چکیده:

In many wells, the requirement from the operator is to be able to produce the well with the minimum number of interventions and treatments, ideally by just reversing the pressure drop between the well bore and the formation. Depending on the amplitude of this pressure drop,
the permeability of the reservoir rock and the nature of the drilling mud employed, it has been shown that the filter cake can fail.
This study wants to find experimentally the effects of filtration pressure, flow rate and permeability on filter cake removal. A simple model of filtration cell was designed and constructed. Different rock samples were used for investigating the permeability effect on filter cake removal. Statistical software was defined and used for modeling the experimental data to achieve a quantitative conclusion about filter cake removal and parameters effected on.
