Rock on Chip (ROC) is a new technology to perform experiments to test and refine properties, new materials, and methods for enhanced recovery in conventional and unconventional reservoirs. The Rock on Chip technology goes a step beyond traditional digital rock physics. The Rock on Chip technology uses the pore or fracture geometry derived from digital rock model and fabricates it onto a custom-coated silicon chip. Testing and refining new materials and processes at the field scale are expensive, time-consuming and often in-conclusive. The Rock on Chip technology provides a rapid, small scale, conclusive method to test and refine materials and processes to experimentally and effectively stimulate reservoir for enhanced recovery through use of new surfactant, new proppants or fracturing fluid, CO2/N2 for huff & puff.

The flow through experiments are performed in the Lab on Chip (LOC) that consists of a high resolution imaging system, a highly sensitive ow controller and ow sensing system with femtoliter resolution in order to measure key properties related to transport of fluids at nano-scale. The conventional simulators that use physics based on Darcy’s law for permeability and conventional EOS for PVT properties, fail to add the complexity of pore-wall– fluids interaction in calculating transport and thermodynamic properties of hydrocarbon fluids in shales. The customized Rock on Chip that replicates the actual geology of the relevant formation provides useful insights into transport and thermodynamic properties in nanoporous rocks.
