Description

Attempts were made to cause well Dixie Federal 45-14 to flow by reducing the wellbore pressure opposing possible producing formation. Such pressure reduction was accomplished by using a Magcobar air compressor to lift the water column out of the wellbore. Three series of efforts using this method were performed. The conclusions from these last attempts to flow Dixie Federal 45-14 were: (1) the massive water entry at 5820-5870 feet was shut off; (2) the compressor, with some help from the mud pumps, was able to virtually clear the wellbore of water above the point of air injection; (3) despite evacuating ... continued below

The possible benefits of temperature equilibration or other time adjustments within the prospective interval below 8000 feet may include eventual capacity to flow. This potential will be evaluated with future flow attempts; and (4) there is some small liquid entry somewhere between 6290 and 9022 feet which caused the air compressor to go through very long (3-4 hour) cycles of unloading and slowly re-filling the wellbore.
