PROGRESS REPORTS
WEEK 1 (Jan. 31 - Feb. 4, 2000)
-
Data Acquisition was obtained for three different speeds; 6 strokes
per minute (spm), 9spm, and 12spm.
-
The following graphs
(Excel format) were done for the three different speeds:
-
Position vs Time
-
Intake Pressure vs Time
-
Discharge Pressure vs Time
-
Barrel Pressure vs Time
-
Annular Pressure vs Time
-
Load vs Time
Data
file in text format.
WEEK 2 (Feb. 21 - Feb. 25, 2000)
-
Data acquisition at speeds from 6 to 16spm for both full pump and pumping
off.
-
Data acquisition at different speeds for both full pump and pumping
off. Videos were taken during the test.
WEEK 3 (Feb. 28 - Mar. 3, 2000)
-
An additional load cell was installed. A test was done in order
to check the "zero readings" for both the load cells and pressure gauges.
Data for the second load cell was acquired with the "Echometer TWM" system.
-
Valve checks were recorded as well as sets for one minute pumping with
full pump.
-
Web page was updated with new video clips.
WEEK 4 (Mar. 20 - Mar. 24, 2000)
-
The position of Beam Pump Unit was corrected to improve the alignment
with respect to polished rod.
WEEK 5 (Mar. 27 - Mar. 31, 2000)
-
Stuffing Box assembly was replaced with "O" ring seals to reduce friction.
-
A test was done to check the behavior of measured parameters after the
modifications done on stuffing box and Beam Unit.
WEEK 6 (Apr. 1 - Apr. 9, 2000)
-
Tests were run at two speeds and variable pump fillage.
-
Leak was discovered at fitting on Standing Valve. Workover is
now needed.
