| Title: |
Down hole separation can be used to reinject CBM-produced water |
| Text: |
"Down Hole Gas/Water Separation: Down hole separation utilizes specially-designed pumps that separate produced water and gas by centrifugal or gravitational forces within the well bore or in the subsurface formation. These pumps can be used to lift fluids or reversed to inject fluids. Natural gravity separation occurs within the well as water settles to the bottom and the gas rises to the water surface. Gas is extracted while the remaining water is pumped into a deeper receiving formation through a separate injection line, provided that the down hole pump, or hydrocyclone, is carefully located at the correct depth in the well. This system requires that there be an adequate receiving formation with adequate separation between it and the producing formation. Only a small amount of produced water, about 3%, actually reaches the ground surface." (For benefits and problems with the process, see the source document) |
