A wellhead shelter includes a catch pan including at least two sections defining therebetween an opening, the opening being positionable about the wellhead when the pan sections are secured together; and an upwardly extending cover including at least two members each being connectable adjacent their lower ends to the pan and connectable together for covering at least a part of the wellhead.
Claims (18)
1. A wellhead shelter comprising: a catch pan including at least two sections defining therebetween an opening, the opening being positionable about the wellhead when the at least two pan sections are secured together; and an upwardly extending cover including at least two members each being connectable adjacent their lower ends to the pan and connectable together for covering at least a part of the wellhead.
2. The wellhead shelter of claim 1 wherein at least one of the at least two members is pivotally connected to the pan to permit pivotal movement of the at least one member between a position laid adjacent the pan to a position upwardly extending from the pan.
3. The wellhead shelter of claim 2 wherein the at least one of the at least two members is pivotally connected via a hinged connected positioned within the shelter.
4. The wellhead shelter of claim 1 wherein the at least two members are pivotally connected to the pan to operate in an upwardly opening clam-shell-type configuration.
5. The wellhead shelter of claim 1 further comprising interfacing surfaces between the at least two members, which come together when the at least two members are connected together for covering at least a part of the wellhead.
6. The wellhead shelter of claim 5 further comprising an extension member on at least one of the at least two members to overlap the interfacing surfaces.
7. The wellhead shelter of claim 5 further comprising alignable notches on the interfacing surfaces to accommodate wellhead extensions therein.
8. The wellhead shelter of claim 7 further comprising a sealing material lining the notches.
9. The wellhead shelter of claim 1 wherein the pan includes an upper edge and at least one of the at least two members includes a lower edge and the lower edge of the at least one member includes a flange to extend down and overlap the pan upper edge.
10. The wellhead shelter of claim 9 wherein the flange is part of a U-shaped channel formed along the lower edge of the at least one member.
11. The wellhead shelter of claim 1 wherein the at least two members include a layer of insulation.
12. The wellhead shelter of claim 1 further comprising an inspection door and opening through at least one of the at least two members.
13. The wellhead shelter of claim 1 wherein the catch pan sections include a double layer construction.
14. The wellhead shelter of claim 1 wherein the catch pan sections each include side walls and a floor, at least one of the side walls forming an interfacing wall to be secured together with the other catch pan sections to assemble the catch pan and an indentation formed in the interfacing wall to align with the indentations of other catch pan sections to form the opening.
15. The wellhead shelter of claim 14 further comprising a C-channel mounted over upper edges of the interfacing sides.
16. The wellhead shelter of claim 1 wherein the catch pan includes a pump jack side and an opposite side and the distance from the opening to the opposite side is greater than the distance from the opening to the pump jack side.
17. The wellhead shelter of claim 1 wherein the catch pan includes a first end positionable under the pressure gauge side of the wellhead and an opposite end positionable under the flow line side of the wellhead and the distance from the opening to the opposite end is greater than the distance from the opening to the first end.
18. The wellhead shelter of claim 1 further comprising a sizing ring to seal any gap between the opening and the wellhead.
