Formation invasion plays an important role in the modern drilling practices. The well completion and production cost play more and more important role as the petroleum industry meets new challenges. The well completion and stimulation cost can be reduced if the mud?s effect on the hydrocarbon-bearing formation is clearly known and can be modeled at the well design phase. Better mud selection leads to lower cost in the completion phase. Proper mud selection can be supported by early reservoir analysis based on previous geological data and using artificial core samples. A new artificially consolidated sandstone producing technique was established to meet the different requirements of the petroleum reservoirs: core samples having different porosity and permeability can be produced routinely. Moreover, HPHT dynamic filtration simulation is possible using the newly equipped special core sample holder where different pressure differences can be applied on the core samples. Conventional drilling mud was used to damage the formation and after the flooding process, alterations of the initial petrophysical parameters were analyzed. Results show that artificial core samples can be used to simulate the mud?s effect on the well?s final productivity.
