I talked about Schlumberger Hiway fracking a long time ago. That posting has been one of my most visited sites; this should be of interest to those looking for an update.
So how does Hiway work?This is one of the better articles on fracking I have seen in a long, long time, updating the technology now being used, in a language I can understand.
Hodenfield, who grew up in North Dakota where the Bakken field is at the centre of the U.S. shale gas boom, brightens at the opportunity to explain a process that adds a proprietary fiber to the traditional sand and fluid mix, and uses a "pulsing" system to send globs of the fiber in between each injection.
The dissolvable fiber globs create more effective channels for the gas to flow, and the pulsing rhythm can be made to match the geological structure of the rock, also pushing the sand deeper into the cracks and resulting in more effective openings that conduct gas better for every liter pumped in.
Hiway is not the only new technique on the scene as oil companies look to use fracking to reach more lucrative oil as well as gas.
Schlumberger and other innovators are also using sophisticated seismic techniques, combined with data from pilot wells, to reduce the number of fracks along a drill pipe and target only the "sweet spots" in the field.
Go to the link; there's a lot more information there.
A huge "thank you" to a reader for sending me this link.
