Shale pore alteration: Potential implications for hydrocarbon extraction and CO2 storage

Do Shale Pore Throats Have a Threshold Diameter for Oil Storage?

In this work, a nanoporous template with a controllable channel diameter was used to simulate the oil storage ability of shale pore throats. On the basis of the wetting behaviours at the nanoscale solid-liquid interfaces, the seepage of oil in nano-channels of different diameters was examined to accurately and systematically determine the effect of the pore diameter on the oil storage capacity....

CO2 Storage Capacity for Multi-Well Pads Scheme in Depleted Shale Gas Reservoirs

As a promising technology to improve shale gas (SG) recovery and CO2 storage capacity, the multi-well pads (MWPs) scheme has gained more and more attention. The semi-analytical pressure-buildup method has been used to estimate CO2 storage capacity. It focuses on single multi-fractured horizontal wells (SMFHWs) and does not consider multi-well pressure interference (MWPI) induced by the MWPs sch...

Screening and Ranking of Hydrocarbon Reservoirs for CO2 Storage in the Alberta Basin, Canada

Human activity since the industrial revolution has had the effect of increasing atmospheric concentrations of gases with a greenhouse effect, such as carbon dioxide (CO2) and methane (CH4), leading to climate warming and weather changes (Bryant, 1997; Jepma and Munasinghe, 1998). Because of its relative abundance compared with the other greenhouse gases, CO2 is by far the most important, being ...
