Abstract: A system for removing hydrocarbons and other contaminants from sand and/or drill cuttings includes screening large debris from a first loading inlet hopper (101) to a screen covered receiving hopper (102) that may contain a chopper and chemical additive nozzles (105). A first inclined auger (104) receives the material from hopper (102) at its lower inlet port and conveys the material upwards dropping it into a hopper (106) and then to a unit (107) either of which may include a crasher (106). Unit (107) includes an eductor (109) which feeds the screened and treated sand slurry to desanding units (112) such as hydro cyclones. The underflow from the desanders is sent to an auger tank's (114) first compartment (113) while the overflow is sent to its second compartment (115) where a flow distributing conduit (117) that disperses it over the surface of both compartments (113), (115). The auger tank (114) employs horizontal augers (116) that are arterial both the first and second compartments (113) and (114).

Abstract: A method for processing hydrocarbons recovered from a subterranean formation is disclosed. The method includes: feeding a stream including water, sand, and heavy hydrocarbons produced from a subterranean formation to a separation vessel; concurrently in the separation vessel: heating the stream components to an elevated temperature to reduce a viscosity of the heavy hydrocarbons; and separating the sand, the heavy hydrocarbon, and the water to form a water fraction, a hydrocarbon fraction, and a sand fraction comprising sand and at least one of water and heavy hydrocarbons; and recovering the water fraction from the separation vessel; recovering the hydrocarbon fraction from the separation vessel; and withdrawing the sand fraction from the separation vessel. Also disclosed are apparatus suitable for performing the above described method.

Abstract: A method of mixing drilling fluids, the method including injecting a drilling fluid into a high shear mixing unit and processing the drilling fluid with the high shear mixing unit. The processing includes forcing the drilling fluid through a first row of teeth of a first stage.

Abstract: A test kit for testing production waste includes a plurality of components including reagents, test equipment, or a combination thereof, sufficient to perform analysis on production waste and at least one protective case for shipping and for using the plurality of components, the protective case including a top portion releasably engaged with a bottom portion. The top portion includes a top side attached at an inner face of the top side to a top edge of a continuous sidewall formed by a plurality of sides such that the top portion of the protective case includes a hollow interior cavity bound by the inner face of the top side and an inner face of the continuous sidewall, wherein the hollow interior cavity is open on a bottom side, and wherein the hollow interior cavity defines a water-tight enclosure opened on the bottom side, such that the top portion, resting on a support surface inverted on an outer face of the top side, is capable of forming a liquid reservoir.

Abstract: A method of cleaning drilling fluid including providing a flow of drilling fluid to a treatment loop, determining a flow rate of the drilling fluid, and injecting a polymer into the drilling fluid based on the determined flow rate of the drilling fluid. Additionally, the method includes injecting a coagulant into the drilling fluid based on the determined flow rate of the drilling fluid and adjusting the rate of polymer and coagulant injection based on a change in the flow rate of the drilling fluid. Also, a method of controlling a drilling fluid cleaning system, the method including inputting a polymer dosage rate and a coagulant dosage rate into a system controller and providing instructions to the system controller.
