Cellar Tech’s Surface Casing Hangers work in conjunction with the well cellar’s structural base plate to provide E&P companies with a product that offers benefits such as:
- Elimination of waiting on cement (WOC) time for the surface casing cement. (More info here)
- Elimination of shallow gas migration. (More info here)
- Standardization of wellhead installation geometry.
Landing Cellar Tech’s Surface Casing Hanger
Our Surface Casing Hangers install easily and can be welded to the surface casing before arriving at the well site so that no welding is done on location. In the video below a non-latching Surface Casing Hanger is used. Latching Surface Casing Hangers are landed in the same manner as non-latching models and do not require any special tools.
Other features and benefits include:
- Centers the surface casing in the conductor which is the initial step in creating standardized and repeatable well installations.
- Substantially improved surface casing cement bond and isolation.
- Available in locking or non-locking configurations. The latching mechanism anchors the surface casing and prevents upward movement if the casing becomes buoyant during cementation.
- The hanger design allows for a 1″ pipe and coupling to pass if remedial cementing or a top job is necessary.
- Many sizes available.
Surface Casing Hanger Installation
Cellar Tech’s Surface Casing Hanger can be welded to the surface casing ahead of time at our facility or in the field. Our Surface Casing Hangers weld easily to the surface casing and all welding done at Cellar Tech’s facility is inspected and certified.
Landing Ring Installation
Landing Rings can usually be lowered on to the conductor by hand and then welded. For Landing Rings that are too heavy to set on the conductor by hand Cellar Tech offers a Landing Ring Installation Tool. The Landing Ring Installation Tool grabs on to the Landing Ring and rigging may be attached to then lower our heavier Landing Rings in to place. The operation of the Landing Ring Installation tool is simple and requires no special tools.
