Polymer Chemistries Provide Long-Term Scale Prevention

摘要

Scale formation plagues the oil and gas world. It can be caused by the combination of several different parameters such as brine waters, dissolved solids, pressure and temperature. These components can form a precipitate, especially in situations with incompatible waters. These precipitates coat, block and otherwise cause problems throughout the extraction and refinery processes. It is possible for a well to go from great production to zero in one day. A classic example took place in the Miller field of the North Sea, where production was near 30,000 barrels per day and dropped to zero in 24 hours. This reduction was caused by scale from mixed waters.
