Investigating the Effect of Fluid and Formation Parameters on Mud Cake Thickness, Filtration Velocity and Invasion Depth
Mud cake formation is a layer of mud emulsion that is formed from the drilling fluids during the drilling operation. Filtration process of drilling mud takes place as the drilling operation in carried out under a certain condition called overbalanced conditions, which means that the pressure of dril...

Mud cake formation is a layer of mud emulsion that is formed from the drilling fluids during the drilling operation. Filtration process of drilling mud takes place as the drilling operation in carried out under a certain condition called overbalanced conditions, which means that the pressure of drilling mud injected is higher than the pressure of the formations. Due to this differential in pressure, drilling fluids will tend to be invaded into the porous part of the formation; where by the smaller particles of the drilling fluid will invade further into the formation, while the larger particles will accumulate at front surface of the pore size, creating a layer of mud cake. Understanding the behavior of mud cake thickness is important because it can reduce the mud circulation loss into the formation. Specifically, they are few objectives to be achieved within this project.
