Abstract. The processes that occur during the construction of wells have significant and often irreversible effects on the well productivity index. During drilling and completion, mud filtrate and different mud components (particles, clay, polymers and etc.) invade into the near-wellbore zone of the reservoir due to the ‘over-balance’ pressure and interact with the reservoir fluids and rock-forming minerals. As a result, these processes can cause significant changes of reservoir properties in the effected region and lead to higher values of skin factor. In this paper, we consider a numerical model of near-wellbore zone, which includes generation and growth of the external mud cake and invasion of the drilling mud filtrate. The dynamics of the near-wellbore zone and the well production have been studied in order to determine its dependence on the basic physical properties of reservoir, drilling mud properties and the perforation length.
Keywords: drilling, near-wellbore area, mud losses, clogging, external mud cake, internal mud cake, skin-factor, cleanup of near-wellbore zone.
