Abstract
An electromagnetic fluid conditioning (EFC) apparatus and method to control paraffin and/or asphaltene is disclosed. Further, the present invention incorporates the discovery that the electric field must have specific characteristics to achieve the efficiency described herein. The invention disclosed is an apparatus and method for inducing a magnetic field parallel to the flow of fluid in the conduit at surface or downhole conditions and an electrical field orthogonal to the direction of the flow of fluid in the conductor. The magnetic and electrical fields have high magnetic and electric intensity, respectively. A high vibration frequency of the fields is achieved using high frequency AC current or high pulsed DC current. The apparatus and method controls the deposition of paraffin, asphaltene and other susceptible substances.
