摘要： A method for three dimensional visualization and manipulation of downhole data. A measured signal is received a downhole environment and a three dimensional virtualization of the measured signal is generated. A stereographic viewer displays the three dimensional virtualization of the measured signal. The three dimensional virtualization can be manipulated in response to an input from a user, thereby creating a manipulated three dimensional virtualization. The stereographic viewer can display the manipulated three dimensional virtualization.

摘要： The disclosed embodiments include downhole electromagnetic reservoir monitors, and systems and methods to monitor downhole reservoirs. In one embodiment, the electromagnetic reservoir monitor includes a galvanic transmitter deployed proximate a wellbore casing and having a source electrode and a return electrode, where a current flowing from the source electrode, through a formation, to the return electrode is altered by a fluid reservoir of the formation, and where an altered component of the current induces a secondary magnetic field. The electromagnetic reservoir monitor also includes a magnetic receiver having a tilted coil deployed proximate the wellbore casing, the tilted coil having an orientation relative to a cross sectional plane normal to a longitudinal axis of the wellbore casing, and the tilted coil operable to detect a component of the secondary magnetic field, where the secondary magnetic field is indicative of at least one property of the fluid reservoir.

摘要： A borehole resistivity distribution system includes a cable having an array of transmitters along a shared conductive loop. Each of the transmitters is coupled to a corresponding frequency-dependent material or device. An application of a first drive signal to the cable excites the transmitters, to obtain a first measurement, the first drive signal having a first frequency and a first amplitude. An application of a second drive signal to the cable excites the transmitters, to obtain a second measurement, the second drive signal having a second frequency and a second amplitude. At least the first frequency is different from the second frequency, or the first amplitude is different from the second amplitude. The system further includes a processor coupled to receive the first and second measurements, to derive, based at least in part on the measurements, a resistivity distribution around a borehole.
