Acidizing/stimulation
This paper presents the application of degradable particulate-diverter technology to improve oil production by effectively diverting stimulation treatment fluids away from high-water-cut, high-permeability, high-temperature producing intervals or zones.
The creation of SPE’s Acid Stimulation Technical Section shines a light on the technique that improves injectivity and productivity. JPT talked with the chair of the new section about the importance of the technical area.
The Acid Stimulation Technical Section aims to provide a global home for engineers, scientists, researchers, and practitioners working on acid stimulation in carbonate and sandstone reservoirs.
