Acid fracturing - PetroWiki


Designing an acid-fracturing treatment is similar to designing a fracturing treatment with a propping agent. Williams, et al.[1] presents a thorough explanation of the fundamentals concerning acid fracturing. The main difference between acid fracturing and proppant fracturing is the way fracture conductivity is created. In proppant fracturing, a propping agent is used to prop open the fracture after the treatment is completed. In acid fracturing, acid is used to "etch" channels in the rock that comprise the walls of the fracture.
