Some important points to follow when using this tool:

1. Determine a static fluid level

2. Verify integrity of Sand Line

3. Orient rig to flow-back tank in order to monitor returns

4. Limit Lineal Pull to no more than 30 meters

5. Swab above perforations

6. If working below perforations, run tool quickly past that zone

7. Move tool as quickly and as steadily as possible

8. As the tool operates:

   1. Look for solids such as coal, shale, etc. to diminish

   2. Look for sand production to stabilize

   3. Water cuts may start at 5% and go to 50% before stabilizing at 20%

9. Divide the swabbing volume by 4 to determine the minimum pump capacity
