  This article provides an overview of the current state of digital rock
technology, with emphasis on industrial applications. We show how imaging and
image analysis can be applied for rock typing and modeling of end-point
saturations. Different methods to obtain a digital model of the pore space from
pore scale images are presented, and the strengths and weaknesses of the
different methods are discussed. We also show how imaging bridges the different
subjects of geology, petrophysics and reservoir simulations, by being a common
denominator for results in all these subjects. Network modeling is compared to
direct simulations on grid models, and their respective strengths are
discussed. Finally we present an example of digital rock technology applied to
a sandstone oil reservoir. Results from digital rock modeling are compared to
results from traditional laboratory experiments. We highlight the mutual
benefits from conducting both traditional experiments and digital rock
modeling.
