Foam cement is a versatile, low-density cementing system used in many oil-well applications. It is commonly used for low fracture gradient or lost circulation problem wells. The formulation is unique compared to other oil-well fluids because it uses three phases of matter. The solid phase consists of cement and other dry additives. The liquid phase is mix water and any liquid additives. And the gaseous phase is, in most cases, nitrogen (N2) gas.

Adding nitrogen gas to a cement slurry dramatically reduces the density while using the same amount of mix water. Because no extra water is used, foam cement develops sufficient mechanical strength for well-bore application while improving the bonding characteristics. As the temperature increases down hole, the nitrogen gas expands, pushing the foam cement against the formation and casing and creating a stronger bond. Despite the added benefits, expansion also creates challenges for laboratory testing.

Any lab that runs high-temperature, high-pressure filtration testing has to be concerned with safety. Heated and pressurized test cells, if handled improperly, can injure people and damage equipment. Yet if they are handled properly, they are as safe as any other equipment. That is why OFI Testing Equipment offers several devices specifically designed to help laboratory staff correctly handle HTHP filtration cells.

The first thing you need to safely work with HTHP filter press cells is a suitable stand. Our device (#171-190-028) is designed to hold a cell upright for assembly, disassembly, or cooling. The cup at the top prevents the cell from tipping, and the open space below provides plenty of room for a valve stem. And for extra stability, the entire stand can be attached to a countertop or workbench.
