реферат:
An invaded zone forms when mud filters into a permeable formation during and after drilling. The mud filtration process is affected by mudcake buildup, well pressure overbalance, and mud properties. Mud invasion changes the spatial distribution of resistivity in the near-wellbore zone - data that could be estimated from inverting the results of resistivity logging data. Invasion simulation can be used to predict invasion depth, mudcake thickness, distribution of resistivity, and formation permeability.
