Portable drilling rig apparatus and assembly method

Abstract

A portable drilling rig apparatus includes a rig floor having a pedestal structure thereon, the pedestal structure comprising a lower pivot point and a lower attachment point and wherein the pedestal structure is configured to be rotated to a vertical position about the lower pivot point. The drilling rig further includes a mast structure having a mast pivot point at a lower end of the mast structure wherein the mast pivot point is configured to be pinned to an upper pivot point of the pedestal structure.

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....

AI Technical Summary

Problems solved by technology

Drilling rigs may add considerable cost to the overall costs of extracting oil or natural gas from underground reservoirs.

This may be due to large equipment needed to erect certain drilling rigs or the difficulty of erecting certain drilling rigs in remote locations where it may be more costly to transport the drilling rig.

Also, certain oil and natural gas wells may have a relatively limited well life, i.e., the well has only a limited amount of gas or oil capable of being extracted.
