| 20090243614 | SIGNAL GENERATOR FOR ELECTROMAGNETIC SURVEYING THAT PRODUCES A SIGNAL HAVING AN ANALOG CONTINUOUS WAVEFORM - To perform an electromagnetic (EM) surveying of a subterranean structure, a signal generator produces a signal having an analog continuous waveform without steps in the waveform. An antenna is responsive to the signal having the analog continuous waveform to emit an EM field to produce the EM surveying of the subterranean structure. | 10-01-2009 |

| 20100019929 | COMMUNICATION SYSTEM FOR SURVEY SOURCE AND RECEIVER - A method for communicating with a receiver during an electromagnetic survey. In one implementation, the method may include sending a survey signal to a subsurface region, wherein the survey signals is a first electromagnetic signal and sending a diagnostic signal to the receiver. The diagnostic signal is a second electromagnetic signal having a diagnostic message. | 01-28-2010 |

| 20080238428 | Methods of Electromagnetic Logging Using a Current Focusing Receiver - A method for determining a formation electrical property under a sea floor includes obtaining measurement data using a receiver having an impedance lower than an impedance of seawater at a measurement site; correcting the measurement data to obtain corrected data corresponding to data that would have been acquired using a receiver having an impedance matched with the impedance of the seawater; and deriving the formation property from the corrected data. | 10-02-2008 |
| 20080238429 | Receivers and Methods for Electromagnetic Measurements - A receiver for electromagnetic measurements includes a polyhedron structure having m faces, where m≧4 and m≠6: n electrodes each disposed on one face of the polyhedron structure, wherein 3≦n≦m; and at least one circuitry connected to the n electrodes for signal measurement. A method for electromagnetic measurements includes obtaining a plurality of electric current measurements using a plurality of electrodes each disposed on a surface of a polyhedron receiver, wherein the plurality of electric current measurements comprise at least three different measurements; and determining electric field components in a three dimensional space from the plurality of electric current measurements by using a number of matrices that correlate orientations of surfaces of the polyhedron receiver to a coordinate system in the three dimensional space. | 10-02-2008 |
