Feasibility Study Phase I Completed 9/18/10

EMOPP Phase I feasibility study has been successfully completed as of September 18, 2010.  Phase I tested key working assumption #5 and passed with flying colors.

Working Assumption #5 Test Details:

Test electromagnetic JAWS to determine if they are strong enough to prevent slip on a carbon steel surface when subjected to forces up to 1,000,000 - 2,000,000 lb-force range. For example the feasibility study simulated a test where an equivalent well shut-in pressure of 10,000 psi was applied to the JAW device without slippage.  The force was applied in the direction of flow on the face of a carbon steel plate to simulate a shearing effect. Slippage did not occur at simulated pressures up to 10,000 psi in a 12 inch pipe (i.e. up to 1,085,374 lb-force).  In other words the  JAW device did not move, but stayed put.  The test was limited to 10,000 psi due to max instrumentation range.  In other words the test equipment could not see above a 10,000 psi equivalent pressure. Thus the feasibility study was only able to observe up to 10,000 psi equivalent pressure due to instrumentation max range limitations.  The feasibility study phase I test was an overwhelming success and places EMOPP one step closer to commercialization.

The key to successful phase I test was the use of an epoxy between the magnet and steel wall/face. Without the chemical bonds the magnetic "JAW" did slip. Thus, the key to using an EMOPP device is to use the magnetic b-field to temporarily secure the JAW to the pipe wall without restricting flow and generating a Delta P. Once the epoxy cures, then flow restriction may commence.
