摘要： Provided are a method, a computer program product and a system, to measure characteristics of a geologic formation, such as hydrocarbon reservoirs, that employs modeling data to remove unwanted information from a signal carrying information concerning the geologic formation. This allows obtaining accurate information concerning the resistivity of geologic formations in which a borehole has been formed and encased with a conductive liner, such as a steel casing. Specifically, it was recognized that a magnetic field produced within a borehole that has been cased is substantially similar to magnetic field produced from a borehole that was not cased, i.e., the spatial distribution and orientation to the two aforementioned magnetic fields are the same, differing only by a constant related to the casing attenuation factor. The magnetic field outside of the cased borehole is reduced in amplitude by an attenuation factor associated with the liner. Thus, the magnetic field produced at a point outside of the liner is a function of the product of term for the attenuation factor of the liner, ke and a term for the response of the geologic formation, ƒ. Both terms are independent of the other. Thus, by factoring and removing information concerning the attenuation factor, ke, accurate measurements of the geologic formation may be determined.

摘要： Methods and systems are provided to determine a property of an earth formation, comprising a mobile transmitter disposed at a predetermined elevated height above a surface of the earth formation, and one or more receivers moveably disposed in a wellbore penetrating the earth formation. Electromagnetic energy is transmitted from the mobile transmitter into the formation from a plurality of locations; and at the one or more receivers a signal is measured. Using the signal received by the one or more receivers, a property of the formation, such as resistivity, can be determined and mapped.

摘要： A technique that is usable with a well includes providing a model so predict measurements that are received by receivers due to transmissions by sources based on estimated positions of the receivers relative to the sources. The estimated positions each have at least two dimensions. At least some of the receivers and the sources are located in the well. On a computer, the estimated positions are automatically refined based on a comparison of the predicted measurements and actual measurements that are obtained by the receivers.
