Review of Particle Detachment and Attachment in Porous Media

by

Naomi Amoni Ogolo and Mike Onyekonwu

ABSTRACT
Particle detachment, migration and attachment are common processes in porous media, especially in unconsolidated formations. In this review, the processes are discussed and equations describing the processes are presented. Two particle detachment processes analyzed are the hydrodynamic forces and electric double-layer forces. The particle detachments equations were critically examined to determine if they reflect crucial factors that trigger particle detachment in porous media. Essential factors that are missing in the equation are the effect of pressure and the level of rock consolidation. Incorporating the level of rock cementation and the effect of pressure in the equations will make the models more empirical and less theoretical. For particle attachment, Van der Waals forces, adhesion, particle attachment efficiency, and straining processes and their equations are considered. The colloidal forces are all embraced in terms of capturing important elements that mobilize particles in porous media, however, the practical application of the models can pose a challenge. For particle adsorption on grain surfaces, it is recommended that the effect of pressure and temperature be studied.

The paper is readily available to interested readers, it can be access at

Abstract
Monosaccharide derived glucose-aspirin (GA) can be prepared by conjugation between glucose and aspirin (ASA). The GA is reported to show higher analgesic and anti-inflammatory properties than ASA itself. In this perspective, six GAs which are composed of β-D-glucopyranose, ASA and acetyl groups are considered for the present investigations. The glucose unit in these GAs possesses regular chair conformation with slightly lower dipole moments. Molecular orbitals indicated a higher HOMOLUMO gap of the molecules. All GAs showed more prone to electrophilic interactions than aspirin. Overall, glucose-aspirin esters are found to have better non-steroidal anti-inflammatory properties than the original aspirin. These GAs are better inhibitors of cyclooxygenase-2 (COX2, 5f19) compared to cyclooxygenase-1 (COX1, 6y3c) indicating that these GAs are potential drug candidates for COX2 related inflammation. Additionally, aspirinyl group at C-6 or C-3 position of the glucopyranose unit is found more suitable for anti-inflammatory activities as compared to C-4 position.
