Oil/water separator Aqueous Recovery Resources, Inc. (ARR), a specialist in oil/water separation, has introduced the Suparator system, new technology that incorporates a three-step separation mechanism that relies on basic physics and involves no moving parts or media. Water and oil enter the first compartment, where, ultimately, only water gets sucked out through an opening at the bottom. The design ensures that any amount of oil, even small traces, gets collected. The oil, still containing some water and chemicals, gets concentrated into a floating layer of considerable thickness, while water and chemicals migrate toward the interface and re-enter the water flow. The oil is then further concentrated to force water and chemicals out to yield an oil-only layer. The upper fraction of the accumulated floating layer gets skimmed off, isolating pure oil. Finally, this "dry"oil (typically less than 1% free water) is separated and ready for downstream refining or storage. The system makes use of the Bernoulli effectwhereby increased stream velocity in a fluid results in internal pressure reductiondynamically separating liquids of differing specific gravities. A number of valves are mounted across the fluid channel so that the major part of the flow passes underneath and a smaller portion passes overhead. Several "wings" are used to progressively shear off more oil and reduce water content. Since the interface layer does not have the same specific gravity as oil, dirt and other unwanted foreign objects are removed before they settle into the water tank and require detergents or maintenance. Since just 500 ppm of residual hydrocarbon remains in the separated water, the water can be reused immediately in oil field operations, while the separated oil contains less than 0.3% water and can be sold immediately.

Durable PCD bit
Atlas Copco Secoroc has released a new drillbit with advanced PCD technology that is significantly more durable than conventional diamond inserts. The new CaliberXD bit offers increased durability of the PCD inserts, and also features a tapered foot valve that is designed for deep hole applications. Configuration options include fishing threads, retrieval head and a QL shank.
