Zusammenfassung:	A method to increase the volume of a wellbore, said method comprising: - providing a wellbore located within a rock formation; - providing a modified acid composition comprising at least two components: a first component being an amino acid and a second component being a mineral acid; wherein said first component and second component being present a molar ratio ranging from 1:3 to 1:12.5; - injecting said modified acid composition into said wellbore at a pressure below fracking pressure; - allowing the modified acid composition to be in contact with the formation for a period of time long enough to allow the modified acid to create a series of wormholes and consequently increase the surface area fluidly connected to said wellbore to enhance the absorption capacity of carbon dioxide injected into said wellbore.
