Effect of Reservoir Structural Rhythm on Carbon Capture and Sequestration (CCS) Performance

In addition to the evolution of green and nano energy, sequestration CO2 is also an evolving method control global footprint greenhouse effect. Carbon Capture Sequestration (CCS) established technique capture carbon from anthropogenic sources, such as power chemical plants, then inject same in subsurface rock micropores, permanently store CO2. Besides its environmental credentials, CCS offers economic opportunities Gas Enhanced Oil Recovery Methane displacement coalbed reservoirs. process incorporates various geological, geometrical engineering understandings porous media fluid dynamics. Previous investigators have identified low permeability a better site for CCS. However, little known propagation effectiveness reservoirs that multiple layers sedimentation, vis-à-vis well topology density, flow direction, storage site, optimisation. reality, these altogether form structural rhythm gradient. this study, we investigated rhythms gradients optimise by using two objective functions (Darcy interstitial flowrates) 15 criteria (such pore size, porosity, tortuosity, aspect ratio). An experimental has been applied. Five analogous reservoir core samples with varying parameters tested. The results indicate optimisation responsive parameters. analysis study suggests gas requires compound positive porosity negative gradients. That is, injection wells should be placed area relatively (3%) large size (6000nm), while at high (20%) smaller (200nm). This can directly applied practice, that, given layered reservoir, engineers predict placement or would optimize some essential performance objectives
