摘要: Systems and methods of detecting marine seismic survey parameters are provided. A data processing system can obtain seismic data from seismic data acquisition units disposed on a seabed responsive to an acoustic signal propagated from an acoustic source through a water column. The data processing system can determine from the seismic data, a direct arrival time for the acoustic signal at each of the plurality of seismic data acquisition units, and can obtain an estimated depth value of each of the plurality of seismic data acquisition units and an estimated water column transit velocity of the acoustic signal. The data processing system can apply a depth model and a water column transit velocity model to the estimated depth value and to the estimated water column transit velocity determine an updated depth value and an updated water column transit velocity for each of the plurality of seismic data acquisition units.

摘要: Current supplied to electrical submersible pumps in wells is monitored, and signal processing based on wavelet analysis and phase diagram analysis is performed on the data obtained from monitoring. An incipient malfunction of the electrical submersible pump, such as one due to scale build-up in and around the pump, can be detected at an early stage.

摘要: Some examples of monitoring hydrocarbon reservoirs using induced polarization effect includes inducing polarization in a subterranean zone using an induced polarization fluid. The subterranean zone includes first formations and second formations. A quantity of hydrocarbons in the first formations is greater than quantity of hydrocarbons in the second formations. The induced polarization data is obtained from the subterranean zone. A portion of the induced polarization data from the first formations is different from a portion of the induced polarization data from the second formations. The second formations in the subterranean zone are identified based on the obtained induced polarization data

摘要: The invention relates to a system for monitoring a substratum (1) with regard to damage and/or for protecting a substratum (1) from damage. The system comprises: an electrolytically active layer (4), which has a moisture-dependent electrical resistance; at least one electrode pair, the spaced-apart electrodes (3a, 3b) of which are connected to each other by means of the electrolytically active layer (4); and a measuring device, by means of which a property, in particular an electrical quantity of the electrolytically active layer (4) or of the electrodes (3a, 3b), can be measured by using electrodes (3a, 3b) of at least one electrode pair, in particular of each electrode pair, and/or a control device, by means of which a voltage can be applied to the electrodes (3a, 3b) of at least one electrode pair, in particular of each electrode pair. At least one of the electrodes (3a, 3b) of the at least one electrode pair is designed as a planar electrode in the electrolytically active layer (4), in particular the plane of said at least one electrode is oriented parallel to the surface of the substratum (1). The invention further relates to a method for producing a system for monitoring and/or for protecting a substratum, to a method for monitoring a substratum with regard to damage, and to a method for protecting a substratum from damage, in particular moisture damage and/or damage as a result of the penetration of harmful substances.

摘要: A kit for non-invasively determining the presence of non-electrically conductive plumbing in a residence includes an electrical resistance measuring device having a main body and a resistance measuring circuit disposed therein and a display for indicating the value of the resistance measured by the resistance measuring circuit. The kit further includes at least two test probes which are in electrical communication with the resistance measuring circuit of the device. In a method for determining the presence of non-electrically conductive plumbing in the residence using the kit, one of the test probes is connected to an exposed portion of electrically conductive piping and the other is connected to a grounded conductor. When a low measured resistance is observed, as indicated by the device, the operator determines that the residence does not have non-electrically conductive plumbing. When a high measured resistance is observed, the operator determines that non-electrically conductive plumbing is present.

摘要: An apparatus that includes two non-coinciding arrangements disposed in an two axes Cartesian coordinate system such that each arrangement having a non-zero projection on a respective axis from among the two axes. Each one of the arrangements includes a pair of oppositely directed, spaced apart, co-axial radiating-capable elements, each of the elements being hollow with internal space, and being slotted throughout its entire extent. A first circuitry coupled to the arrangement and being configured to sense an electric field projection along the axis and to convey it to a first feeding terminal. A second circuitry coupled to a slot of the arrangement and being configured to sense a magnetic field's projection along said axis and to convey it to a first feeding terminal.
