Compact wellheads allow considerable savings of valuable time and money in the installation of equipment.
They may be of the two-stage or three-stage type heads. The two-stage heads can hang either two strings of casing or one string of casing and one of tubing. The three-stage heads can hang either three strings of casing or two strings of casing and one of tubing. They house either fluted mandrel type casing hangers with flow channels for circulation or slip type hangers for contingencies.
- Reduce installation height.
- Minimize the need to lift the BOP during drilling or completion.
- Easy intervention in case de casing gets caught .
- Possibility of remove the tubing head, allowing to cut the casing conventionally.
