Borehole shape estimation

A computer system comprising:

• a processor:
• a memory coupled to the processor, wherein the memory stores programmable instructions, that when executed by the processor, cause the processor to:
• receive data points associated with a standoff measurement for a borehole, each data point including a radial distance value and an azimuthal value corresponding to the radial distance value;
• determine point-to-point angles for the data points based on at least the azimuthal value associated with each data point, each point-to-point angle spanning between two adjacent data points;
• select a geometric shape from a plurality of geometric shapes to fit to the data points based on the point-to-point angles, the plurality of geometric shapes including a circle and an ellipse;
• and
• estimate a shape of the borehole at a location of the standoff measurement based on the selected geometric shape.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to:

• receive data points associated with a standoff measurement for a borehole, each data point including a radial distance value and an azimuthal value corresponding to the radial distance value;
• determine point-to-point angles for the data points based on at least the azimuthal value associated with each data point, each point-to-point angle spanning between two adjacent data points;
• select a geometric shape from a plurality of geometric shapes to fit to the data points based on the point-to-point angles, the plurality of geometric shapes including a circle and an ellipse;
• and
• estimate a shape of the borehole at a location of the standoff measurement based on the selected geometric shape.
