Title : An Analytical Model For Characterizing Dynamic Filtration Of Drilling Fluid In Oil And Gas Wells
Aruna Singh, M Aslam Abdullah, Bandaru Kiran

Abstract :

Problem of formation damage in oil and gas industry is very much significant and more efforts are needed to mitigate it. Reservoir engineers should have idea about the potential and nature of the formation damage. With the help of mathematical model for the cake build-up engineers can reduce this problem. There are many mathematical models for cake build up in wells. With these models MATLAB program is created. This program takes 8 parameters from user and provide data such as in cake thickness, filtrate volume escaped through the well. Graph are plotted by changing one parameter while keeping others constant. The graphs obtained help to understand relationships between different parameters such as viscosity of filtrate, pressure drop and volume fraction of solid in mud. Results show that increasing viscosity, volume fraction of solid in mud decreases formation damage. The data for three different wells were considered in different parts of the country. Whereas increasing pressure drop increases the formation damage. By controlling these parameters we can reduce the formation damage.
