Proprietary speciality chemicals for downhole applications requiring acidising, polymer breaking, removal of hydrocarbons, sand consolidation or fluid shut off. Includes fluids for in-situ production of acid after the treatment fluid has been placed. This gives excellent acid placement and zonal coverage across long horizontal wellbores and deep into oil/gas reservoirs. Products are used to treat; oil and gas production wells; water and gas injection wells and water production wells. Key applications include: Treatment of formation damage; Treatment of drilling fluid damage from water based or oil based muds and drill-in fluids; Deep matrix acidizing of carbonate formations; Stimulation of natural fracture networks in carbonate formations; Acidizing poorly consolidated sandstone formations. Products are low hazard, low environmental impact, derived from renewal resources, easy to use and are highly effective. Principal Customers/Markets Upstream oil & gas operating Companies worldwide.
