LAB + BENCH TESTING

Testing

PolyLoc dissolution, bridging and comparison-test results with measured endpoints, supporting photos and direct time-lapse video.

PolyLoc Temperature-Series Dissolution

Verified time to 0.0 g measurable dry residue

Each bar shows the documented test endpoint when no measurable dry material was retained on the screen. Intermediate mass values were not measured; each bar represents a separate bench test.

3D SLOT TEST

86% fluid retained through a 0.025-inch slot

20 cp guar • 5-minute conditioning • 200 psi • 0.025-inch slot • 15-second test

PolyLoc was conditioned in a 20 cp guar solution and tested through a narrow slot under pressure. The recorded test retained 86% of the fluid, supporting temporary bridging / pack-off behavior.

LEADING COMPETITIVE PRODUCT 140°F

140°F Comparison Test

A 2.0 g starting sample was tested for 48 hours at 140°F. Initial dry strainer: 56.2 g; final dry strainer: 58.2 g. This indicates 2.0 g (100%) measurable screen-retained material after the test.

Time-lapse frequency: approximately 1 frame every 3 minutes.

EXTENDED 200°F COMPARISON TEST

Leading Competitive Product — 6-Day 200°F Test

2.0 g start • 6-day endpoint • 0.4 g measurable retained material • 20% retained • 80% pass-through

The initial dry strainer weighed 56.3 g. After six days at 200°F, followed by straining and drying, the final dry strainer weighed 56.7 g. The 0.4 g increase represents 20% of the original 2.0 g sample remaining screen-retained at the six-day endpoint.

Mass-equivalent perspective

A 20% retained fraction is equivalent to 200 lb of material per 1,000 lb deployed. If a comparable retained fraction occurred downhole, that residual material would represent material not cleared from the treated interval. This bench test does not directly measure downhole retained mass or production impairment; it demonstrates incomplete cleanup under the recorded test conditions.

The photographs document the fluid condition during refrigeration and approximately 24 hours afterward. Visible particulate / solid material remained observable during this follow-up observation.
