4 Volume XXIV - No. 4 Oct. Dec. 2007 Effects of H 2 S on OCTG The International Pipe Inspectors Association API RP 7G discusses the effects of H 2 S on the drill stem in Section 8. The discussion is covered under the broad title of Sulfide Stress Cracking, and the explanation states that embitterment is caused by the absorption and diffusion of atomic hydrogen. This mixing of the terms Sulfide Stress Cracking and hydrogen embitterment is common in the literature. National Association of Corrosion Engineers (NACE) in their publication Corrosion Control in Petroleum Production state, A major reason for the proliferation of names is a lack of agreement as to the mechanism of failure. Some investigators argue that sulfide stress cracking is a form of stress corrosion cracking, while others offer evidence that it is a form of hydrogen embitterment." If the experts disagree on the cause embitterment failures it is certainly beyond our expertise to explain it. The conditions that lead to embitterment failures are agreed on and are listed below: 1) High strength or hardness steel 2) Stress on the steel 3) Presents of atomic hydrogen and H 2 S 4) Time 5) Temperature The details of each of these conditions are explained in Section 8, of API RP 7G. This of course still creates problems when buying used pipe, there is no test to detect actual hydrogen in the pipe. "Until steel containing hydrogen actually cracks, there is no permanent damage. In many cases, the hydrogen can be baked out by suitable heat treatments, and the original properties of the steel can be restored." 1 Inspection techniques can detect cracks but there is no technique for the detection of hydrogen entrapped in the steel. The API pamphlet Corrosion of Oil-and Gas- Well Equipment describes a procedure for detecting iron sulfide on steel equipment. This procedure describes the material needed and the procedure for detecting the presence of iron sulfide in steel pipe. This test may be performed on steel downhole equipment suspected of having hydrogen sulfide present. The test may be performed on the tool joint or the pipe body. Because the chemical reaction between H 2 S and steel produces both irons sulfate and free hydrogen, this test for iron sulfate is considered to test for exposure to H 2 S. The iron sulfate will remain on the surface of the metal even after the hydrogen has dissipated out of the material. The material used is acidic so none of the material used should come into contact with the skin. If contact is made, immediately flush with plenty of water. Contact a doctor if burning persists. MATERIAL: 1. Glass container capable of holding approximately 100 ml of solution 2. One eye dropper or syringe 3. Chemicals MIX THE FOLLOWING IN CLEAN GLASS CONTAINER a. 15-percent hydrochloric acid containing b. 1.0 percent sodium arsenite (NaAsO 2 ) c. 0.05 percent of liquid detergent (not soap) d. 83.5 percent distilled water PROCEDURE: Find a spot of bare metal on either a tool joint or the pipe body. The test spot should be approximately one inch square. Use the eye dropper, or syringe to put a single drop of the solution in the center of the area. Wait approximately one minute. If hydrogen sulfide is present, the liquid will turn bright yellow. A dark yellow/green indicates a high level of H 2 S is present. A light color indicates a low level. Since some iron may be dissolved by the acid, a yellow-orange solution may result. This should not be mistaken for the yellow precipitate formed by the sulfide. Caution- This test should only be used on steel equipment. Do not use on aluminum or metal plating, because poisonous fumes may be
