SIMULATION OF SANDSTONE MATRIX ACIDIZING IN HETEROGENEOUS RESERVOIRS. Conference Paper

abstract

• A numerical simulator was developed to predict porosity and permeability changes, and the resulting effect on well productivity in sandstones subject to matrix acidizing. While earlier acidizing models are based upon homogeneous porous media, here vertical variation in permeability was accounted for by considering several non-communicating zones or layers with different overall permeability-height (kh) products. With this model the effect of injection rate on acid penetration distance and on diverting agent efficiency was investigated. Acidization results in a heterogeneous porous media are compared with results obtained for a vertically homogeneous porous media.
