Abstract: Methods and systems are provided for monitoring subsurface steam chamber development in a thermal hydrocarbon recovery operation, which employ a fiber optic cable in a horizontal wellbore beneath the steam chamber as part of a distributed acoustic sensing technique in which the cable receives attenuated sound waves passing through the steam chamber and transmits a signal corresponding to the attenuated sound waves and unattenuated sound waves for subsequent signal processing.

Abstract: Methods and systems are provided for optimizing bitumen production from a plurality of wells employing steam-based recovery techniques such as SAGD, using hyperspectral imaging of produced emulsion samples to estimate total bitumen content at each well as a means of determining steam injection adjustment to enhance production.

Abstract: A capsule includes a cup-like capsule body with a circumferential side wall, a transverse base wall at a first end of the side wall, and a radially outwardly protruding flange encircling the side wall at its second end, and a multi-layered sealing ring lying against the flange while encircling the side wall. The sealing ring includes a compressible layer of fibrous and/or cellulose and/or paper material and an outer shielding layer of a liquid-impermeable material, where the shielding layer is provided on an outwardly directed external surface of the sealing ring and where the shielding layer is configured for shielding the inner compressible layer of fibrous and/or cellulose and/or paper material against pressurized liquid during beverage production.

Abstract: A capsule for use in an extraction machine has a frustoconical side wall, a transverse base closing one end of the side wall, an open mouth at the end remote from the base and a peripheral flange encircling the open mouth. A section of the side wall of the capsule close to the flange is thicker than the remainder of the side wall.

Abstract: A capsule for containing ground coffee is disclosed, the capsule comprising a frustoconical side wall of truncated conical form which is closed at its narrower end by a base and which has at the wider end a flange which encircles the side wall and extends radially outwardly. The flange has a first surface to which a foil is secured to close the capsule and a further surface which faces the pressing sleeve of the extraction machine when the capsule is placed in the machine prior to extraction taking place. A grid pattern of intersecting sealing ribs (90, 92, 96, 98) is provided on the further surface which ribs stand proud of the go further surface.
