System enables use of fracture flow-back water
The GammaFRac System now on the market is suited specifically for hydraulic-fracture stimulation of shale-gas wells.
The slick-water system makes feasible (1) the use of returned frac fluids (flow back) and produced formation water in subsequent fracture treatments, and (2) eliminates the need to dispose of most fracture flow-back water. The system does not require application of water purification procedures to prepare the flow back for use as source water for preparing fracturing fluids. The four constituents of the fluid package are:
• WFR-3B salt-tolerant nanoparticle friction reducer. The patented additive is a liquid polymer that works in brines up to 12% NaCl, minimizes damage and fluid imbibition, and is designed especially for use in shale formations. The firm says that use of the friction reducer decreases wellbore friction pressure by 50-75%, which permits a reduction in wellsite hydraulic horsepower requirements, leading to decreased well-location footprint.
• Iron control polymer. ICP-1000 is a new iron control technology that chemically maintains the iron in fracturing fluids contacted by the formation in the reduced-valence state and helps prevent precipitation of iron compounds.
• Super TSC. This scale-control additive simultaneously protects against three types of scale precipitate: carbonate, sulfate, and iron-based scale depositions.
• KR-153SL biocide. This is an environmentally responsible, aqueous biomass control agent that delivers quick kill and degrades rapidly in the surface environment. The additive controls sulfate-reducing bacteria and controls slime-forming bacteria.

Rugged module for oil field operations
The new bCOM2-L1100 rugged COM Express board is designed specifically for harsh, space-constrained environments in oil and gas operations.
It features an Intel Cor2 Duo processor operating at up to 2.26 GHz and up to 4 GBytes of soldered DDR3 SDRAM. Soldered components help improve reliability, the firm notes.
The bCOM2-L1100 provides protection to ensure reliable operation in applications that are subject to shock, vibration, and extremes of temperature (–40° to +85° C.). All components are soldered to the board for optimum reliability, while mechanical standoffs provide a high degree of insulation from external forces. Available in a standard version for benign environments, the board is optionally available in extended temperature variants and with conformal coating.
