Subsurface Sand Remobilization and Injection 2017

Evidence of sand fluidization and injection as significant shallow crustal processes is increasingly common in outcrop and subsurface studies. Regionally-developed giant sand injection complexes develop in areas of 100's to 1000's km2 and locally reservoir commercial volumes of hydrocarbons, act as fluid migration routes, compromise seals and record major periods of focused fluid flow. The non-stratiform character of sandstone intrusions requires original solutions for the successful quantitative modelling, drilling and completion of wells and accentuates the need for a better understanding of these often enigmatic features. Sand injection and fluidization occurs on many scales both within giant complexes and as small, discrete features. Presentations are invited that examine the characterization and interpretation of sandstone intrusions and associated facies, from granulometric - to regional-scale. Processes, modelling and practical applications are equally relevant as we consolidate knowledge from exploration and development drilling with the associated research and identify priority areas for future investigation.
