摘要: The present invention relates to artificially reducing the porosity of any potential flow paths in the near-wellbore region of a well or in permeable zones within or surrounding a well. In doing so, the permeability in this the targeted region will be significantly reduced, thus, preventing unwanted flow of subsurface fluids. The present invention concerns a method comprising applying a first and second solution comprising scale precursors to the porous media, wherein following this application, at least a portion of the scale precursors form at least two insoluble salts. Additionally, the present invention concerns a kit of parts comprising the first and second solutions.

摘要: A fluidic device (10) is described. The fluidic device (10) comprises the first part (110) and the second part (120). The first part (110) comprises a first inlet (111) and a first outlet (112), mutually spaced apart. The second part (120) comprises a first chamber (121) arranged to contain a predetermined first amount A1 of a first fluid F1 therein and a first wall portion (122) arranged to contain, at least in part, the first fluid F1 in the first chamber (121). The fluidic device (10) is arrangeable in a first configuration, wherein the first part (110) is fluidically isolated from the first chamber (121). The fluidic device (10) is arrangeable in a second configuration, wherein the first inlet (111) and the first outlet (112) are fluidically coupled via the first chamber (121), whereby increasing a first pressure P1 in the first chamber (121) via the first inlet (111) urges at least a part of the predetermined first amount A1 of the first fluid F1 through the first outlet (112).

摘要: A waveguide 200 for a leaky wave antenna 20 is described. The waveguide 200 comprises a male member 210 (210A-210T) and a corresponding female member 220 (220A-220T) arranged to receive the male member 210 (210A-210T) therein. The waveguide is arrangeable in a first configuration and a second configuration. The male member 210 (210A-210T) is received in the female member 220 (220A-220T) spaced apart therefrom in the first configuration and the second configuration. The first configuration defines a first effective delay line. The second configuration defines a second effective delay line. The first effective delay line is different from the second effective delay line. The leaky wave antenna 20 is also described.

摘要: A contrast element tracking method comprises obtaining a sequence of frames each comprising ultrasound or other medical imaging data representing an anatomical region of a human or animal subject at a respective different time; for each frame, identifying one or more portions of the ultrasound or other medical imaging data as single or multiple contrast element signal portions representative of a contrast element or plurality of contrast elements; assigning respective position data to each of the single contrast element signal portions and each of the multiple contrast element signal portions; and using a linking model that uses at least said assigned position data to link single or multiple contrast element signal portions represented in at least one of the frames to single or multiple contrast element signal portions represented in at least one other of the frames thereby to track movement of contrast elements through said region of the subject.

摘要: An optical parametric oscillator (OPO) system comprises an optical waveguide including a hollow core containing a fluid, wherein the optical waveguide is configured to receive pump light and to convert the pump light into signal light and idler light via a third order non-linear optical effect. The OPO system further comprises an optical feedback arrangement for recycling at least a portion of the signal light and/or for recycling at least a portion of the idler light in an optical cavity that includes the optical waveguide. The OPO system may be used, in particular though not exclusively, in metrology, gas and solid-state spectroscopy, laser-assisted manufacturing, semiconductor technology, biomedicine, healthcare, and scientific laboratory use.
