In an effort to increase the flow rate through a well in the Gulf of Mexico and ultimately unload the well, a major operator required a means to increase the flow rate from 500 barrels of total fluids per day to at least 2,000 barrels per day.
The operator required a system that could simultaneously increase the flow rate through the well while ensuring the resulting wastewater met strict overboard discharge criteria.
Additionally, it was stipulated that the system had to be able to handle a minimum of 2,000 barrels of water per day in order to unload the well successfully.
After two weeks of trying to increase the flow rate without success, the operator contacted CETCO Oilfield Services to deliver and install a temporary flow back water management system to increase the flow rate and ultimately unload the well.
Assessing the needs of the operator, CETCO Oilfield Services devised and deployed its Hi-Flow® technology to act as a temporary flow back water handling system.
Once the fluids from the well were sent through the Hi-Flow vessel, the flow rate immediately increased, meeting the rate required by the operator to unload the well.
The temporary Hi-Flow flow back system took the total fluids from the well until it was successfully unloaded and sent back to the platform.
The fluid was taken from the wellhead through a choke manifold and into a low pressure separator. The water was then sent through CETCO Oilfield Services temporary flow back system consisting of a Hi-Flow IFV 2000 vessel and a small bulk carbon vessel to clean and restore the fluid to the required overboard discharge level.
Water containing solids, minerals, and oil products was arriving into the separator at an average of 15,000 ppm. Following treatment in the separator the flow back fluid was pumped into the Hi-Flow system at an average level.
