| Number | Title | Issue Date |
| 7031839 | Multi-frequency focusing for MWD resistivity tools An induction logging tool is used on a MWD bottom hole assembly. Due to the finite, nonzero, conductivity of the mandrel, conventional multi frequency focusing (MFF) does not work. A correction is made to the induction logging data to give measurements simulating a ... | 04/18/2006 |
| 6975120 | Measurement of subterranean lithology using electromagnetic energy The invention subject of this application pertains to a method and apparatus for measuring the subterranean lithology using electromagnetic energy. The invention is applicable to the measurement from within uncased boreholes, i.e., and open-holes. The present invent... | 12/13/2005 |
| 6484133 | Sensor response rate accelerator An apparatus and method for sensor signal prediction and for improving sensor signal response time, is disclosed. An adaptive filter or an artificial neural network is utilized to provide predictive sensor signal output and is further used to reduce senso... | 11/19/2002 |
| 4701712 | Thermoregulated magnetic susceptibility sensor assembly A thermoregulated magnetic susceptibility sensor assembly for well-logging or the like is disclosed. The assembly includes a sensing solenoid and a non-metallic container for the sensing solenoid. Located in the container and spaced from the sensing solen... | 10/20/1987 |
| 4646025 | Magnetic probe exploration device for determining residual fossil magnetization of well hole rocks Apparatus for continuously recording, as a function of the depth, the residual magnetization of the rocks through which a well hole passes, comprising, on the one hand, a measurement probe which contains means for measuring the magnetic susceptibility and... | 02/24/1987 |
| 4507613 | Method for identifying non-magnetic minerals in earth formations utilizing magnetic susceptibility measurements A magnetic susceptibility log is run through an earth formation to identify the presence of any select non-magnetic minerals in association with magnetic minerals. The select non-magnetic mineral is identified as being present when the magnetic susceptibi... | 03/26/1985 |
| 4277750 | Induction probe for the measurement of magnetic susceptibility The probe comprises two inductance windings mounted in opposition and conted to an a.c. generator, a measurement winding placed at right angles between the two inductance windings and a measurement voltage detector. A compensation winding is placed coaxi... | 07/07/1981 |
