Abstract
Description
BACKGROUND1. Field of the DisclosureEmbodiments disclosed herein relate generally to drilling rigs. In particular, embodiments disclosed herein relate to portable drilling rig apparatuses and related methods of assembly.2. Background ArtA drilling rig is used to drill a wellbore in a formation. Drilling rigs may be large structures that house equipment used to drill water wells, oil wells, or natural gas extraction wells. Drilling rigs sample sub-surface mineral deposits, test rock, soil and groundwater physical properties, and may also be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells. Drilling rigs may be mobile equipment mounted on trucks, tracks, or trailers, or more permanent land or marine-based structures (such as oil platforms). The term “rig,” therefore, generally refers to a complex of equipment that is used to penetrate the surface of the earth's crust.Referring to FIG. 1, a conventional drilling rig 30 is shown....

Embodiment Construction
In one aspect, embodiments disclosed herein relate to portable drilling rig apparatuses and related methods of assembling the portable drilling rig.
Referring to FIG. 2, a perspective view of a portable drilling rig 100 prior to assembly is shown in accordance with embodiments of the present disclosure. The drilling rig 100 includes a base assembly 120 and a mast structure 110 configured to be installed on the base assembly 120. The base assembly 120 includes a collapsible rig floor 122, which will be described later.
Drilling rig 100 may further include a pedestal structure 130 that may be mounted on rig floor 122 and configured to link mast structure 110 and rig floor 122, as well as aid with assembly of the drilling rig 100. Pedestal structure 130 may include an upper attachment point 132 configured to be pinned to a mast pivot point 112 during assembly. Pedestal structure 130 may also include a lower pivot point 134, which is pinned to rig floor 122, about which pedestal structure...
