A method is provided for processing resistivity data associated with a formation. The resistivity data relating to the formation proximate to a wellbore is obtained. The resistivity data is divided in to a preconfigured plurality of bins, wherein the resistivity data associated with each bin is measured in the direction or the range of directions corresponding to the bin. A rose diagram is generated for a portion of the resistivity data associated with a measured depth of the wellbore. The rose diagram includes a circle divided into a plurality of sectors, wherein each sector corresponds to a bin. Each sector visually represents the resistivity data relating to the formation in a direction or range of directions from the wellbore corresponding to the bin. The generated rose diagram is rendered for display. The rendered rose diagram displays the resistivity data in a cross-section perpendicular to the wellbore at the corresponding measured depth.

The disclosure presents processes that utilize collected resistivity data, for example, from an ultra-deep resistivity tool located downhole a borehole. In some aspects, each slice of resistivity data can generate multiple distribution curves that can be overlaid offset resistivity logs. In some aspects, an analysis can be performed to identify trends in the distribution curves that can be used to identify approximate locations of subterranean formation surfaces, shoulder beds, obstacles, proximate boreholes, and other borehole and geological characteristics. As the number of distribution curves generated increase, the confidence in the analysis also increases. In some aspects, the number of distribution curves can be twenty, one hundred, one hundred and one, or other counts of distribution curves. In some aspects, the resistivity data can be used to generate two or more synchronized view perspectives of a specific location along the borehole, where each view perspective uses the same focus area.

A method is provided for processing sensor data associated with a formation. The sensor data is obtained and divided into a plurality of voxels in a three-dimensional environment. Each voxel corresponds to a location in the formation surrounding a wellbore. A selection of a first point in the three-dimensional environment corresponding to a first position along the wellbore is received. A selection of a first two-dimensional shape intersecting the first point is received. A selection of a second point corresponding to a second position different from the first position along the wellbore is received. A three-dimensional volume containing a subset of the plurality of voxels of sensor data is generated. The three-dimensional volume is bound at least by the first point and the first two-dimensional shape at a first end and by the second point at a second end. The generated three-dimensional volume is rendered for output on a display.

The disclosure presents processes to generate look ahead data to guide borehole operations, such as drilling operations. The processes can array collected resistivity data around a representation of an active borehole. The array can be in various patterns, such as an interleaved helix pattern. Each slice of data from the collected resistivity data can be positioned and oriented corresponding to the central point depth parameter for each slice of data. A selection of one or more card views can be enabled to display details of the collected resistivity data corresponding to the selected slice of data. An analysis of the resistivity data can generate an identification of a boundary, such as an object or a subterranean formation change, in the subterranean formation look ahead portion of the active borehole. The boundary identification can be used as inputs to a borehole operation plan or to a geo-steering system.
