TECHNICAL FIELD

The present disclosure relates generally to tools usable in drilling a wellbore for extracting hydrocarbons and, more particularly (although not necessarily exclusively), to visualizing look-ahead, ultra-deep resistivity measurements downhole.

BACKGROUND

A well system (e.g., oil or gas) may include a wellbore drilled through a subterranean formation. The subterranean formation may include a rock matrix permeated by oil or gas that is to be extracted using the well system. During the drilling operation, a drill bit may approach or pass through various rock formation boundaries in the rock matrix. Logging positions of the drill bit and the various rock formation boundaries during the drilling operation assists in identifying the location of a particular boundary.

Visualizing formation positions and boundaries while drilling into the earth provides information to surface controllers and personnel. Providing downhole information to a surface computing system improves safety, efficiency, and reliability of wellbore drilling. Visualization of boundary locations that are deeper and near the path of the drill bit (e.g., near-vertical drilling) is difficult because of the geometry of the sensor equipment and formats of presentation that lack the precision necessary.
