Set plug at ambient temperture of 72°F. Measure from top of plug to top of casing. Plug slip ring breaks at 4,000 psi. Plug shear and set at 42,000 psi. 10:00 - 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. 11:08 - Begin pressure test at ambient temperture of 75°F. Bring pressure above casing to 2,500 psi, bring bottom pressure to 500 psi. Continue to regulate pressure above and below plug to achieve an 8,500 psi differential. Achieved 10,200 psi above and 2,300 psi below. Hold pressures losing <40 psi/hour. 13:45 - Start heater. Regulate pressure during heating phase so as not to exceed 10,500 psi max. Reach 200°F at 15:30 hrs holding 10,300 psi above and 1,500 psi below. Begin phase two of test. 16:25 - Per customer request, bleed bottom pressure down to zero psi. Customer wants to hold a 10,000 psi differential on plug. 16:50 - Customer calls good test after holding 10,000 psi differential on plug for 30 minutes. 17:00 - End Test. Begin cooling down and bleeding down pressure from chamber. 18:00 - 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 100 ton hydraulic press. PRESSURE TESTING REPORT

08:30 - Hold pre-test JSA with customer and begin set up for frac plug testing.
09:45 - 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 4,000 psi. Plug shear and
set at 42,000 psi.
10:00 - 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.
11:08 - Begin pressure test at ambient temperture of 75°F. Bring pressure above casing to 2,500
psi, bring bottom pressure to 500 psi. Continue to regulate pressure above and below
plug to achieve an 8,500 psi differential. Achieved 10,200 psi above and 2,300 psi below.
Hold pressures losing <40 psi/hour.

Nexgen - 5352 - Plug Testing (Plug #3) Casing Drift: 4.375"
30-Sep-16 Plug OD: 4.25"
Tools: T4 Hydraulic Setting Tool (Baker 20) Nexgen Oil Tools X-Factor Frac Plug (Gen 3 rubber seal)
5.5" 26.8# Q-125 Casing Max Pressure 13,300 psi (Max test pressure 10,500 psi)
08:00 - Hold pre-test JSA with customer and begin set up for frac plug testing.
09:05 - Make up plug with supplied WL adaptor kit. Set plug at ambient temperture of 71°F.
Measure from top of plug to top of casing. Plug slip ring breaks at 4,000 psi. Plug shear and
set at 40,000 psi.
09:45 - Lower test casing and set plug into well to begin test. Begin heating chamber and regulating
pressure not to exceed 10,500 psi max pressure.
11:15 - Reached temp of 200°F at 6,250 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.
12:30 - 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 100 ton
hydraulic press. Mic inside of casing. Drift of casing shows inconsistant. Measures 4.376" to
4.505". 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 14:50 hrs.
