Abstract
Methods of stimulating a hydrocarbon reservoir having carbonate components are described herein. An acid treatment material is developed by defining a diversion parameter as a ratio of volume of diversion material to be used for treatment of the reservoir to volume of fractures to be developed during acid treatment of the reservoir, defining a relationship between the diversion parameter and a diversion result, selecting a value of the diversion parameter based on the relationship, determining an amount of diversion material based on the selected value of the diversion parameter, and adding the amount of the diversion material to an acid treatment material. The reservoir is then subjected to acid treatment using the acid treatment material.

A method of treating a hydrocarbon reservoir having acid-susceptible components, the method comprising:
- defining a diversion parameter as a ratio of volume of diversion material to be used for a reservoir treatment to volume of a perforation-fracture system to be developed during acid treatment of the reservoir;
- defining a relationship between the diversion parameter and a diversion result;
- selecting a value of the diversion parameter based on the relationship;
- determining an amount of diversion material based on the selected value of the diversion parameter;
- forming an acid treatment fluid comprising the amount of the diversion material;
- and
- applying the acid treatment fluid to the hydrocarbon reservoir.
