Abstract

An apparatus for supporting tubular goods and wellbore tools that can be used to perform down-hole operations in oil and gas wells. The support apparatus has a minimal footprint and requires minimal surface area. The support apparatus can be used to jack and remove casing and other pipe, as well as other rig-less downhole well operations.

Claims

1. A support apparatus for performing operations on a well comprising:

a) a first elongate girder member having a substantially planar upper surface;

b) a second elongate girder member having a substantially planar upper work surface, wherein said first and second elongate girder members are oriented substantially parallel to each other and define a gap therebetween, and wherein said well is disposed in said gap;

c) a lower deck, slidably disposed on said first and second elongate girder members, having a substantially planar upper work surface adapted to support personnel and an opening extending through said lower deck, wherein said opening is at least partially aligned with said gap between said first and second elongate members;

d) an upper deck having a substantially planar upper surface adapted to support personnel and an opening extending through said upper deck;

e) at least one support member connecting said upper and lower decks, wherein said upper and lower decks are oriented substantially parallel to each other and define a substantially open space there between;

f) a table member aligned with the opening of said upper deck, said table member having an opening through said table member aligned with the opening of said lower deck;

g) at least one hydraulic cylinder having an upper end and a lower end, wherein said lower end is mounted on said lower deck, said upper end is connected to said table member, and wherein extension of said at least one hydraulic cylinder raises said table member within said opening extending through said upper deck; and

h) a powered rotary disposed on said table member for applying torque to a pipe or other tubular member extending through said table, wherein said rotary does not comprise a power swivel.

2. The support apparatus of claim 1, further comprising at least one deck extension member detachably connected to said upper deck.

3. The support apparatus of claim 2, wherein said deck extension member comprises grating having a substantially planar upper surface, wherein the upper surface of said grating is substantially aligned with the upper surface of said upper deck.

4. The support apparatus of claim 1, further comprising at least one door aligned with said opening of said lower deck and hingeably connected to said lower deck.

5. The support apparatus of claim 1, further comprising at least one door aligned with said opening of said extendable table member and hingeably connected to said table member.

6. The support apparatus of claim 1, further comprising at least one elongate locking member comprising:

a) a substantially hollow sleeve member having a top and a bottom, wherein said bottom is connected to said lower deck and said top is open;

b) an elongate inner member, telescopically received within said sleeve member; and

c) a plurality of transverse bores extending through said elongate inner member.
