摘要： Offshore electromagnetic (EM) reservoir monitoring systems and methods, including a system with a light source producing a light beam and an EM sensor array deployed at the bottom of a body of water and above one or more subsea regions of interest, the array coupled to the light source with an optical fiber. An EM sensor modulates the interrogation light beam in response to an EM signal induced into the subsea formation by an EM source. The system further includes a processor controlling the light source, processing modulated light received from the array, and collecting data with the array to produce EM surveys, each EM survey based on data sets collected at different times. The EM sensor is physically isolated from a surrounding subsea environment. The surveys are combined to produce a time lapse earth model of the regions of interest.

摘要： A ranging system calculates the distance, direction and orientation of a target well through rotationally invariant analysis of triaxial electric and magnetic field measurements from a bottom hole assembly (“BHA”) having electromagnetic sensors. The triaxial electric and magnetic field sensors can be deployed in any downhole device without explicitly needing to process or retrieve rotational information about the downhole BHA or wireline device. Also, the distance, direction and orientation of the target well can be retrieved from a single measurement position.

摘要： A disclosed electromagnetic (EM) interferometry system includes a first EM field sensor at a first position in a downhole environment. The system also includes a second EM field sensor at a second position in the downhole environment. The system also includes a processing unit that receives a first EM field measurement from the first EM field sensor and a second EM field measurement from the second EM field sensor. The processing unit derives a response of the first EM field sensor to a virtual EM field source at the second position by cross-correlating the first EM field measurement with the second EM field measurement. The processing unit also performs an inversion process based at least in part on the derived response to obtain a model of subsurface formation properties.

摘要： Illustrative permanent electromagnetic (EM) monitoring systems and methods have a casing string positioned inside a borehole and equipped with one or more EM transducer modules having a layer of soft magnetic material that substantially encircles the casing string to amplify a signal response of a magnetic field transmitting and/or sensing element. The layer preferably has an axial dimension at least twice an axial dimension of the magnetic field sensing element, with a relative permeability at least twice that of the casing material. The magnetic field transmitting element can be a coil. The magnetic field sensing element can be a coil or a piezoelectric or magnetostrictive element that applies stress to an optical fiber. A well interface system communicates with the one or more EM transducer modules to transmit and/or collect EM signals over time. Additional casing strings may be provided in other nearby boreholes to enable tomographic mapping and monitoring of fluid interfaces in the reservoir.
