Abstract:
Some examples of monitoring hydrocarbon reservoirs using induced polarization effect includes inducing polarization in a subterranean zone using an induced polarization fluid. The subterranean zone includes first formations and second formations. A quantity of hydrocarbons in the first formations is greater than quantity of hydrocarbons in the second formations. The induced polarization data is obtained from the subterranean zone. A portion of the induced polarization data from the first formations is different from a portion of the induced polarization data from the second formations. The second formations in the subterranean zone are identified based on the obtained induced polarization data

Claim (Index 1):
A system comprising:\n processing circuitry configured to perform operations comprising:\n obtaining induced polarization data from a subterranean zone, the subterranean zone comprising first formations and second formations, a quantity of hydrocarbons in the first formations greater than a quantity of hydrocarbons in the second formations, the induced polarization data induced in the subterranean zone using an induced polarization fluid, a portion of the induced polarization data from the first formations being different from a portion of the induced polarization data from the second formations; \n identifying the second formations in the subterranean zone based on the obtained induced polarization data by determining volume distribution of electrical resistivity and chargeability in the subterranean zone from the induced polarization data; \n monitoring changes to the electrical resistivity and chargeability in the subterranean zone, wherein changes to electrical resistivity and chargeability in the first formations are different from changes to electrical resistivity and chargeability in the second formations that have absorbed the induced polarization; and \n correlating the changes to the electrical resistivity and chargeability to rock formations in the subterranean zone, wherein correlating comprises differentiating between first formations and second formations based on differences between the changes to the electrical resistivity and chargeability in the first formations and the changes to the electrical resistivity and chargeability in the second formations that have absorbed the induced polarization fluid.
