|dc.description.abstract||To increase the successful rate of acid stimulation, a method is required to
diagnose the effectiveness of stimulation which will help us to improve stimulation
design and decide whether future action, such as diversion, is needed.
For this purpose, it is important to know how much acid enters each layer in a
multilayer carbonate formation and if the low-permeability layer is treated well.
This work develops a numerical model to determine the temperature behavior for
both injection and flow-back situations. An important phenomenon in this process is the
heat generated by reaction, affecting the temperature behavior significantly. The result of
the thermal model showed significant temperature effects caused by reaction, providing
a mechanism to quantitatively determine the acid flow profile. Based on this mechanism,
a further inverse model can be developed to determine the acid distribution in each layer.||
