What’s the difference between re-fracking and water flooding an oil well?
To be ‘refracked’ wouldn’t it have to have been ‘fracked’ first?...................
Water flood is a continuous enhanced oil recovery method where injection sites on the outer edges of the field have water injected to push more oil into existing producing wells more towards the middle.
Hydraulic Fracturing, regardless if the first time, or a repeated process on an older well, is pushing water, sand and some chemicals down the production well to create cracks in the formation with the sand left to hold the cracks open. The water is removed and the oil/gas flows out through the cracks left open.
Each can be more involved and use different materials, but they are very different processes.
The environmental whack jobs protest re-fracking and cheer when the well gets flooded.
