anything new from gassed?, page-8

You crack me up Gassed - had you not responded with an over bolded post I really would have been disappointed.

But here's an idea on some new thinking that's actually be around for a while now.

We know that our gas has a high CO2 content. We also know that we have plentiful water in our tenements (but fracking is water intensive).

What if CO2 was used in the fracking process instead. We need to separate CO2 anyway - maybe we could put it to good use. Statoil and GE are studying this (GE says it will invest $10B in energy technology by 2020). Also looking at what effect on the type of proppants that would be used (a major cost factor). Not talking about using LPG gelled frac ahla the company "Gasfrac"

By way of example

So the liquid CO2/sand mix pumped in, then liquid CO2 changes to gas and is recovered along with the methane and sent to gas plant to be separated - sales gas into the pipeline and CO2 liquified and back to use in next frac. Kind of a closed loop system.

All about getting best NPV (lower your cost and increase your recovery)


Of course maybe the most obvious - use a natural gas powered rig instead of diesel.

Cummins/Westport doing the hard yards on that - happening now in US - on the roads for Class 8 Trucks now (both LNG - yes LNG although there are questions on that - in addition to CNG/Propane/LPG whatever its called).


And then of course is all fracking improvement with fracking itself like:

HiWAY frac from Schlumberger (mentioned it before) where they add "fibers" to the proppant mix to create (infinite - so they say) conductivity (flow)

Rapidfrac from Halliburton - a completion technology which is centered on accurate fracture placement and has big cost savings potential. The 2 min video is good overview - but it is a large file - 80MB to download.

Probably considered as a competitor to RapidFrac is Baker Hughes and their ball drop method (also mentioned before).


All these things reduce our F&D costs for when the time comes to develop our tenements.
