Micro-scale modeling of formation damage

In this dissertation we study both permeability damage mechanisms - particle entrapment and grain crushing - through a micro-scale modeling approach. In order to study the first permeability damage mechanism, i.e. solid particle entrapment, this dissertation provides a novel workflow for micro-scale modeling of particle entrapment due to straining in porous media based on first principles.

Feldspar thermometry in pegmatites: truth and consequences | …

 · Temperatures of crystallization for all or portions of three thin granitic pegmatite dikes in southern California are derived from feldspar solvus thermometry, with supporting data from the K/Cs ratio of K-feldspar, the extent of Al/Si order in K-feldspar, and the texture of granophyre found along the margins of dikes. Although K-feldspars become perthitic and increasingly ordered toward the ...
