Formation damage due to fines migration and its remedial methods

Well testing analysis and well performance analysis were done to detect formation damage and provide an overall measure of formation damage. Laboratory core flood tests had been used to determine the causes, degree, and extent of damage. Scanning electron microscopy (SEM) was used to analyze the rock samples used for the core flood test before and after the test. Core flood test had been done to evaluate the effect of acid on improving and curing damaged cores. Matrix acid stimulation on a case study from the studied field was evaluated.
