Abstract
An apparatus and method of automatically altering proposed sliding instructions to comply with operating parameters is described. The method includes determining, by a surface steerable system (“SSS”) and based on drilling operation information, a location of a BHA; determining, by the SSS and using the location of the BHA, a projected location of the BHA at a projected distance; determining if the projected location is within a location-tolerance window (“LTW”) associated with the projected distance; creating, in response to the projected location not being within the LTW, proposed steering instructions that result in a proposed, projected BHA location being within the LTW that is associated with the projected distance; determining whether the proposed instructions comply with the operating parameters comprising a maximum slide distance; and altering, by the SSS, when the proposed steering instructions do not comply with the operating parameters, the proposed steering instructions to comply with operating parameters.
