AbstractNOVELTY - The apparatus has an inner thermal insulation and an outer waterproofing shell made of fabric material. Velcro (RTM: Hook and loop fastener) strips are arranged along edges of the apparatus so as to allow the apparatus to be easily secured to a gas/oil wellhead, where the apparatus is attached to the wellhead to prevent freezing of fluid or gas contained in a wellhead lubricator (1) and used in association with fluid transfer hoses contained in fluid transfer lorries to prevent freezing of the fluid or gas contained in the hoses. ADVANTAGE - The apparatus is light in weight, can be manufactured at low cost, and is user-friendly, easily transportable and quickly attached to the wellhead while sufficiently withstanding cold weather environments. The apparatus is used in association with the fluid transfer hoses contained in the fluid transfer lorries to prevent freezing of the fluid or gas contained in the hoses so as to prevent freezing without the need of heat and/or external power source. The apparatus can be adapted to fit with different sizes and types of wellheads. DESCRIPTION Of DRAWING(S) - The drawing shows a side view of a wellhead with a wellhead protector.Wellhead lubricator (1)Piping (2)Wellhead tubing (3)Wellhead isolation valves (4)Casing/tubing strings (5)
