Abstract

A method includes assembling a telescoping substructure box having first and second substructure boxes in a collapsed configuration by nesting at least a portion of the first substructure box inside of a substantially open interior space defined by a plurality of structural elements that comprise the second substructure box. The assembled telescoping substructure box is transported to a drilling site and telescopically raised from the collapsed transportation configuration to a raised operating configuration for performing drilling operations on a wellbore location of the drilling site by telescopically raising one of the first and second substructure boxes relative to the other one of the first and second substructure boxes. A drilling mast is coupled to and raised above the telescoping substructure box, and drilling operations are performed on the wellbore location with the raised drilling mast.
