Abstract
This disclosure presents methods and processes to estimate a position parameter, an orientation parameter, a dip parameter, and a diameter parameter of an object or subterranean formation change proximate an active borehole. The object or formation can be an adjacent borehole. The parameters can be utilized by a geo-steering system or a well site job plan system to reduce an uncertainty surrounding or looking ahead of the active borehole to avoid a collision with the object or formation, to intercept the object or formation, or to place the active borehole in a more advantageous position. The parameters can be derived from collected component resistivity data that has been reconstructed utilizing a three-dimensional inversion algorithm. In some aspects, low resistivity data can be extracted to improve the estimating of the parameters. In some aspects, the process can be implemented in a downhole tool, in a surface system, or a combination thereof.
