The production of oil and gas is being challenged by increasingly difficult conditions. In many cases, conventional technologies no longer meet the requirements of the oilfield engineer or regulatory bodies. AkzoNobel has developed a unique stimulation fluid with high thermal stability and low corrosion potential which is both effective and environmentally friendly.
As a standalone fluid Dissolvine StimWell improves the permeability of both carbonate and sandstone formations by dissolving calcium carbonate and controlling iron at the same time.
Dissolvine StimWell combines the effectiveness of widely used acids such as hydrochloric acid (HCl) or mud acid with the ability to dissolve or prevent most types of problematic scales.
This double functionality makes Dissolvine StimWell an excellent acid stimulation fluid for both carbonate and sandstone reservoirs. As a standalone fluid it improves the permeability of these formations by dissolving calcium carbonate and controlling iron at the same time. In combination with HCl or mud acid, Dissolvine StimWell can serve as an iron controlling agent and prevent scale and sludge formation.
