SpecialReport: Completion Technology A second test evaluated the perforating system's ability to be successfully deployed with all the constituent materials of the propellants and tracers. Full gun systems were loaded with perforating charges, propellant and tracer. The perforating guns were placed inside sample pieces of wellbore casing and detonated in a fashion that replicated downhole conditions. After the test was complete, the perforating guns were recovered and analyzed. Swell measurements were taken to verify that the nominal outer diameter of the carrier was acceptable to manufacturer standards. Next, the exit holes in the gun carrier were measured to make sure there were no visible issues with the perforating charges. No issues were found with the system during this test. The final test of the perforating gun was evaluating the delivery mechanism of the tracer material. There were several designs for the tracer material packaging FIGURE 2 PGT Returns Over Time Perf Gun Tracing - Toe Flow Assurance 0.4 Well 1H - Stage A 0.3 Well 1H - Stage B Well 2H - Stage A Well 2H - Stage B 0.2 FDI From Offset Frac 0.1 0.0 010 20 30 40 50 Time From Initial Flowback [DAYS] 60 70 80 Print It's Classy.
