Document Type and Number:
WIPO Patent Application WO/2015/065756
Kind Code:
A3
Abstract:
A wellhead assembly (11) includes a tubular wellhead housing (13) having a bore (15) and an annular gallery slot (23). The annular gallery slot is defined by an enlarged inner diameter of the bore. A tubular hanger (17) is selectively landed in the bore of the wellhead housing, defining an annular cavity (21) between the bore and an outer diameter of the tubular hanger. The tubular hanger is supported by the wellhead housing with a hanger support (19) located in the annular cavity. A flow-by passage (37) is in fluid communication with the annular cavity at locations above and below the hanger support. The flow-by passage intersects with the gallery slot and intersects an outer radial surface of the tubular hanger.
