1. A method, comprising:
obtaining, using a plurality of sponge coring tools, acquired sponge core data from a plurality of wells in a plurality of formations, wherein at least one sponge coring tool among the plurality of sponge coring tools comprises a core barrel and a sponge sleeve that is made of a polyurethane sponge;
obtaining, using a dielectric logging tool, dielectric log data regarding a geological region of interest wherein the dielectric logging tool comprises an antenna, at least one transmitter configured to transmit an electromagnetic field, and at least one receiver configured to measure a phase and an amplitude of the electromagnetic field;
obtaining, by a computer processor, a rock type for the geological region of interest, a reservoir zone type for the geological region of interest, and a porosity value for the geological region of interest using one or more well logs;
generating, by the computer processor, predicted sponge core data of the geological region of interest using a neural network model, the rock type, the reservoir zone type, the porosity value, and the dielectric log data,
wherein the rock type, the reservoir zone type, the porosity value, and the dielectric log data are data inputs to the neural network model,
wherein the predicted sponge core data comprises an oil saturation value that describes an amount of oil found in a core sample acquired during a coring operation in the geological region of interest, and
wherein the neural network model is trained using a plurality of dielectric logs the acquired sponge core data, and a backpropagation algorithm; and

determining, by the computer processor and using the predicted sponge core data, an amount of hydrocarbons in the geological region of interest.
