An apparatus and method for increasing and regulating temperature, pressure and fluid viscosities of fluid streams found in oil and gas production. The apparatus may heat fluids flowing from the reservoir to the surface, or heat fluids injected from the surface into the reservoir. The apparatus includes an elongated, polygonal shaped tubular heating member with a plurality of fins radially extending from the flat surfaces of the polygonal shaped member, a tubular mixing member axially aligned with the polygonal shaped tubular member, said tubular mixing member having apertures therein and a shroud enclosing said polygonal shaped heating member and tubular mixing member. In one embodiment, the tool comprises a plurality of polygonal shaped heating members and tubular mixing members, axially aligned in alternating series.
