Dewaxer flow enhancer system and method
A dewaxer flow enhancer. The dewaxer flow enhancer provides heat to the crude oil within tubing of a well bore in a drilling operation and collects the wax in a swab cup. The dewaxer flow enhancer includes a body having a head and a dewaxing barrel. The dewaxing barrel delivers heat via an induction heater and includes a tip that forms a path for the dewaxer flow enhancer as it oscillates and reciprocates within the tubing. Once sufficiently heated, wax in the crude oil has a lower viscosity and is collected via a swab cup of the head. An actuator is coupled to the dewaxer flow enhancer via a slickline or e-line and controls the position within the tubing. A controller regulates the heat and sensors detect properties of the crude oil.
