Paper: Evaluating Present Equipment To Obtain Better Water Quality

Properly prepared produced water can help eliminate the millions of dollars spent yearly on injection and disposal wells. Large holding tanks and wash tanks are often used as oil separators and water polishers throughout ::he industry. Evaluating the effectiveness of these tanks can be accomplished through the interpretation of a retention study and by reviewing analytical data derived from oil parts per million and millipore filter analyses. The flow characteristics of the tank and the tank's effectiveness in removing oil and solids will aid in determining the type of internal design needed for better equipment utilization. This paper will deal with three ways of modifying water holding tanks and wash tanks economically to provide better water quality. The effective methods used in treating reclaimed oil and solids to provide saleable oil will also be presented.
