... an integrated model in both the microscopic and macroscopic scale to simulate multistage acidizing treatments in limited-entry and open-hole long horizontal wells. We propose a modified semi-analytical model to describe the wormholing phenomena and chemical diversion by using core flow test data. The reservoir...

.... Conventional reservoir models can not handle this level of complexity. A new, 3-D, four-phase, nonisothermal, multiwell black oil and Pseudo-compositional simulator that allows placement of multiple transverse fractures along the horizontal has been developed. Its ability to model horizontal, multiwing...
