’Stroker Series™’ Heavy Sand Testing Nisku, Alberta, Canada
Test was indoors with the aforementioned hydraulic unit and 7” casing test unit. Flow rite flow meter and Omega pressure transducer. This was the first test of the new tapered seal and housing design. The flow meter was reset between every test. 36” stroke length.
TEST #1 Water. Basic water valve fully open.
This was a water test @ 20C indoors @ Mazz Jan 17 2020. Using 36” stroke with a 20lb spring in stalled the height of the lower piston was level to the bottom edge of the inlet port.
Hydraulic unit was a 13.5hp Honda motor with a 19GPM HPU, 15 Gal res tank with filter and a high flow equalizing/combining valve with 2” hydraulic rams.
The water was filled into the anulus of the casing from the top and draw in from the tool inlet ports. It was then circulated up the tubing through the fill rite flow meter and Omega transducer back through the hose to the bottom of the casing thus refilling the anulus. A total of 10.18 Gal was pumped. The Cum. Screen shot shows the restricted movement of the rams as Shawn was getting used to the hydraulics.
Result
Results 6.33Gal on 16 strokes. 0.395625gal/stk. This test was performed with the make up water turned off. The tools was ran dry and the water turned back on to complete the test. This was done to see how far down we could draw water down before the ports, a reference mark was then place on the casing.
TEST #2 Water with the lower ball valve closed 50%.

The water was filled into the anulus of the casing from the top and draw in from the tool inlet ports. It was then circulated up the tubing through the fill rite flow meter and Omega transducer back through the hose to the bottom of the casing thus refilling the anulus. The lower ball valve was closed 50% to restrict the flow. A total of 18.16(-10.18 from previous is 7.98). The difference in total gallons pumped is attributed to the added restriction of closing the ball valve.
Result
Result was 5.39 on 8 strokes. 0.67375gal/stkThis was the most accurate test of the 5 gal pail. The make up water was turned on at the start to ensure we had maximum flow. .22gal/ft stk, 0.0052gal/ft/stk or 100% efficient
TEST #3 Water test, lower valve to casing closed 100%
This was a water test @ 20C indoors @ Mazz Jan 17 2020. Using 36” stroke with a 20lb spring in stalled the height of the lower piston was level to the bottom edge of the inlet port.
Hydraulic unit was a 13.5hp Honda motor with a 19GPM HPU, 15 Gal res tank with filter and a high flow equalizing/combining valve with 2” hydraulic rams.
The water was filled into the anulus of the casing from the top and draw in from the tool inlet ports. It was then circulated up the tubing through the fill rite flow meter and Omega transducer back through the hose to the bottom of the casing thus refilling the anulus. The lower ball valve was closed 100% to restrict the flow. Gallons pumped was not observed as this was only to test the pressure of the tool and its high level.
The test was stopped as the stuffing box began leaking at 40PSI. The high level of 40PSI was not recorded as Kyle accidentally logged out of the Omega program and lost the data. A second test was ran and the results are labeled as test # 3.
Result
Test # 3 was done with H2O and the hose connected back to the 7” casing thus closing the loop in the system. The valve was in the 100% open position allowing circulation. The annulus vol was topped up close to the top to balanced position. We are going to do 20 strokes and record the total flow and observe pressures. This has been our base line test.
TEST #4 Water test, lower hose disconnected.
Casing will be pumped dry and refilled on the fly several times. This test will simulate real time cavitation results.

The water was filled into the anulus of the casing from the top and draw in from the tool inlet ports. It was then circulated up the tubing through the fill rite flow meter and Omega transducer back through the hose to the shop drain. A total of 27.25 (9.09)Gal was pumped.
The tool was pumped dry for roughly 30sec, then the casing was top filled. The tool started pumping as soon the fluid level was above the inlet ports as water was observed flowing again out of the hose into the shop drain. This process was repeated to simulate a run dry scenario and introduce air(gas) into the fluid column. The reason for this was to prove that the tool will not cavitate and starve for fluid once gas is introduced into the system.
Result
Test # 4 was done with H2O with a fluid viscosity of 100+and the hose connected back to the 7” casing thus closing the loop in the system. The valve was in the 100% open position allowing circulation. The annulus vol was topped up close to the top to balanced position. We are going to do 20 strokes and record the total flow and observe pressures. This has been our base line test. Calibration is at 19.
Results 0.33Gal on 20 strokes. 0.Gal/stk .151gal/ft/stk, 0.00bbl/ft/stk. % efficient. The flow meter become clogged by the polymer fluid. The turbine is not accurate.
TEST #5 Water with 4.75” dump sub spring set all the way down.
Basic water valve fully open. This was a reference test to test 31.
This was a water test @ 20C indoors @ Mazz Jan 17 2020. Using 36” stroke with an unknown #lb spring installed the height of the lower piston was ¾” below the bottom edge of the inlet port.
Hydraulic unit was a 13.5hp Honda motor with a 19GPM HPU, 15 Gal res tank with filter and a high flow equalizing/combining valve with 2” hydraulic rams.
The water was filled into the anulus of the casing from the top and draw in from the tool inlet ports. It was then circulated up the tubing through the fill rite flow meter and Omega transducer back through the hose to the bottom of the casing thus refilling the anulus. A total of 11.50 Gal(possible error) was pumped.
We had reset the fill rite flow meter and were not sure what the actual reading was. We went to reset the meter after the test to confirm and noted that the number was 41.88 (11.50) gal this was an increase of 2.41 gal over the 20lb spring.
