This shows heavy spalling of the case hardened sucker rod caused by hydrogen embrittlement.
Coated pony bar at left tested in high H2S crude shows no corrosion damage after one year
Uncoated pony bar at right tested in the same well shows heavy corrosion damage after one year.
This pony rod was cut in half to show the coating condition after testing in the well for six months. The top section was clean to show that the coating was still intact and the section at the bottom shows the rod as it came out of the well.
Aliron Tool Research developed this coating for the purpose of offering well operators a solution to corrosive downhole problems with a performance level at or above the prevailing plastic coatings and fiberglass liners. With this coating well operators can achieve the same or better corrosion resistance at a significant cost reduction.
The laboratory and field test program, as well as the three year results of the coated steel pin-ends of a fiberglass sucker rod string in the Waddell et. al. Amaine 69, have yielded great success. Now Aliron Tool would like to leverage this success by coating the inside surface of oil country tubular products and other viable components on a larger scale. At this point the test results indicate this coating will successfully provide excellent corrosion protection in very aggressive fluids, resist very tough handling and high temperatures at a significant cost savings. With this goal in mind, Aliron Tool Research is seeking the input and assistance of the Artificial Lift community to develop 100 blast joint prototypes for field use and eventual commercialization.
