Abstract
An integrated wellhead assembly is provided to enable free flow production and artificial lift production from a well without requiring removal and/or reconfiguration of the wellhead assembly. The wellhead assembly includes an upper portion and a lower portion forming an integrated assembly. The upper portion includes a flow tee and at least one set of rams. The lower portion includes a shoulder to receive a hanger. The upper portion may seal the bore of the wellhead assembly and provide full bore access to the bore of the wellhead assembly.
Claims26
A system, comprising
- a head, comprising:
- a bore;
- a hanger support;
- a free flow production configuration;
- an artificial lift configuration, wherein the free flow production configuration and the artificial lift configuration are different from one another;
- and
- at least one flow control component configured to selectively move between first and second positions to adjust a flow through the bore while the at least one flow control component is coupled to the head.
A system, comprising
- a head having a bore and at least one flow control component configured to selectively move crosswise to a central axis of the bore, wherein the head is configurable differently to selectively enable free flow production and artificial lift production while the head remains installed at a site, and the head is configurable to enable full bore access while in the free flow production.
A method, comprising:
- changing a configuration of a head between a free flow production configuration and an artificial lift configuration while the head is installed at a site, wherein the head comprises at least one flow control component configured to selectively extend into a bore in the free flow production configuration and the artificial lift configuration.
