Every hour spent waiting on cement costs money. The Automated Curing Chamber helps optimize well cement performance by curing cement slurry specimens under simulated down-hole conditions, producing cubes for compressive strength testing. By helping engineers determine how quickly a cement system develops compressive strength, it supports slurry designs that reduce "waiting on cement" time and get drilling going again.

The Garrett Gas Train is the most widely used portable instrument for determining the concentration of soluble sulfides and carbonates in drilling fluid. Mud filtrate is acidified inside the gas train, converting all sulfides to Hydrogen Sulfide or all carbonates to Carbon Dioxide. The gas train then separates the gas from the liquid and an inert carrier gas transports the gasses through the separate chambers. In chamber three, the gas is passed through a Dräger-Tube™, which responds to Hydrogen Sulfide or Carbon Dioxide by darkening along its length, showing the concentration.

The OFITE Garrett Gas Train consists of a transparent train, pressure regulator assembly, Carbon Dioxide and Nitrous Oxide cartridges, Dräger-Tubes™ for sulfide and carbonate detection, and a convenient carrying case.

OFITE has designed an HTHP filtration cell with safety in mind. This modular design is much safer and more convenient. The two-piece cap is threaded, and cannot be opened while the cell is pressurized. And interchangeable caps make it easy to reconfigure the cell for testing with different filter media (filter paper, ceramic disks, or cement screens) with a single cell body.

The Production Screen Tester is designed to test flow-back of completion fluids on the rig site. It is no longer necessary to ship fluid samples back to the lab and delay the completion operation for days or weeks. Field fluids can be tested in real time with samples of the actual production screen being used down hole. The PST now makes it possible to determine if the fluid remaining in the annulus will flow back through the production screen.
