Provided are systems and methods that relate to separating drilling waste fluids. A method for separating a drilling waste fluid, the method comprising: introducing the drilling waste fluid into a thermal extraction chamber; allowing the drilling waste fluid to flow longitudinally along two screws disposed within the thermal extraction chamber, wherein each screw comprises a shaft, a first flite segment, and a first kneading block sequence; allowing the geometry of the screws to separate drilling waste fluid into evaporated fluid and solids; removing evaporated fluid through a first outlet port; removing solids through a second outlet port. A thermal extraction chamber for separating drilling waste fluids, wherein the thermal extraction chamber comprises: barrel; first screw; second screw, wherein first screw and second screw comprise identical profiles, wherein first screw and second screw comprise shaft, first flight segment, and first kneading block sequence; inlet port; first outlet port; second outlet port.
