The problem.I have spent some time thinking about the CO2 problem. The actual problem is that CO2 dissolved in water becomes an acid. This acid will and does dissolve copper oxide. To keep cO2 dissolved in water a pressure of at least 5 atmospheres must be maintained at room temperature. When the pressure is lowered the CO2 rapidly comes out of solution and the dissolved copper oxide is released,, plugging everything up. A column of water 300 ft deep will easily produce enough pressure at the bottom of the well to keep the CO2 in solution. The problem occurs when the solution is being pumped out. At some point we were shown a picture of a pump covered in copper oxide. This should be a solvable problem. Let's hope management are good problem solvers.
