    摘要: A method for determining a Plug Normal Stress Difference (ΔN1(P)) may include providing a test base drilling fluid that is characterized by N1(TB); adding a first concentration of a test particulate to the test base drilling fluid; adjusting the concentration of the test particulate in the test base drilling fluid to achieve a minimum concentration of the test particulate in the test base drilling fluid that will substantially plug a tapered slot, wherein the test base drilling fluid with the minimum concentration of the test particulate is characterized by N1(TA); and calculating ΔN1(P)=|N1(TA)|−|N1(TB)| wherein each First Normal Stress Difference is measured by the same procedure.

    摘要: Apparatus and methods for simulation of bore hole fractures are disclosed. A device for simulating a fracture in a subterranean formation comprises a housing, an inlet for directing a sample fluid to the housing, and a first disk and a second disk positioned within the housing. The second disk is movable relative to the first disk to form an adjustable gap between the first disk and the second disk and the sample fluid flows through the adjustable gap. A common collector receives at least a portion of the sample fluid that flows through at least one of the first disk and the second disk.

    摘要: A method for the removal of soluble metal ion contamination from fluids is disclosed. The method includes passing the contaminated fluid through a filter medium comprising a reducing metal and a filter aid, such as diatomaceous earth, and collecting a filtrate with lower concentration of soluble metal ion contamination. The reducing metal can have a reduction potential of from −0.50 volt to −3.10 volt and can be capable of reducing the soluble metal ions to insoluble metal, which can then be entrapped in the filter medium or otherwise separated.

    摘要: A plasma reactor with plasma confinement and plasma radial distribution capability. The reactor comprises a reactor chamber including a side wall and a workpiece support pedestal in the chamber and defining a pumping annulus between the pedestal and side wall and a pumping port at a bottom of the pumping annulus. The reactor further comprises a means for confining gas flow in an axial direction through the pumping annulus to prevent plasma from flowing to the pumping port. The reactor further comprises a means for compensating for asymmetry of gas flow pattern across the pedestal arising from placement of the pumping port. The reactor further comprises a means for controlling plasma distribution having an inherent tendency to promote edge-high plasma density distribution. The means for confining gas flow is depressed below the workpiece support sufficiently to compensate for the edge-high plasma distribution tendency of the means for controlling plasma distribution.
