1. A method for using one or more planned markers with a drilling plan, comprising:

  • using, by a computer system, a first log file of a first well in order to identify and store one or more markings that have a name, a true vertical depth (TVD) and a waveform;

    creating, by the computer system, one or more planned markers for a second well, where each of the one or more planned markers corresponds to one of the identified and stored markings;

    assigning, by the computer system, an estimated TVD and uncertainty range value to each of the one or more planned markers; and

    storing, by the computer system, each of the one or more planned markers with the assigned estimated TVD and uncertainty range value.
