ATTENUATED ACID FORMULATIONS FOR ACID STIMULATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17548752 titled 'ATTENUATED ACID FORMULATIONS FOR ACID STIMULATION
Simplified Explanation
The abstract describes a method for acid treating a carbonate reservoir using an attenuated acid formulation. The method involves mixing an acidic compound with a hygroscopic chemical to create the attenuated acid formulation, which is then injected into a carbonate formation.
- The method involves acid treating a carbonate reservoir.
- An attenuated acid formulation is used, which is created by mixing an acidic compound with a hygroscopic chemical.
- The attenuated acid formulation is injected into the carbonate formation.
Potential Applications
- Enhanced oil recovery in carbonate reservoirs.
- Acid stimulation of carbonate formations to increase permeability.
- Acidizing wells to remove formation damage in carbonate reservoirs.
Problems Solved
- Acid treating carbonate reservoirs can be challenging due to the high reactivity of the acid with the carbonate rock.
- The use of an attenuated acid formulation helps to mitigate the reactivity and prevent excessive dissolution of the carbonate rock.
- The method provides a more controlled and effective acid treatment for carbonate reservoirs.
Benefits
- Improved acid treatment of carbonate reservoirs.
- Reduced risk of excessive dissolution and damage to the carbonate rock.
- Enhanced permeability and production from carbonate formations.
Original Abstract Submitted
A method for acid treating a carbonate reservoir with an attenuated acid formulation is provided. The method includes mixing an acidic compound with a hygroscopic chemical to form the attenuated acid formulation, and injecting the attenuated acid formulation into a carbonate formation.
