Multi-stage fracturing of horizontal wells in the Bakken

Packers Plus Energy Services Inc., Calgary-based company, says its unique technology can deliver precisely-controlled fracs along a horizontal wellbore at an affordable price. “Without our StackFrac system, the Bakken formation in southeastern Saskatchewan would still be uneconomic for the most part,” says Dan Themig, president of the seven-year-old private firm. Producers had already attempted straightforward …

Large sheets of Carbon nanotubes produced

Nanocomp Technologies of Concord, is producing sheets of carbon nanotubes that measure three feet by six feet and promising slabs 100 square feet in area as soon as this summer. The first applications will probably be as electrical conductors in planes and satellites to replace copper wire and save weight. Saving weight would save fuel. …

Nanoemulsion vaccines could be effective against smallpox and HIV

A novel technique for vaccinating against a variety of infectious diseases – using an oil-based emulsion placed in the nose, rather than needles – has proved able to produce a strong immune response against smallpox and HIV in two new studies. The results build on previous success in animal studies with a nasal nanoemulsion vaccine …
