Field Application of A Method for Waterflooding

Abstract

314-317A field investigation, developed from laboratory test, conducted to identify and understand magnetic effects on oil recovery during waterflooding process at several oil fields in Azerbaijan. Results of the initial field testing of this improved oil recovery (IOR) method show, that magnetisation increases rock wettability, injectivity, as well as the flow capacity of porous media and favours degassing of water. The additional oil produced is attributed to the above factors and buoyant oil flow created by suction force of the magnetic type. Pressure stabilises easily during pressure buildup, scaling from formation water reduced by 80-97 per cent, downhole corrosion reduce by 35-40 per cent and clay swelling minimise by the constant transverse magnetic field. The results reavel that the method is novel are usel for studying magnetic fields
