摘要： An acoustic source system for permanent monitoring of a reservoir comprises at least one acoustic source (130) configured for long-term deployment on a solid surface (10) at the reservoir. The system also comprises a combined power source supplying electrical power to the acoustic source (130) and a sensor array (100) monitoring the reservoir, and a combined communication system for the acoustic source (130) and the sensor array (100). The acoustic source (130) is individually addressable through the combined communication system. Time is of little concern, so that the acoustic source (130) can be charged through the infrastructure (102, 105). The existing communication system is extended with the addresses of the acoustic sources, and can be used to control the acoustic source, including triggering a shot. Offshore and-land-based applications are described.

摘要： A system (100) for monitoring a subterranean structure comprises an array (10) with n acoustic sensors capable of detecting P-waves and/or S-waves from the subterranean structure and a central controller (120) for receiving a signal (X) from the sensors. The system further comprises a lookup table (20) comprising a pre-computed travel time curve (24) expressed as relative arrival times of a signal from a location (L m ) to each of the sensors (1-n); a comparison unit for comparing the received signal (X) with the pre-computed travel time curve (24), and means for raising an alarm if the received signal (X) matches the precomputed travel time curve (24). Preferably, the alarm is raised if a computed semblance value (26, 27) exceeds a predefined threshold. The system may monitor several locations (L m ) in parallel using a fraction of the computer resources and time required by prior art techniques.

摘要： A method (300) for determining a position of a drill bit (204) in a formation during drilling, comprising the steps of: a) For at least two wave modes (P,S), recording (310) a separate observed pattern of observations from a seismic array (206) on a land surface or a seafloor; b) Computing (320) a predicted pattern for each wave mode (P, S); c) Comparing (330) the observed and predicted patterns for each wave mode (P, S) to obtain first estimates of the drill bit position; d) Determining (340) an improved estimate from the first estimates.

摘要： A method for measuring subsidence and/or uprise on a field, comprises the steps of: deploying at least one cable (100) on a solid surface; collecting inline tilt data from numerous tilt sensors deployed along each cable (100); and performing a statistical analysis on the tilt data to determine changes in curvature on the solid surface. Preferably, the statistical method involves computing a cumulative inline and/or cross-line tilt, whereby random errors cancel and systematic changes add. In addition, regression and/or interpolation may provide a quantitative estimate of curvature etc.

摘要： A system (1) for operating a subsea sensor field (2), comprises an automated underwater vehicle - AUV (10) and a subsea service station (13). A sensor (11, 12) in the sensor field (2) comprises a permanently installed base unit (11) and a removable control unit (12). The AUV (10) moves control units (12) to the service station (13) for charging and updating, and then back to the base units. The permanent positions of the base units (11) facilitate time-lapse surveys, and saves energy as heavy equipment may remain on the seafloor.
