Abstract: A tool and method to remove sand and other types of solid particulate materials and fluids from wellbores and conduits, resulting from well-drilling, well-production or both, and consequently to reactivate well production. The modular tool, composed of different subsystems, is connected to the end of concentric coil tubing, operates promoting the aggregates disintegration by using a spiral jet to impact these solids and suctioning the small particles and well fluids, simultaneously or later, by using jet pumps based on a set of several venturis. Changes between different operation modes are imposed by modifying surface pump pressure levels and the tool does not need to be removed from the wellbore between different stages, reducing the overall operation time.

Abstract: A coiled tubing venturi junk basket tool retrieves junk, debris and/or wireline from a wellbore. A collection housing or waste basket is removeably coupled to the venturi body. The collection housing (waste basket) is customizable for volume, hole diameter and the type of junk and debris retrieved. An elastomeric trap is used to retain junk and debris in the collection housing. The collection housing is also interchangeable with a grab housing for retrieving wireline.

Abstract: The gas lift accelerator is a method and a downhole apparatus based on the principle of the jet pump to allow the extraction of reservoir fluids up to high API grade with low or no reservoir pressure, at any depth, by injecting available gas in the oil field, allowing the flexibility of operation on diverse well completion configurations like sliding sleeve type and gas lift mandrels, complementing the operating when other methods like traditional gas lift procedures or hydraulic fluid jet pumps are not effective. The gas lift method includes the use of downhole and surface metering data to optimize the operation of the gas lift accelerator apparatus.

Abstract: A wash nozzle assembly for comprising a cylindrical nozzle body component having a proximal end with a demountable coupling device for engaging a supply of high-speed fluid, and a distal end; a cylindrical nozzle tip component having a proximal end for demountable coupling with the distal end of the cylindrical nozzle body, and a conical distal end, said conical distal end having at least one orifice; at least one O-ring mounted onto the distal end of the cylindrical nozzle body; a swirl plate mounted into a juncture of the cylindrical nozzle body and the cylindrical nozzle tip component, the swirl plate having at least one channel therethrough; and a three-dimensional flow interrupter component housed within the cylindrical nozzle tip component. The wash nozzle assembly can be demountable engaged with an end of coiled tubing for cleaning and washing debris from a wellbore.

Abstract: A tool and method based on proven technologies, to remove sand and other types of solid particulate materials and fluids from wellbores and conduits, resulting from well-drilling, well-production or both, and consequently to reactivate well production. As time passes, solid aggregates are consolidated, plugging the wellbore, so they can be removed following two stages: disintegration in small particles and its further transport to surface. The tool, modular, composed of different subsystems, is connected to the end of concentric coil tubing, operates promoting the aggregates disintegration by using a spiral jet to impact these solids and suctioning the small particles and well fluids, simultaneously or later, by using jet pumps based on a set of several venturis. Changes between different operation modes are imposed by modifying surface pump pressure levels and the tool does not need to be removed from the wellbore between different stages, reducing the overall operation time.

Abstract: The present application discloses a system and method of guiding one or more strings of coiled tubing into a wellbore as the strings of coiled tubing are pulled into the wellbore by another coiled tubing string. The present application also discloses coiled tubing equipment for the insertion of the additional coiled tubing strings into the wellbore.
