| 20120026314 | METHODS OF ELECTROMAGNETIC MIGRATION IMAGING OF GEOLOGIC FORMATION - Methods and systems for imaging-while-drilling and look-ahead imaging of a geological formation using a borehole devices measuring multi-component vector and/or tensor logging data. An electromagnetic field transmitter generates an electromagnetic field. Electromagnetic receivers measure the response from the geological formation around the borehole and ahead of the device at various receiving positions. A central processing unit may compute a migration field by simulating the replacement of the receivers with conceptual transmitters, calculate an integrated sensitivity of the recorded electromagnetic field data, compute a reference field, and calculate a cross power spectra of the reference and the migration fields or cross correlation functions between the reference and the migration fields. A spatial weighting of the cross power spectra or cross correlation functions produces a numerical reconstruction of directional images and look-ahead images of the conductivity distribution around the borehole and/or ahead of the device located within the borehole. | 02-02-2012 |
| 20110144472 | METHODS OF GRAVITY AND/OR MAGNETIC HOLOGRAPHIC IMAGING USING VECTOR AND/OR TENSOR DATA - A method for holographic imaging an object having density and/or magnetization is described, the object being located in an examined medium using potential field data including but not limited to gravity and/or magnetic total field and/or vector and/or tensor data. The potential field sensors may measure the gravity and/or magnetic total field and/or vector and/or tensor data at least one receiving position with respect to the examined medium. At least one component of the measured potential field in at least one receiver location (potential field data) may be used as at least one artificial source of the potential field data. Artificial sources may produce a back-propagating (migration) field. An integrated sensitivity of the potential field data to density and/or magnetization perturbation may be calculated. A spatial weighting of at least one of the back-scattering (migration) fields may form a potential field holographic image. At least one desired property of the medium, such as density and/or magnetization, may be derived from this holographic image. | 06-16-2011 |
| 20100194394 | SYSTEMS AND METHODS FOR REMOTE ELECTROMAGNETIC EXPLORATION FOR MINERAL AND ENERGY RESOURCES - A method for measuring the resistivity of geologic formations is described. An electromagnetic field may be generated using at least one stationary long-range transmitter. The frequency of the electromagnetic field may be between and/or including the ULF/ELF range. At least one component of the electromagnetic field may be measured by land, marine, and/or airborne receiver. A conductivity distribution may be determined based on the at least one measured component. The determined conductivity distribution may be correlated with geological formations and/or hydrocarbon deposits. | 08-05-2010 |
