Dutch gas company uses bubbles
The Dutch natural gas company NAM is planning to use soap to recover the last remaining gas from nearly-exhausted gas fields.
8 November 2008
THE NETHERLANDS - In the past, the cost of removing the remaining gas was too high.
The new technique was developed in the United States.
Dozens of litres of environmentally-friendly soap are injected into the gas field, creating bubbles at the bottom where there is a layer of water. The bubbles push the gas out.
The technique is expected to produce 10,000 to 250,000 cubic metres of gas.
