I’d like to hear your opinion and thoughts on earthquakes in Oklahoma and how it may affect the oil and gas industry.
These quakes are almost entirely limited to where water soluble formations are horizontally drilled and injection wells in the vicinity are utilized. The shale formations do not shoe these characteristics.
The largest culprit is the Mississippi lime in the northern half of Oklahoma and Southern Kansas.
This gives the entire industry a black eye!
Just my observation.
an interesting topic for a thread. I watch this link http://folkworm.ceri.memphis.edu/recenteqs/Quakes/quakes0.html which shows all recent quakes in our part of the country. There are certainly a lot of them in Oklahoma, not so many in Arkansas, Texas ect. Surprisingly there are not hardly any in Louisiana where there is a lot of injecting going on. Very few down in the Eagle ford area of Texas either. Arkansas and Missouri seem to be mainly along the New Madrid fault area. with another area north of Conway.do not know enough about that area to say anything about it. I think the key to earthquakes is the compatibility of the chemistry of the water you are injecting with the chemistry of the groundwater you are injecting it into.
Production and/or disposal wells located very near or directly on an existing fault line appear to have a significant link to some of the earthquakes in North Texas.
