Abstract: A method for mapping inter-well porosity includes injecting a Type 1 tracer into a hydrocarbon-bearing reservoir via an injector well, wherein the Type 1 tracer is a passive tracer, injecting a Type 2 tracer into the hydrocarbon-bearing reservoir via the injector well, wherein the Type 2 tracer is a porosity-sensitive tracer, detecting a breakthrough of the Type 1 tracer and a breakthrough of the Type 2 tracer in produced fluid at a producer well, and comparing the breakthrough of the Type 1 tracer with the breakthrough of the Type 2 tracer to provide a map of inter-well porosity.

Abstract: Methods and systems for determining electrical characteristics of a subsurface formation are disclosed. The method may include installing a first electrically insulating spacer between well liners in the well to form an on-demand electromagnetic source electrode and installing a second electrically insulating spacer between well liners in the well to form an on-demand electromagnetic receiver electrode. The method may further include performing an electrical survey using the on-demand electromagnetic source and receiver electrodes, determining a map of the at least one electrical characteristic in a subsurface region surrounding on-demand electromagnetic source and receiver electrodes based on the electrical survey, determining a map of at least one formation property based on the map of the electrical characteristic, and updating a hydrocarbon reservoir production plan based on the map of at least one formation property.

Abstract: A method for monitoring waterfront movement in a subsurface formation involves performing forward modeling of at least one deep electromagnetic survey of the waterfront movement, and determining locations for installing an electrically insulating spacer between well liners to form an on-demand electromagnetic source electrode. Based on the forward modeling, repeat survey time intervals are predicted. The method involves, during well completion, installing the electrically insulating spacer between the well liners in a reservoir to form at least one on-demand electromagnetic source electrode, and installing the electrically insulating spacer between the plurality of well liners in a reservoir to form an on-demand electromagnetic receiver electrode. A waterfront survey is performed by conveying a production logging tool into a well that temporarily converts the well liners into an on-demand electromagnetic source electrode and an on-demand receiver electrode, and inverse modeling of the waterfront survey is performed to produce a water saturation image.
