Abstract. The drilling mud-filtrate invades into a reservoir is a dynamical process after a formation was opened in oil exploration. Since the invasion profiles of formation resistivity vary with time, the invasion depth is related to time. The fluid flow equations were used to calculate the invasion profiles and invasion depth. The present dynamic invasion model generated the time-dependent formation resistivity profiles and invasion depth. The effects of two main parameters, porosity and permeability, for a permeable and porous formation were studied. The invasion depth increases with the growing permeability and decreasing porosity.

Abstract. Traditional invasion correction tornado charts for dual-induction log was based on the step-invasion profiles that is different from a realistic invasion process. The dynamic invasion correction charts can be obtained from the dynamic invasion responses of dual-induction logs. The invasion time was introduced as an important parameter during the correction process. The initial water saturation in a reservoir can be directly obtained from the present charts.

“…Also, the mudcake thickness will increase to an equilibrium value. Lots of studies predict and simulate the behavior of the filtration process (J. T. Dewan and M. E. Chenevert, 2001;Windarto et al, 2011). In those models, a linear system has been considered but since the borehole and the reservoir are like a cylindrical system, the simple Darcy equation in radial coordinate system is used for developing the model described in this paper.…”

Drilling mud plays an important role in drilling operations. Forming a thin layer called mudcake is one of these roles which prevents the aquatic phase of drilling mud called mud filtrate from penetrating through the reservoir rock and therefore reduces the damage caused by that work. So knowing about the mudcake characteristics such as thickness, solid contents and also filtration rate of mud filtrate will help the drilling engineer. Factors affecting filtration process are time, temperature and pressure. In this paper, a mathematical model will be presented which estimates mudcake thickness and filtration radius in both static and dynamic conditions with consideration a radial system at constant temperature conditions. The mudcake thickness and permeability variation with time are also considered in the dynamic model.
