Matrix acidizing modeling of near-wellbore with reduced reservoir properties (part 2)

Authors: K.A. Turegeldieva, U.K. Zhapbasbayev, B.K. Assilbekov (Kazakh-British Technical University, Kazakhstan, Almaty), A.B. Zolotukhin (Gubkin Russian State University of Oil and Gas, RF, Moscow)

Key words: acid stimulation, damage function, wormhole, Damkohler number

This paper deals with two-scale numerical modeling of the carbonate rock dissolution using hydrochloric acid. In order to account the reduced reservoir properties due to of the near-wellbore zone damage, a special function fd characterizing reservoir damage introduced in the numerical calculations. The influence of fd function on process of rock dissolution depending on the Damkholer number is analyzed based on numerical modeling. The optimal regimes of damaged and undamaged carbonate rock dissolution were determined.
