IDENTIFYING CLAY SWELLING PATTERN

This study testifies mathematically the dependance of swelling on time for the clay sample taken at a gas well in Divjaka at the depth of 3080 m as well as the Perrenjas clay. Clay swelling at water contact is a parameter which is very important in the areas where clay is used. Swelling is measured under the impact of various solutions with a special apparatus. In order to give the practical value of clay swelling pattern,clay swelling size measurements that we have defined are calculated mathematically to determine which pattern approximates factual swelling. The results showed that the equation is linear.
