Abrégé

The present invention concerns gasket apparatus comprising a substantially annular metallic element (1; 10) having an outwardly projecting rib (2; 12). The annular element has an inner concave profile and wherein outer surfaces (13, 14) of the annular element either side of the rib are angled or arcuate relative to the central axis of the annular element, to present sealing surfaces for engaging with tubular, wellhead or connector seat member surfaces. More particularly, where the outer surfaces of the annular element are angular, they are inclined at 22° to 23° to the annular element axis. Moreover, the surface finish on the inclined or arcuate outer sealing surfaces are Ra Micro Meter: 0.6/(Ra Micro Inch: 24) or finer. Further, the outer inclined or arcuate outer sealing surfaces have a metal based coating.

An apparatus and method for collecting fluid from a drill string or borehole casing includes a collection casing having means for sealably engaging around a drill string or borehole casing to create a chamber between the interior of the collection casing and the drill string or borehole casing, and one or more fluid nozzles for directing cleaning fluid into the interior of the chamber. The one or more nozzles are configured to direct cleaning fluid to impact the inwardly facing interior surface of the collection casing.
