摘要： Various embodiments include apparatus and methods to detect and locate conductive bodies and/or provide steam-assisted gravity drainage (SAGD) steering operation. Tools can be configured with receiving sensors (310) arranged to cancel substantially a primary signal associated with a probe signal without rotating the receiving sensors to cancel the primary signal and to capture a secondary signal generated from a conductive body (301) below the earth's surface. Additional apparatus, systems, and methods are disclosed.

摘要： Parallel drilling systems and methods suitable for drilling wells for steam-assisted gravity drainage (SAGD). In some method embodiments, a tilted-antenna tool gathers azimuthally-sensitive electromagnetic signal measurements. Such measurements enable accurate measurement of inter-well distance and direction, thereby providing, the necessary information for drilling accurately-spaced wells having reduced vulnerability to “short-circuits” that inhibit effective reservoir exploitation. In some other method embodiments, a tilted-antenna tool transmits azimuthally non-uniform signals as it rotates. The attenuation and azimuthal variation detected by one or more receivers enables accurate direction and distance determination. The transmitter and receiver antennas can in some cases be combined into a single tool, while in other cases the transmitters and receivers are placed in separate wells to increase detection range.

摘要： Methods and systems that compensate for magnetic interference in azimuthal tool measurements. At least some method embodiments include a downhole logging method that includes taking measurements as a function of orientation from inside a borehole. The measurements are associated with different azimuthal bins, and an azimuthal direction is determined for each azimuthal bin. Because the tool rotates at a constant rate, the relative number of measurements associated which the different bins can be used to measure the effective sizes of the different bins and to redetermine the effective angles of the bins in the presence of magnetic interference. The tool measurements may include, but are not limited to, formation resistivity, magnetic field, and formation density.

摘要： A disclosed fracture characterization method includes: collecting three-dimensional resistivity measurements of a volume surrounding an open borehole; analyzing the measurements to determine parameters describing fractures in the volume; and providing a report to a user based at least in part on said parameters. A fluid with a contrasting resistivity is employed to make the fractures detectable by a directional electromagnetic logging tool in the borehole. Illustrative parameters include fracture direction, height, extent, length, and thickness. The resistivity measurements can be augmented using a borehole wall image logging tool. Also disclosed are fracturing methods that include: positioning a directional electromagnetic logging tool proximate to a formation; fracturing the formation; monitoring fracture progression with said tool; and halting the fracturing when measurements by said tool indicate that a predetermined set of criteria have been satisfied.

摘要： Disclosed herein are electromagnetic resistivity logging systems and methods that employ magnetic dipole antennas embedded in wall-contacting surfaces. In some embodiments, the antennas are pot-core or ferrite-rod antennas. Prototypes of electromagnetic resistivity logging tools having such antennas exhibit good resistivity logging performance in both water-based and oil-based borehole fluids, indicating that this architecture may yield a logging tool that is suitable for use with borehole fluids of all types. Moreover, the tool offers good spatial resolution, enabling the creation of formation resistivity images for the borehole walls.
