The decline in productivity in mature gas fields is often attributed to liquid loading but in reality it may be a result of salt deposition which can have similar consequences. The phenomenon of salt precipitation is gradually increasing and is becoming a serious issue in the North Sea.During gas production the reservoir brine will evaporate leading to an increase of dissolved salt concentration. Once the solubility limit is exceeded salt precipitation occurs which can have a detrimental impact. Salt precipitation results in a decrease in porosity and ultimately in a decrease of gas...
