Since pigging operations were scheduled to continue, operations were delayed until a resolution for treatment and discharge of the contaminated pipeline fluids could be found. CETCO Oilfield Services was selected as the solution! As operations for the hydrotest and pigging project were being delayed, timely mobilization and setup of CETCO Oilfield Services equipment were a necessity. CETCO Oilfield Services was onsite and setup immediately, successfully completing the project within the pipeline company’s schedule. The table below left illustrates CETCO Oilfield Services effective treatment of the hydrotest fluids.
The company expected approximately 67,000 barrels of fluid to return from the pipeline. In order for proper pig runs to occur, it was necessary to run the pigs at a rate that would produce approximately 1,000 gallons of water per minute, or between 20 and 25 barrels of water per minute. Furthermore, since smart pigs were incorporated into the pigging operations, there could be no operational downtime during pigging in order to achieve the maximum performance from the pigs. CETCO Oilfield Services hydrotest water treatment capabilities were the key in making this project a success, as the pipeline fluids had to be continuously treated and discharged during the pigging operations.
CETCO Oilfield Services supplied the personnel and equipment capable of handling such a largescale project. CETCO Oilfield Services achieved water treatment rates of over 20 barrels per minute. The entire project was completed successfully, with CETCO Oilfield Services treating and discharging 68,200 barrels of water into the river.
