Methods and systems for determining pore-volume of a fracture in a core plug. The method includes developing a grid block model constrained by fracture porosity estimated from a mechanical laboratory test, aperture calculation, and discrete fracture model validation. The method further includes determining the natural fracture porosity and pore volume from the equivalent medium for natural fractures, determining oil or gas reserves by calculating the fracture pore volume, and determining fracture porosity measurement from a test to calibrate 3D fracture models. The method also includes determining fracture porosity from a mechanical test, analyzing borehole image logs, developing a geomechanical model and fracture drivers, performing fracture model predictions, validating and calibrating the model, and determining fracture pore-volume of the core plug.

Methods and systems for determining reservoir and fracture properties

In reservoir hydrocarbon exploration, fracture characteristics of subsurface reservoir formations are analyzed based on measures obtained about the subsurface formations and rock. Models of subsurface reservoirs are developed with predictions of natural fracture networks within the subject subsurface reservoirs. The mechanical properties of the formation rock in the reservoirs serve as a main controller to model the natural fractures distribution and their properties. The models so formed are important in the location and completion of wells for hydrocarbon exploration and production.
