This disclosure presents a process to determine an alignment parameter for geosteering a wellbore undergoing drilling operations. The process can receive one or more azimuthal image log data sets, one or more geology logs, and other input parameters. The image log data sets can be transformed to better approximate the geology logs, such as transforming a 3D representation to a 2D representation and flattening out curves represented in the original image log data. The geology logs or transformed image log data can then be moved to create an approximate alignment between the other log data. The movement, which can be a sliding movement, a linear movement, a tilting movement, an angling movement, or a rotating movement, can be used to determine the determined alignment parameter or final alignment parameter. The alignment parameter can be used as input into a geosteering system for the wellbore.

Determining a geological correlation with a wellbore position

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.

Evaluation and visualization of well log data in selected three-dimensional volume

The disclosed embodiments include systems and methods to evaluate a formation dip of a formation bedding. The system includes memory configured to store a color image indicative of a log of a formation bedding. The system also includes a processor configured to execute instructions to filter colors of the color image to determine one or more cusps of the formation dip, and cross correlate a reference wave with the one or more cusps of the formation dip to match curvatures of the reference wave with the one or more cusps of the formation dip illustrated in the color image, wherein the curvatures of the reference wave are based on one or more parameters of the formation bedding. The processor is further operable to generate a wave that matches the one or more cusps of the formation dip with the reference wave, where the wave is indicative of the formation dip.

Formation dip evaluation system

The disclosed embodiments include systems and methods to evaluate formation resistivity. In one embodiment, a method to evaluate formation resistivity proximate a wellbore is provided. The methods includes receiving data indicative of resistivity measurements of a formation proximate a wellbore at different distances within a range of distances from the wellbore. The method also includes analyzing the data to determine approximate formation resistivity of the formation at different distances from the wellbore. The method further includes generating at least one curve, each indicative of an approximate formation resistivity of the formation at the different distances from the wellbore, overlaying the at least one curve on a graph indicative of the formation resistivity of the formation within the range of distances from the wellbore, and providing the at least one curve overlaid on the graph for display on a device.
