WELL #3 As we reviewed the video on Well #3 with you the other day, we determined that a patch was necessary at the missing Western plug area at 493 feet. In addition, the well must be swabbed and gravel pack re-established. It would be advisable to then do some redevelopment pumping with our test pump to clear the well of sflt and abrasive parttcles in suspension. This process would save wear on your pump and establish the performance capability of the well. These procedures could be accomplished if the well discharge water was allowed to flow tnto the orc~ard and flood that field as has been done in the past. A cost sheet ts attached for your consfdertation. WELL #1 Jerry and I have reviewed the video and log on this well, and we feel that it will require some repairs, some rehabilftatfon and then redevelopment. The lip at 219 feet, and possibly the lip at 261 feet, should be carefully swaged back into conformity. This must be done with care because of the age and condftfon (and previous repairs) of the well. We strongly recommend the Hydro-Purge process be employed on this well. The video survey went to a depth of 975 feet, showfng perforations starting at 380 feet that were heavfly encrusted from 430 feet down. To open these perforattons at the least risk to the casing, the Hydro- Purge process would have advantage over any physical contact or shock method such as swabbing, sonar or jet, or blasting approach.

The Hydro-Purge process does provide pumping data, not to the extent of the development testing, but at least some pumping as opposed to the swabbing process necessary for Well #3. These procedures are also dependent upon being able to pump off from the well head and observe the pumpage. The curb drain approximately 100 feet up the street may offer the means to pump off. A cost sheet is attached.
