Geological factors affecting CO2 plume distribution

Stochastic Analysis of Factors Affecting the Leakage of Co2 from Injected Geological Basins

Source Remediation vs. Plume Management: Critical Factors Affecting Cost-efficiency

This summary paper reviews just some of the extensive scientific literature from the past 20 years on the various aspects of contaminant source remediation and plume management. Some of the major findings of the numerous research projects are presented. The first section outlines the controlling mass transfer mechanisms which need to be considered for any in situ source remediation technology. ...

Some Geomechanical Aspects of Geological CO2 Sequestration

Reservoir depletion and subsequent CO2 injection into the depleted geological reservoir induce stress changes that may mechanically damage top seal and wells, or trigger existing faults, creating the leakage pathways for CO2 escape from the reservoir. The role of geomechanics is to assess the mechanical impact of stress changes on seals, wells and faults. Since many hydrocarbon fields are geome...

Geological and Physical Factors Affecting the Friction Angle of Compacted Sands

This study evaluated the effects of physical characteristics and geologic factors on the shear strength of compacted sands from Wisconsin that are used as granular backfill for mechanically stabilized earth walls and reinforced soil slopes. Physical properties and shear strength were determined for 30 compacted sands collected from a broad range of geological deposits. Relationships between str...

Factors affecting the distribution of cytoplasmic incompatibility in Drosophila simulans.

In Drosophila simulans a Wolbachia-like microorganism is responsible for reduced egg-hatch when infected males mate with uninfected females. Both incompatibility types have previously been found in North America, Europe and Africa. Some California populations have remained polymorphic for over two years, and the infection is apparently spreading in central California. Egg hatch proportions for ...
