To maximize the recovery of hydrocarbons from a reservoir, several methods can be implemented after the natural depletion stage is over. The secondary methods which comprise water or gas injection help in maintaining the reservoir pressure to ensure hydrocarbon fl ow to the production wells. The recovery factor at the end of this stage often remains below 35% of the Oil Originally in Place. Tertiary methods are then developed to overcome this issue and reach recovery factors above 60%.

Polymer fl ooding belongs to chemical enhanced recovery; it is a well-known method (over 40 years of commercial application) with low risk and application over a wide range of reservoir conditions. It consists in dissolving polymer in the injected water to increase its viscosity and to improve the sweep effi ciency in the hydrocarbon reservoir.

SNF has developed a range of standard Polymer Injection Units (PIU) to facilitate polymer injection test, pilot and modular implementations. Units are based on standard 40 feet high cube maritime containers for easy transportation. The unit includes all equipment involved in the polymer solution preparation and injection. The unit allows a quick installation and a quick start up time. As this equipment is available as standard units, the manufacturing time is short and the costs are optimized.

The Polymer Injection Unit range declines as follow:

*Maximum flowrates varies with polymer solution concentration

Reference Purpose CapacityCompact PIU Injectivity test, SWTT 3,000 bpd @ 1000 to 3000ppm

PIU 100 Pilot, small injection fl owrates 9,000 bpd @ 1,500ppm*PIU 300 Pilot, medium injection fl owrates 30,000 bpd @ 1,500ppm*PIU 600 Pilot, high injection fl owrates 60,000 bpd @ 1,500ppm*

The FLOQUIP PIU can be installed or removed very quickly under any climate. Here a top skid for big bag storage is being installed.

FLOQUIP PIU COMPACTStandalone unit designed for injectivity testsA typical injectivity test on the fi eld will last from a few days to a few weeks. The FLOQUIP PIU COMPACT has been designed to simplify and accelerate the implementation of these injectivity tests.

The FLOQUIP PIU COMPACT fi ts in only one 40 feet high cube standard maritime container which makes it easily transportable over long distances, by ship, train or truck. And all the equipment inside is securely fastened during transport. The FLOQUIP PIU COMPACT is designed for onshore fi elds and safe area.

The polymer solution can be diluted at low or high pressure depending on the existing water injection configuration on the field.

The availability or not of high pressure water on site will modify the skid layout as well as the size of the HP pumps needed for the injection. The two graphs below summarize the different confi gurations. The rest of the skids and their equipment is not modifi ed. The capabilities are not modifi ed either.

BASIC STANDARD SKID DESIGN

To make down powder polymers you need to dilute it in resonably clean water in abscence of oxygen and let it mature at least for 45 mn. Then the concentrated mother solution is post diluted to the end users specifi cations and injected in the wells. The necessary equipment can be reduced to the 10 items listed below. Depending on the injection capacity required these can be contained in 2 skids or more.
