Method of optimizing the design, stimulation and evaluation of matrix treatment in a reservoir

A method for modeling a stimulation treatment for a reservoir, comprising the steps of:

• a. obtaining a set of quantified reservoir parameters including the reservoir minerals, permeability and the quantity and depth of damage to the reservoir;
• b. modeling a reservoir core having a length and a diameter;
• c. designing a first treatment fluid comprising a mixture of chemical species;
• d. obtaining a first set of chemical reactions that can occur between the minerals and the component of the treatment fluid;
• said reactions defined by their equilibrium and their kinetic properties;
• e. selecting an injection rate of the treatment fluid;
• f. selecting a subset of said first set of chemical reactions to create a reaction model of said core with said treatment fluid and predict damages consecutive of the treatment;
• and
• g. iteratively adjusting the stimulation treatment to optimize results.
