Abstract

A wellbore tubular comprising: a base pipe including a wall; a port through the wall providing access between an inner diameter of the base pipe and an outer surface of the base pipe; a nozzle in the port, the nozzle including an orifice including a bend therein.

1 . A wellbore tubular comprising: a base pipe including a wall; a port through the wall providing access between an inner diameter of the base pipe and an cuter surface of the base pipe; a nuzzle in the port, the nozzle including an orifice including a bend therein. 
     
     
         2 . The wellbore tubular of  claim 1  wherein the bend is approximately orthogonal. 
     
     
         3 . The wellbore tubular of  claim 1  wherein the orifice include a main portion and a second portion and the second portion is offset approximately 90° from the main portion. 
     
     
         4 . The wellbore tubular of  claim 1  wherein the orifice is formed as a T including a main aperture portion and a pair of lateral aperture portions extending from the main aperture portion. 
     
     
         5 . The wellbore tubular of  claim 4  wherein the pair of lateral aperture portions are substantially diametrically opposed to each other across the main aperture portion. 
     
     
         6 . The wellbore tubular of  claim 4  wherein the combined cross sectional area of the pair of lateral aperture portions is less than the cross sectional area of the main aperture portion. 
     
     
         7 . The wellbore tubular of  claim 4  wherein the pair of lateral aperture portions each are formed as jetting nozzles. 
     
     
         8 . The wellbore tubular of  claim 1  wherein the main aperture opens into the inner diameter and the pair of lateral aperture portions open on the outer surface. 
     
     
         9 . The wellbore tubular of  claim 1  further comprising a shield installed over the outer surface and a space between the shield and the outer surface and the orifice opens into the space and the bend diverts fluid adjacent the orifice to pass substantially parallel to the outer surface. 
     
     
         10 . The wellbore tubular of  claim 1  further comprising an installation fitting encircling the nozzle, the installation fitting including a passage in which the nozzle is secured and a threaded outer diameter. 
     
     
         11 . A method for handling fluid in a wellbore comprising: passing fluid through a nozzle orifice between an inner diameter of a tubular and an outer surface of the tubular, the nozzle orifice diverting flow such that the flow passes in a non-linear fashion between the inner diameter and the outer surface. 
     
     
         12 . The method of  claim 11  wherein fluid flowing affected by the nozzle at the outer surface flows substantially parallel with the outer surface. 
     
     
         13 . The method of  claim 11  wherein passing fluid includes moving fluid from the outer surface to the inner diameter through the nozzle and creating impinging flows in the nozzle that resists flow through the nozzle. 
     
     
         14 . The method of  claim 11  wherein the wellbore is a producing wellbore in a steam-assisted heavy oil recovery operation and the fluids include steam. 
     
     
         15 . The method of  claim 14  wherein the method further includes resisting the passage of steam through the nozzle orifice to create a steam chamber outwardly of the tubular. 
     
     
         16 . The method of  claim 11  wherein the nozzle includes a body formed of an erosion resistant material; and an orifice through the body, the orifice being non-linear and having a diverting bend to change direction in a fluid flow passing through the orifice. 
     
     
         17 . A nozzle assembly comprising a nozzle having a body formed of an erosion resistant material; and an orifice through the body, the orifice being non-linear and having a diverting bend therealong. 
     
     
         18 . The nozzle assembly of  claim 17  wherein the diverting bend is approximately orthogonal. 
     
     
         19 . The nozzle assembly of  claim 17  wherein the orifice includes a main portion and a second portion and the second portion is offset approximately 90° from the main portion. 
     
     
         20 . The nozzle assembly of  claim 17  wherein the orifice is formed as a T including a main aperture portion and a pair of lateral aperture portions extending from the main aperture portion. 
     
     
         21 . The nozzle assembly of  claim 20  wherein the pair of lateral aperture portions are substantially diametrically opposed to each other across the main aperture portion. 
     
     
         22 . The nozzle assembly of  claim 20  wherein the pair of lateral aperture portions have a combined cross sectional area less than the cross sectional area of the main aperture portion. 
     
     
         23 . The nozzle assembly of  claim 20  wherein the pair of lateral aperture portions each is formed as jetting nozzles. 
     
     
         24 . The nozzle assembly of  claim 17  wherein the nozzle is substantially cylindrical with ends and cylindrical side walls extending between the ends and the main aperture portion opens at an end and the pair of lateral aperture portions opens on the cylindrical side walls. 
     
     
         25 . The nozzle assembly of  claim 17  further comprising an installation fitting encircling the nozzle, the installation fitting including a passage in which the nozzle is secured and a threaded outer diameter.
