Complexities in pore scale structure, rock-fluid and fluid-fluid interactions have a profound effect on the estimation of reserves, reservoir recovery and productivity in reservoir core material. These complexities determine the pore scale distribution of fluids within the pore space, which, in turn, determine the petrophysical response of the rock. A very important example is the estimation of...

Adopting sustainable strategies to manage water resources of karst reservoirs requires understand the carbonate rock reactivity that is responsible for formation these reservoirs, as well role mineralogy in conduit formation. To this end, three rocks (chalk, crinoidal limestone and dolomite) with different internal structure are submitted laboratory dissolution experiments by injecting an acid ...

wettability alteration is one of the most important methods for oil recovery from sandstone andcarbonate reservoirs. the effects of salinity, ph, temperature, and chemicals such as surfactants andfatty acids on the alteration of the wettability were described in previous studies. in recent years,attention has been directed to nanoparticles as a wettability alteration agent. the effect of somena...

In some of the challenging digital rock applications trade-off between model resolution and representative elemental volume is not captured in a single satisfying minimum requirements for both aspects. wide range lithofacies found carbonate reservoir rocks, facies fall this category, where large pores, ooids or vugs, are connected by small scale porous structures that could have orders magnitud...

[1] A rock magnetic cyclostratigraphy, based on anhysteretic remanent magnetization (ARM) intensity variations, was developed for the Eocene Arguis Formation in the Spanish Pyrenees. The Arguis Formation was sampled for ARM cyclostratigraphy, rock magnetic, and paleomagnetic analyses. Rock magnetic measurements indicate that the dominant magnetic mineral controlling the ARM cyclostratigraphy is...
