In Oil and Gas industry operations, scale deposition on the surface and subsurface production equipment can cause different problems such as formation damage, loss in production, pressure reductions, and premature failure of down hole equipment. Due to geochemical processes between injection water , connate water and rock, the complex composition of reservoir fluids make it difficult to control the inorganic scale formation. Carbonate (calcium), sulfide (iron, zinc), and sulfate (calcium, barium, strontium) scales are more common in oilfield applications, specifically oilfield scales are calcium carbonate ( limescale ), iron sulfides, barium sulfate and strontium sulfate. The scale formation depends on several factors that include, but are not limited to, temperature, pressures, solution saturation and hydrodynamic behavior of the flow. Oilfield scaling is the precipitation and accumulation of insoluble crystals (salts) from a mixture of incompatible aqueous phases in Oil processing systems. Aquapharm manufacture and supplies Oilfield chemicals prevent scaling due to the mixing of incompatible injection water and formation water. Aquapharm offers oilfield chemicals for dissolving different types of inorganic deposits. The anti-scalants used are from our range of phosphonates, polymers , biodegradable chelants and biodegradable polymers.
