, and a witnessing tool. An attempt is then made to retrieve a formation fluid sample using the first tool and a formation fluid sample is recovered from the formation. A second recovery process may then be initiated, and the second recovery process includes increased mobility of the formation fluid.
