摘要： A system monitors and controls the injection of additives into formation fluids recovered through a well may include a plurality of nozzles that receive the injection fluid from an umbilical disposed in a well. Each nozzle may have an associated flow control element that is configured to affect a flow of the injection fluid ejected through the associated nozzle. The umbilical may include one or more filters positioned in a first of two parallel conduits formed along the umbilical. An occlusion member restricts in a second of the two conduits. The occlusion member permits flow in the second conduit after a predetermined pressure differential exists in the second conduit. The system may include a plurality of pressure sensors disposed along the umbilical, and an injector unit that dispenses fluid into the umbilical. A controller operatively coupled to the injector unit operates the injector in response to measurements from the pressure sensors.

摘要： 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.

摘要： Apparatus for recompleting an oil and/or gas well includes a primary tubing hanger, and primary well tubing hung from the hanger within the well, and a communication/hanger nipple, located below the primary tubing hanger, which is suitable for receiving and locating a coiled tubing hanger. The communication/hanger nipple is run into the well as part of the initial completion in any situation where there is a potential requirement for a coiled tubing completion later in the life of the well but plays no part in the normal primary production operation of the well. However, should production fail for any reason, requiring coiled tubing recompletion, the communication/hanger nipple is available to support the coiled tubing and provide communication to the subsurface equipment without the necessity of modifying the primary tubing hanger.
