Microscale effect of microvadose in shale reservoirs
Petroleum Exploration and Development, 2014 There are abundant nanopores in the organic matter of shales. Gas flow in nano-pores leads to micro-scale effect that can't be described by flowing law of macro fluid. The Lattice Boltzmann Method was applied to simulate gas flow in the nano-channels of organic matter and the effect of slippage, diffusion and adsorption/desorption were considered.

Quantitative Insights into Atomic Scale Oil–Clay Adhesion Governing Shale Oil Retention and Mobility
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Atomic force microscopy reveals a clear adhesion hierarchy between shale oil and clay minerals, governed by nanoscale surface chemistry. Strong interactions on chlorite and illite arise from abundant polar sites and cation bridging, whereas weaker coupling on montmorillonite limits interfacial binding.

Energy Science &Engineering, EarlyView.Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

Greenhouse Gases: Science and Technology, EarlyView.ABSTRACT Legacy wells represent a critical consideration for offshore CO2 storage projects, as they may provide potential pathways for fluid or gas migration if poorly constructed, undocumented or inadequately abandoned. Systematically assessing large numbers of legacy wells remains challenging due to heterogeneous data availability and the diversity ...
