A micro-core of Estaillades was then scanned using X-ray microtomography (μCT), the differential pressure was measured during single-phase flow, and the rock was flooded with doped brine. We found a good match between the experimental and simulated Mercury Intrusion Capillary Pressure (MICP) range in the imaged geometry and a good match between the imaged and object-generated permeabilities and MICP. ![]() The information from the nano-XRM scan was then used as input into an object-based pore network generator, on which permeability fields were simulated for a range of porosities, creating a synthetic Kozeny–Carman porosity–permeability relationship targeted for the specific microporous system present in Estaillades. ![]() First, a nano-core from a microporous grain of Estaillades limestone was scanned using nanotomography (nano-XRM). In this study, we use combined experimental, modeling, and pore space generation methods to tackle the impact of microporosity on the flow properties of Estaillades limestone. 4Zeiss Microscopy, Pleasanton, CA, United StatesĬarbonate rocks have multiscale pore systems that are weakly understood.3Math2Market GeoDict, Kaiserlautern, Germany.2Shell Global Solutions, The Hague, Netherlands. ![]() ![]()
