Current Situation
• Currently,
• Sec. 10 Static fluid-loss testsThe screens shall be replaced when they show visible plugging, wear,damage, or distortion. (API RECOMMENDED PRACTICE 10B-2SECOND EDITION, APRIL 2013)
• Problems noticed when testing FLAs for acceptance criteria & comparing FL data with SC.
• API spec for Blade Wear:
• Discard if mass loss >10 %

3 Choices
1. Change complete screen every time
• Costly
2. Change the 325 mesh screen every time (split rings)
• 60 mesh screen half thickness ring 325 mesh on top and blank ring on top. Need perforated disk type for strong backing
3. Use Plastic FL screen tester to determine flow rate
• Continue with screens currently provided

Lab – Lab Results
• Variables running the test are:
• Technician – accuracy of performing FL test
• Pressure delivered
• Screen
• Visibility
• Weight
• Flow rate
![Page 44: WG on Determination of Fluid Loss Screen Life API SC 10 Scott Jennings 25 June, 2013 2013 Exploration and Production Standards Conference on Oilfield Equipment](https://reader031.vdocument.in/reader031/viewer/2022013011/56649cad5503460f9496fee9/html5/thumbnails/44.jpg)

Initial Findings• Labs discard screens at technician discretion (Vis.).
• Unattended test lead to higher degree of uncertainty.
• Tech. around but not totally on top of test.
• N2 source should have a defined min. starting supply pressure for the static test.
• regulated pressure down to 1000 psi diff.
• 1200 psi on stirred FL apparatus

Flow Rate Determination Procedure (New Screen)
1. Weigh FL screen dry
2. Soak in water for 2 mins.
3. Assemble FL cell
4. Fill cell with 165 gr. Water SG=1.00
5. Open drain valve and start clock simultaneously
6. Stop clock and record time when water level has left the inside of the cell.
7. Dry with compressed air
8. Repeat steps 4-7 four more times

Initial Study• 26 new screens weighed (metal backed)
Ave. 21.99 gr.
High 22.24 gr.
Low 21.52 gr
• 5 screens selected for water flow test
• Water gravity flow test
165 grams of water flow through cell (SG-1.00)
5 test times recorded (sec)
Rates calculated (ml/sec)
Best match to average was selected (screen no. 5)

20 FL Tests Performed•10 slurries selected 115-283 cc’s/30 mins.
Screen weighed before FL test
Water Flow Rate determined before FL test
2 tests made 30 mins.
•Same 10 slurries repeated 120-215 cc’s/30 mins.
Screen weight increased from 22.01 to 22.08 gr.
4 tests made 30 mins.
•Can continue if SC 10 is interested.
New FL Screen no. 5 Selected
