摘要： An electromagnetic survey method for surveying an area previously identified as potentially containing a subsea hydrocarbon reservoir, comprising obtaining first and second survey data sets with an electromagnetic source aligned end-on and broadside relative to the same or different receivers. The invention also relates to planning a survey using this method, and to analysis of survey data taken in combination allow the galvanic contribution to the signals collected at the receiver to be contrasted with the inductive effects, and the effects of signal attenuation, which are highly dependent on local properties of the rock formation, overlying water and air at the survey area. This is very important to the success of using electromagnetic surveying for identifying hydrocarbon reserves and distinguishing them from other classes of structure.

摘要： A method of electromagnetic surveying of an area of seafloor that is thought or known to contain a subterranean hydrocarbon reservoir is described. The method includes broadcasting an EM signal from a horizontal electric dipole (HED) transmitter and obtaining vertical electric dipole (VED) response data at a remote receiver in response thereto. Survey data are analysed by comparing the VED response data with background data which are not sensitive to the postulated hydrocarbon reservoir. Accordingly, differences between the VED response data and the background data allow for the identification of buried hydrocarbon reservoirs. The background data may be provided by magneto-telluric surveying, controlled source electromagnetic surveying or from direct geophysical measurement. By employing VED response data in this way, surveys may be performed in shallower water than has previously been possible since the VED detector is not sensitive to air-wave components of the EM field induced by the HED transmitter at the VED detector.
摘要翻译：描述了认为或已知含有地下油气藏的海底区域的电磁勘测方法。该方法包括从水平电偶极子（HED）发射器广播EM信号，并响应于远程接收机获得垂直电偶极子（VED）响应数据。通过比较VED响应数据和对假设的油气藏不敏感的背景数据来分析调查数据。因此，VED响应数据和背景数据之间的差异允许识别埋藏的油气藏。背景数据可以通过磁碲测量，受控源电磁测量或直接地球物理测量来提供。通过以这种方式采用VED响应数据，可以在比以前可能的浅水中进行调查，因为VED检测器对由VED检测器处的HED发射器感应的EM场的气波分量不敏感。

摘要： The system and method for real-time monitoring of a hydrocarbon reservoir (4) during extraction include an electro-magnetic source assembly (16) for transmitting a first plurality of electromagnetic fields. A plurality of seafloor antennae (30a–30d) is distributed over an area of the seafloor (8) corresponding to the reservoir (4), where each antenna (30a–30d) comprises recieves electrode array (30a–30d) adapted for receiving a second plurality of electromagnetic fields and generating signals corresponding to the detected fields. A data logging processor receives the signals over time and stores data corresponding to the signals. Different combinations of the receiver electrode are used in combination with transmitter antennae for measuring vertical, radial and/or azimuthal fields. Transmission and detection of the fields can be performed continuously or at timed intervals during hydrocarbon extraction to estimate the rate and efficiency of extraction.

摘要： A method and apparatus for determining abnormal pressure zones of a geologic formation using NMR measurements, preferably for logging-while-drilling applications. In a preferred embodiment, a normal compaction trend is constructed using NMR-derived clay bound water volume (CBW) content for non-consolidated subsurface formations or bulk volume irreducible (BVI) and CBW for consolidated formations versus depth. Deviations from this normal compaction trend are used to indicate the presence of shale sections with higher porosity that directly corresponds to an overpressured top seal or transitional zone.

摘要： Disclosed are a method and system for developing customized bound water transformations to obtain accurate determinations of non-producible water from nuclear magnetic resonance (NMR) logs. The approaches of this invention can be applied for in situ calibration where laboratory NMR measurements may not be possible or practical. In particular, a transformation model directly linking BVI and capillary pressure is developed by calibrating NMR derived BVI with the core data, the novel transformation model utilizes SBVI and/or CBVI models to directly relate NMR derived BVI and capillary pressure responses through the height of the measurement in a borehole. The derived height-based BVI transformation model is applied to the NMR log of the borehole to quantify non-producible water in the NMR log.

摘要： A casing pipe is inserted into a drilled hole reaching the inside of a confined aquifer in which groundwater is stored and flows or a position near the confined aquifer. A measuring device measures an electromagnetic field at the distal end of the casing pipe. An analyzing device analyzes data concerning the electromagnetic field measured by the measuring device to sense motion of ground pore water, thereby predicting rapid motion in the earth's crust, such as a volcanic eruption, an earthquake, a landslide and ground collapse. The casing pipe is an electrically conductive pipe having a non-magnetic screen portion formed at the distal end thereof so that recycling groundwater passes through the screen portion. The measuring device includes an electromagnetic field sensor placed in the screen portion and the conductive casing pipe as an electrode for measuring an electric potential relative to an electric potential at the earth's surface detected with a reference electrode.
