70 the sacrificial impingement straps 71 keep the steam from directly impinging on the slotted liner 67 and thus prevent the possible erosion of the liner 67 based on experiment and experience it is known that about a rate of 5 barrels of steam per day per foot of horizontal section is desirable also about 500 barrels of steam per acre foot is desirable with these as goals and knowing the tubing diameter and steam delivery pressure calculations allow the spacing and size of drilled holes 70 to be made for a particular well the drilled holes 70 and sacrificial impingement straps 71 are usually symmetrically arranged along the tubing 65 and about its circumference in practice a typical field procedure to run steam to a well using this 34 steam stinger 34 as described would be as follows 2 run in on a tubing string the steam stinger designed for this well 3 deliver the steam from the generator to the steam stinger via the tubing string 4 inject steam until the desired volume of steam is injected via the stinger 6 reinstall the artificial lift equipment into the well and place the well back onto production this technique can be cyclically repeated when the produced volume of hydrocarbon fluid falls below an acceptable volume in the.
