Abstract: A deployable electrical contact device is provided that includes a body portion and a mounting arrangement. The mounting arrangement is controllably deployable from the body portion. The mounting arrangement is configured to retain the device at a position at a metallic well structure by mechanically engaging with a wall surface of the metallic well structure. The mounting arrangement includes electrically conductive pads configured to provide electrical continuity between the engaged metallic well structure and the mounting arrangement. The device is configured such that when deployed an electrical signal path between one or more of the conductive pads and the body portion is established to provide electrical continuity between the metallic well structure and the body portion.

Abstract: A method of establishing fluid communication between a well pair in an oil-sand reservoir, where dilatable oil sands in the reservoir form a barrier to fluid communication between the well pair. Steam or water is circulated within at least one well to a region of the oil sands adjacent to the well. The steam or water pressure is increased to a dilation pressure sufficient to dilate the oil sands in the region. While circulating steam or water within the well at a substantially steady state, the steam or water pressure is maintained at a level sufficient to enlarge the dilated region, until detection of a signal indicative of fluid communication between the well pair. The rates and pressures of steam or water injection and production may be monitored and adjusted to vary a bottom-hole pressure in the well.

Abstract: A sensor assembly is provided for measuring moisture content of concrete. The sensor assembly includes a sensor housing that is received within an opening in the concrete. The sensor housing includes an internal bore. The sensor housing is length adjustable so as to match a length of the opening. The sensor assembly further includes a moisture sensor received within the internal bore of the sensor housing. The sensor measure the moisture content of the concrete.

Abstract: A moisture meter detects one or more conditions within an environment. The moisture meter includes a housing and one or more detection pins structurally supported by the housing. The detection pins being can measure moisture. The moisture meter further includes a sensing probe structurally supported by the housing. The sensing, probe being can measure humidity within the environment. Operation of one of the one or more detection pins and the sensing probe does not interfere with operation of the other of the one or more detection pins and the sensing probe.

Abstract: A method of establishing fluid communication between a well pair in an oil-sand reservoir is provided, where dilatable oil sands in the reservoir form a barrier to fluid communication between the well pair. Steam or water is circulated within at least one well to apply a steam or water pressure to a region of the oil sands adjacent to the well. The steam or water pressure is increased to a dilation pressure sufficient to dilate the oil sands in the region. While circulating steam or water within the well at a substantially steady state, the steam or water pressure is maintained at a level sufficient to enlarge the dilated region, until detection of a signal indicative of fluid communication between the well pair. The rates of steam or water injection and production may be monitored and adjusted, and the steam or water pressure may be controlled by adjusting the rate of steam or water injection or production to vary a bottom-hole pressure in the well.
