THE EFFECT OF SILICA DISSOLUTION ON PERMEABILITY IN WATER AND ALKALINE INJECTION
Silica scale formation is one of many scales that are encounter during oil production. It can deposit in the well tubing, causing equipment failure and also within the reservoir near the production well. This will reduce the overall effective permeability and ultimately effects the total production...
