Abstract
A diverter system is configured to control a direction of drilling fluid or gas from a well bore to a surface platform. The diverter system includes a housing configured to receive a casing from a well bore, at least one outlet configured to direct flow of a drilling fluid or gas out of the housing, and a packing element assembly within the housing and coupled to the housing. The packing element assembly includes a first packing element affixed to the housing, the first packing element including at least one balloon configured to expand in response to an actuation input, and a second packing element concentrically within the first packing element, the second packing element including a first half and a second half, the first half coupled to the second half by a plurality of elastic elements.
Claims18
A diverter system configured to control a direction of drilling fluid or gas from a well bore to a surface platform, the diverter system comprising:
- a housing configured to receive a casing from a well bore;
- at least one outlet configured to direct flow of a drilling fluid or gas out of the housing;
- and
- a packing element assembly within the housing and coupled to the housing, the packing element assembly comprising:
- a first packing element affixed to the housing, the first packing element comprising at least one balloon configured to expand in response to an actuation input;
- and
- a second packing element concentrically within the first packing element, the second packing element comprising a first half and a second half, the first half coupled to the second half by a plurality of elastic elements;
- wherein the second packing element is configured to receive the casing from the well bore;
- and
- wherein the at least one balloon of the first packing element is configured to compress the second packing element around the casing to seal the second packing element against the casing, preventing flow of the drilling fluid or gas past the packing element assembly and directing the flow of the drilling fluid or gas to the at least one outlet.
A packing element assembly for a diverter system that is configured to control a direction of drilling fluid or gas from a well bore to a surface platform, the packing element assembly comprising:
- a first packing element comprising at least one balloon configured to expand in response to an actuation input;
- and
- a second packing element concentrically within the first packing element, the second packing element comprising a first half and a second half, the first half coupled to the second half by a plurality of elastic elements;
- wherein the second packing element is configured to receive a casing from the well bore;
- and
- wherein the at least one balloon of the first packing element is configured to compress the second packing element around the casing to seal the second packing element against the casing, preventing flow of the drilling fluid or gas past the packing element assembly and directing the flow of the drilling fluid or gas to at least one outlet.
