Viability study of a system for filtercake remotion in pay zone of oil wells
This article describes the essential ideas of an experimental procedure performed in order to check the filter-cake removal system is suitable for use like filter-cake removal system for pay zone. This system is made on aqueous phase and its concentration depend of the quantity of filtercake estimated in the wellbore of horizontal wells. This optimized the wellbore cleaning and increase the worth of well. The results of tests show that system could work, but it needs further analysis for determine the compatibility with fluids and rock from reservoir.
