Tejas Research & Engineering, LLC 9185 Six Pines Drive The Woodlands, Texas 7738 PRESSURE TESTING REPORT Nexgen - 5352 - Plug Testing (Plug #2) Casing Drift: 4.375" 29-Sep-16 Plug OD: 4.25" Tools: T4 Hydraulic Setting Tool (Baker 2) Nexgen Oil Tools X-Factor Frac Plug (Gen 3 rubber seal) 5.5" 26.8# Q-125 Casing Max Pressure 13,3 psi (Max test pressure 1,5 psi) 8:3 - Hold pre-test JSA with customer and begin set up for frac plug testing. 9:45 - Make up plug with supplied WL adaptor kit. Set plug at ambient temperture of 72 F. Measure from top of plug to top of casing. Plug slip ring breaks at 4, psi. Plug shear and set at 42, psi. 1: - Lower test casing and set plug into well to begin test. Having trouble keeping pressure. Trouble shoot for problem. Change out pressure fitting on Tejas' pressure line. 11:8 - Begin pressure test at ambient temperture of 75 F. Bring pressure above casing to 2,5 psi, bring bottom pressure to 5 psi. Continue to regulate pressure above and below plug to achieve an 8,5 psi differential. Achieved 1,2 psi above and 2,3 psi below. Hold pressures losing <4 psi/hour. 13:45 - Start heater. Regulate pressure during heating phase so as not to exceed 1,5 psi max. Reach 2 F at 15:3 hrs holding 1,3 psi above and 1,5 psi below. Begin phase two of test. 16:25 - Per customer request, bleed bottom pressure down to zero psi. Customer wants to hold a 1, psi differential on plug. 16:5 - Customer calls good test after holding 1, psi differential on plug for 3 minutes. 17: - End Test. Begin cooling down and bleeding down pressure from chamber. 18: - Remove casing to inspect plug. Measure from top of plug to top of casing. Plug did not move during pressure test. Customer confirms good test per procedure. Remove plug from casing with Tejas 1 ton hydraulic press.

Set plug at ambient temperture of 71 F. Measure from top of plug to top of casing. Plug slip ring breaks at 4, psi. Plug shear and set at 4, psi. 9:45 - Lower test casing and set plug into well to begin test. Begin heating chamber and regulating pressure not to exceed 1,5 psi max pressure. 11:15 - Reached temp of 2 F at 6,25 psi. Experienced extreme pressure drop. Found leak on fitting going to chamber. Pressured back up with communication under plug. Could not regain steady holding pressure. Stop test to inspect casing/plug. Begin cool down and bleed down pressure. 12:3 - Remove casing from test chamber for to inspect plug. Measure from top of plug to top of casing. Plug did not move. Customer confirms measurment my Tejas technician. Inspect casing and found diformity on exterior of casing. Remove plug with Tejas 1 ton hydraulic press. Mic inside of casing. Drift of casing shows inconsistant. Measures 4.376" to 4.55". By Tejas saftey standards, test casing is no longer safe to use and must be discarded or destroyed. Customer confirms findings and ends testing at 14:5 hrs.
