Abstract: Methods and systems that may be employed to dynamically test the effect of fluids (e.g., well treatment chemicals such as well stimulation treatment chemicals, enhanced oil recovery “EOR” chemicals, etc.) on hydrocarbon recovery from crushed reservoir formation materials under conditions of applied stress. The disclosed methods and systems may be used in one embodiment to dynamically test types of low permeability formations (e.g., such as shale, limestone, quarried rock, etc.).

Abstract: A chaff spreading apparatus is adapted to be functionally mounted to conventional combine threshing machines in a manner to perform a secondary chopping and spreading of straw and chaff exiting the rear of the threshing machine that somehow bypass the threshing machine primary straw spreaders. The chaff spreading apparatus comprises a pair of rotating wheels or disks, each having a plurality of blades mounted thereon for catching, cutting or chopping, and scattering straw or chaff exiting the threshing machine. The disks are positioned for rotation in an essentially horizontal plane generally below and slightly behind the straw and chaff exit chute of the threshing machine in a manner to catch all of the straw and chaff sliding down the chute and chop and scatter same to the rear and sides of the threshing machine.
