ABSTRACT:
Method for recognizing one or more properties of a geological formation by the injection of a fluid into at least one borehole within the formation. The injection fluid either has a different resistivity to the formation and/or formation fluids or has the capacity to change the resistivity of the formation and/or formation fluids. Resistivity mapping is undertaken to determine the distribution of the injected fluid and to therefore understand the permeability structure and fluid distribution of the formation. In addition the injected fluid or mixture of injected and formation fluids can be ignited. By making consecutive resistivity mapping of the formation at selected time intervals during injection, the flow path of injected fluid can be determined by using the collected time lapse resistivity data.
