摘要： A system and method for the geomechanical steering of the orientation of a wellbore is disclosed. In one embodiment, any available a priori data regarding the stress characteristics of a region of interest are used to develop a preliminary stress model for the region. A geosteered drilling operation is thereafter commenced, with the trajectory being steered in a direction relative to the stress model of the region. While drilling, real-time data is obtained from conventional down-hole instrumentation. The real-time data is used to refine the stress model for the region, such that the trajectory can be guided on an ongoing basis to achieve an optimal relationship with the measured stress characteristics of the region.

摘要： A system, method and computer-readable medium for developing an earth formation is disclosed. A tool conveyed in a borehole induces a stress in the earth formation proximate a borehole. A sensor assembly obtains a measurement of a physical property of the borehole at a plurality of azimuthal locations in the borehole. The values of the physical property are indicative of the induced stress in the formation. A processor forms an image of the borehole using the obtained measurements of the physical property, estimates an azimuthal variation with borehole depth of the induced stress in the formation from the formed image, and alters an operational parameter of a device for developing the earth formation using the estimated azimuthal variation with depth of the induced stress in the formation.

The model may be used to provide a caliper measurement where acoustic caliper data are unreliable.

摘要： A data compression technique for MWD applications uses feature detection, extraction, followed by image compression for only the region(s) of interest. The detection approach processes data in real time. It triggers on the start and end of a feature without processing any further features. This provides feature detection with zero latency. Compressing only the region of interest provides data compression with both higher resolution and higher compression ratio.

摘要： The present invention provides a method and apparatus for logging an earth formation and acquiring subsurface information wherein a logging tool is conveyed in borehole to obtain parameters of interest. The parameters of interest obtained may be density, acoustic, magnetic or electrical values as known in the art. The parameters of interest are acquired with a plurality of sensors. For time based image data, the time separation values between signals acquired from separate sensors for individual subsurface features are determined. The time separation values may be determined using correlation or other methods illustrated herein or as known in the art. Using known sensor spatial separations and time separation values a drill rate is determined and an incremental depth for the subsurface feature is defined. The geometries of subsurface features in incremental depth relative to the well bore may be accurately determined, including extremely accurate dip and azimuth structural information relative to the borehole.
