Posted earlier:
At least three EOR pilot injection projects in North Dakota, one in the Madison and two in the Bakken are being proposed, from the September, 2019, NDIC hearing dockets (the following are cases, not permits). This is one of them.
- 27926, NDIC, McGregor-Bakken, to review the pilot injection project order
authorizing Liberty Resources Management Co temporary authority to use
certain wells located in sections 8/17-158-95 as injection wells for EOR
pilot project, Williams County
I'm re-posting this one because a reader sent this shortly after I posted the above:
Brief follow up to the EOR test project that Liberty Resources is doing in conjunction with several other entities, including NETL (National Energy Technology Laboratory).
Following are quotes from NETL's site "netl.doe.gov/node2078' ...
Title: "Bakken Enriched Gas Enhanced EOR."
Project started Nov. 2018 ... ending (field test?) May, 2019.
Max injection rate 2 MM cfd (2 million cfd ... modest amount)
By May 7, 2019, 130 MM cubic feet injected total ... again, modest amount of "rich" gas injected into four (4) wells during six (6) injection periods.
Key Observations:
" ... ability to inject rich gas has been demonstrated ..."
" ... injected gas can be controlled and has been contained within the DSU"
"Modeling predicts incremental oil recovery may exceed 25%."
Project ends 5/31/2020.
It would appear that in the crucial "real world" setting, Liberty has successfully demonstrated that when injecting a propane and ethane enriched gas stream (along with the cheaper, less effective methane),
the injections can be monitored, controlled, and contained.
The future ramifications of this are impossible to over state.
There is a short, graphic rich pdf from Liberty describing all this from last year's WBPC.
There's a bit of irony here. If I remember, I will come back to this. The Bakken is full of surprises.
