DIGITAL ROCK TECHNOLOGY FOR ACCELERATED RCA AND SCAL: APPLICATION ENVELOPE AND REQUIRED CORRECTIONS
Digital Rock Physics or
Digital Rock is a rapidly advancing image-based technology for predicting subsurface
properties of complex rocks (e.g., porosity, permeability, formation factor) to
achieve more, cheaper, and faster results as compared to conventional
laboratory measurements. We show that a combination of limited image resolution
and a finite field of view, leads to the systematic underestimation of porosity
and overestimation of permeability calculated using Digital Rock technology. We
quantify these effects and derive the necessary corrections to estimate the
true rock properties directly from the segmented micro-CT image. These novel
solutions allow us to further mature DRP as a technology for existing and
Nishank Saxena is a Research Petrophysicist in Subsurface Interpretation Technology group in Shell. Nishank leads Digital Rock technology activities in Houston with an aim to accelerate exploration and development decisions using novel digital/imaging tools while managing risks in the subsurface. Nishank holds a MS and a PhD in Geophysics/Rock Physics from Stanford University. In 2016, Society of Exploration Geophysicists (SEG) recognized Nishank’s contributions to geophysics as an early career scientist with the J. Clarence Karcher Award.
