Petrophysical properties of oil & gas fields can be determined by analyses of rock cores and plugs using Digital Rock Physics. These data are critical for quantifying, for instance, the volume of accessible oil in a given reservoir, or the cost of its extraction. Non destructive 3D imaging enables to explore the interior of a rock sample, down to the microscopic scale at which flow and transport processes operates and control petrophysical properties. It is then possible to calculate these properties accurately by simulating these processes directly on 3D images thanks to Digital Rock Physics.

The focus of many of the world’s oil fields is now moving to either improved oil recovery from mature fields, or development of new resources, for which conventional methods may not be possible. As projects become larger, more expensive and complex, it is valuable to have a comprehension of the inner rock structure and associated fluids behavior, and how these rock-fluid properties can be used to produce oil from these fields. Understanding where oil is located within a porous medium by 3D imaging helps to target this residual oil. Simulations in these 3D rock images are used to understand fluid and matter floods.
