Formation damage had a significant impact on the overall performance of the well productivity. Removal of filter cake which deemed to be the main strategy of formation damage remediation. It was crucial in openhole completion with pre-slotted liner or stand-alone screen (SAS) as a mean of sand control. Without proper planning, inefficient filter cake removal could lead to tremendous consequences since filter cake could plug the sand control component. Making the condition worse, sand control component was susceptible to plugging. This highlighted the importance of selecting an effective filter cake breaker that could successfully remove the filter cake through dissolution of the main solids that constituted the major portions of the filter cake which could be the weighting material, barite or calcium carbonate. This paper intended to investigate the efficiency of 3 filter cake breakers in removing SBMDIF filter cake and analyze the mechanism of each filter cake breaker that impacted the performance of the filter cake breakers in removing the SBMDIF filter cake. The first of filter cake breaker consists of 50 vol.% Meso-surfactant based (acid), 30vol.% sodium chloride brine and 20%vol.% deionized water. The second filter cake breaker consists of 100 vol.% chelating-based (Alkaline) and the third filter cake breaker consists of 9.8vol. % nano-surfactant based (Alkaline) and 90.2vol.% of sodium bromide brine. High-pressure high-temperature (HPHT) filtration experiments were performed to evaluate the filter cake removal efficiency and the retained permeability. The Filter Cake Build-Up experiments were conducted using API – HPHT Filter Press at a temperature of 212 ◦F and 500 psi differential pressure to represent formation damage that occur in downhole condition and 100 ml Fluid Carrier Cell. Afterward, the filter cake that was formed was thin, with thickness of 5 mm and relatively lubricious. The SBMDIF filter cake was then soaked with the filter cake breaker solutions. The condition of the SBMDIF filter cake was visually inspected after the soaking treatment. Next, infectivity test was carried out to determine the time taken required for the base oil to pass through the treated SBMDIF filter cake. The obtained results showed that Filter Cake Breaker 1 had shown the best performance in removing the filter cake with 81% of the permeability was regain followed with Filter Cake Breaker 3 (73%) and Filter Cake Breaker 2 that had the lowest performance 51%). The new Meso-surfactant based system can be considered as an efficient solution for oil-based filter cake removal and cost-effective, where the reservoir permeability can be regained in one-stage only.
