Two operating injection wells, just outside of the moratorium area, are about 8 miles from some of the quakes.
It found small seismic events involving "a very limited number" of injection wells, but the long-term effects of the growing number of wells wasn't known.
The quakes prompted state officials in January to order four fluid injection wells in the eastern part of the state to be "indefinitely" prohibited from opening.
While Chesapeake Energy claims that there is no relationship, researchers have observed that the earthquakes in Central Arkansas declined since two injection wells in the area were shutdown.

The Chinguetti development will include six production wells, four water injection wells, and a gas injector well, attached to a permanently moored floating production, storage and offloading vessel situated in about 800 metres of water.
In Arkansas, known for the rich Fayettevile Shale reserve, a drilling moratorium on new injection wells has been established as scientists believe that the large number of earthquakes recorded in the region may been a result of fracking.

As of March 28, the Bureau of Ocean Energy Management, Regulation and Enforcment (BOEMRE) of the Department of the Interior had received 31 deepwater drilling permit applications for offshore drilling activities like water injection wells and drilling from a fixed rig that were still allowed under the moratorium.
Further, although thousands of CBM wells are fractured annually, EPA did not find confirmed evidence that drinking water wells have been contaminated by hydraulic fracturing fluid injection into CBM wells.
In its review of incidents of drinking water well contamination believed to be associated with hydraulic fracturing, EPA found no confirmed cases that are linked to fracturing fluid injection into CBM wells or subsequent underground movement of fracturing fluids.
Carbon dioxide can sometimes be sold to oil companies for injection into partially depleted wells, in order to force more petroleum out of them.
Nine banks have already agreed to take the injection, including Bank of America, Citigroup, Wells Fargo, JPMorgan Chase, Morgan Stanley and Goldman Sachs.
