DETERMINING VISCOSITY OF FLUIDS FROM WELL LOGS USING ELECTROSEISMIC MEASUREMENTS

摘要

The current invention provides methods for determining the viscosity of pore fluids found in subterranean formation. In particular, the current invention provides methods for distinguishing between pay and non-pay zones of subterranean formation on the basis of the viscosity of the pore fluid found within the zones. Through use of well logging techniques, the current invention measures electromagnetic radiation generated by movement of the pore fluid through the formation in response to a Stoneley wave to determine the viscosity of the pore fluid.
