Abstract
A fluid communication nipple including a tubular mandrel having an interior surface defining an internal bore and a passageway extending substantially lengthwise along a portion of the mandrel. The passageway is defined by an exterior wall section and an interior wall section, wherein the interior wall section extends outward from the interior surface into the bore. When it is desired to establish fluid communication through the passageway between the exterior and interior of the nipple an opening is formed through the internal wall section.
Claims20
A fluid communication nipple for establishing radial fluid communication between the outside of the nipple and the inside of the nipple, the nipple comprising:
- a tubular mandrel having an interior surface defining an internal bore;
- and
- a passageway extending substantially lengthwise along a portion of the mandrel, the passageway defined by an exterior wall section and an interior wall section, the interior wall section extending outward from the interior surface into the bore:
- wherein fluid communication is established through the passageway by puncturing the interior wall section.
A fluid communication nipple for establishing radial fluid communication between the outside of the nipple and the inside of the nipple without the use of moving parts or elastomer or metal-to-metal seals, the nipple comprising:
- a tubular mandrel having an interior surface defining an internal bore;
- and
- a passageway extending substantially lengthwise along a portion of the mandrel, the passageway defined by an exterior wall section and an interior wall section, the interior wall section extending outward from the interior surface into the bore:
- wherein fluid communication is established through the passageway by puncturing the interior wall section.
A method of establishing radial fluid communication between the exterior of a well tool and an interior of a well tool, the method comprising the steps of:
- providing a tubular mandrel having an interior surface defining an internal bore;
- providing a passageway extending substantially lengthwise along a portion of the mandrel, the passageway defined by an exterior wall section and an interior wall section, the interior wall section extending outward from the interior surface into the bore, wherein fluid communication through the passageway is closed;
- connecting the mandrel within a tubular string;
- disposing the tubular string carrying the mandrel in a wellbore;
- and
- creating an opening through the interior wall section providing fluid communication between the exterior of the mandrel and the interior of the mandrel through the passageway.
