Today the Oil and Gas Industry is experiencing severe internal corrosion of high-pressure gas-condensate Well tubing and well-head fittings. This presents the industry with a serious economic as well as with a safety problem. The expense of shutting in a well and replacing the corroded tubing, along with the loss in production during the time the well is shut in, increases the cost of production and decreases the revenue realized from the field as a whole.
The economic importance of internal corrosion of tubing in high-pressure gas-condensate wells was very well brought out in a paper presented before the Annual Convention of the N.A.C.E. in April, 1944, by T. W. Johnson (1). He states that, “due to the uncertainty of where internal corrosion has occurred, precautions have to be taken which increase the cost of killing the well and replacing the corroded equipment.”
In a paper before this same convention,...
