Abstract
Ionic exchange intensity in argillaceous reservoirs can be controlled by crown ethers. They inhibit clay swelling while aqueous solution fil tration and boost rock permeability. A bentonite clay swelling pattern in magnetised and non-magnetised wafer, and when adding trace quantif ies of cyclic oxirane oligomers into this medium, was studied. Concent ration ranges and an optimum content (0.005-0.01%) has been found for these ethers (cyclic polyethers based on propylene oxide) to minimise clay swelling.
