WearSox® TESTING |
| |
| 2009 Corrosion Test |
| |
Several standardized corrosion tests were conducted on WearSox Silver in order to better characterize its corrosion resistance. |

| 2008 Stress Engineering Aluminum Drill Pipe |
| |
Stress Engineering Services, Inc. performed resonant fatigue tests on aluminum pipe to test the retention of the WearSox on the pipe. The WearSox were not damaged by the test after a total of 4.5 million cycles. |

| 2008 Stress Engineering Resonant Bending (15deg/100ft + 15kpsi internal pressure) |
| |
In light of more demanding operating conditions, the original bonding test of 2005 was repeated with the addition of 15,000 psi internal pressure and bending radii up to 15 deg/100ft. The duration of the test was also extended to 3.5 million cycles. The band as applied using our stringent quality controlled applications procedure, survived the test without any cracks or spalling. The fracture of one of the bands was deliberate and confirmation of the necessary preparation practices. |

| 2008 Accu-Test, Drop Weight (crush /bonding) |
| |
This test was conducted to determine WearSox® resistance to shock loads and an 18 inch drop test has since been adopted as a standard qualification test for all new applicators. The low temperature test was an extension of the first for Arctic use considerations. |

| 2007 Grant Prideco DEA-42 Friction and Wear |
| |
ConocoPhillips and WearSox® approached Grant Prideco to perform base-line wear testing of the WearSox® material on the Grant Prideco Casing Wear Machine. If the material proved to be suitable, ConocoPhillips intended to use WearSox® to fabricate metallic centralizers directly on to casing and to the OD of the DwC connections. As a result of this test, ConocoPhillips has used WearSox® extensively for casing drilling. |

| 2005 Stress Eng. Resonant Bending (5deg/100ft) |
| |
This test was the first to establish the bond integrity of WearSox® wearbands when subjected to the cyclical bending stresses exceeding those anticipated in service. |

| 2005 Mohr Engineering Friction and Wear in ExxonMobil Oil Based Mud |
| |
ExxonMobil paid for modified DEA-42 tests to be conducted on our product. WearSox® engaged Mohr Engineering to run the test again, only for a longer time. The report is attached below. At that time we were still testing a short list of two materials , WearSox® 30 and 64. As a result of this test we selected 64 exclusively and named it "Silver" |

| 2005 Tensile Test |
| |
This test was performed to assess the integrity of WearSox® when subjected to 80% of drill pipe yield strength, simulating the elastic deformation encountered during critical operations, such as stuck pipe. |
