Generating Synthetic Borehole Image Logs

A system for generating borehole image logs, the system comprising:

• at least one processor;
• and
• a memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
• logging rate of penetration (ROP) data, resistivity data, and gamma ray data while drilling a borehole in a subsurface formation to generate logged data;
• determining an effective dip angle of the subsurface formation along the borehole;
• generating a depth shift table based on the effective dip angle and a well deviation angle, the well deviation angle being between the borehole and a vertical reference;
• generating datasets based on the ROP data, resistivity data, and gamma ray data, the generated datasets having higher sampling rates than the logged data;
• generating synthetic borehole images based on the generated datasets and the depth shift table;
• orienting the synthetic borehole images with respect to a reference point of the borehole.

One or more non-transitory machine-readable storage devices storing instructions for generating synthetic borehole image logs, the instructions being executable by one or more processors, to cause performance of operations comprising:

• logging rate of penetration (ROP) data, resistivity data, and gamma ray data while drilling a borehole in a subsurface formation to generate logged data;
• determining an effective dip angle of the subsurface formation along the borehole;
• generating a depth shift table based on the effective dip angle and a well deviation angle, the well deviation angle being between the borehole and a vertical reference;
• generating datasets based on the ROP data, resistivity data, and gamma ray data, the generated datasets having higher sampling rates than the logged data;
• generating synthetic borehole images based on the generated datasets and the depth shift table;
• orienting the synthetic borehole images with respect to a reference point of the borehole.
