Abstract
Methods for treating a producing wellbore of a subterranean reservoir include obtaining a side stream flow of a produced fluid from a production tube of the wellbore at a location above the surface of the earth; providing an eluting contact of the side stream flow of produced fluid with a treatment material to form a side stream flow of treated produced fluid; and directing the side stream flow of treated produced fluid into the wellbore at a point below the surface of the earth. Apparatuses suitable for carrying out the methods include an elution device fluidly connected to a side stream of produced fluid flowing above the surface of the earth and situated to direct the side stream toward the elution device to provide an eluting contact of the produced fluid with a treatment material disposed in the elution device, then direct the treated produced fluid into the wellbore.
