This came to me from a reader.
49 acres of “We all Fall Down.”
The “Smackover” field in Navarro County represents an example of permitted H2S for EOR scheme that I find so worrisome. – the only confirmed example I have found so far.
Two producing wells at the site. Waste H2s is injected into Well #2 so that Well #1 can be re-opened. 500ppm radius for worst case doesn’t impact any roads, etc, so there is no trigger for public hearing. Application approved without opposition by TRC in 2010. 825 foot radius is just over 49 acres by my math.
note: these are not ppm levels being injected. these are percent.
APPLICATION OF O’ RYAN OIL AND GAS TO AMEND PERMIT NO. F-15381 TOALLOW DISPOSAL OF OIL AND GAS WASTE CONTAINING HYDROGEN SULFIDEGAS INTO A FORMATION PRODUCTIVE OIL E OF AND GAS AND FORAUTHORIZATION PURSUANT TO STATEWIDE RULE 36 TO INJECT FLUIDSCONTAINING HYDROGEN SULFIDE IN THE BURNETT-SLOAN UNIT WELL NO. B2 IN THE TROOPER (SMACKOVER) FIELD, NAVARRO COUNTY, TEXASO’ Ryan plans to inject a mixture of 46.3% H2S and 46.5% carbon dioxide (CO2) into the Burnett-Sloan Unit Well No. B2, between the depths of 9,294 feet and 9,410 feet, which includes the entire Smackover formation. This proposed injection will allow the Burnett-Sloan Unit Well No. B1 to be brought back on production, increasing recovery from the field.O’ Ryan plans to inject a maximum of 1,550 MCFD of H2S and CO2, with a maximum surface injection pressure of 4,500 psig. It is estimated that the average daily injection volume will be 1,400 MCFD.The 500 part per million (ppm) radius of exposure (ROE) for the subject well is 825 feet and the 100 ppm ROE is 2,020 feet. The radii of exposure are calculated based on worst case scenario of a injection wellhead blowout with maximum escape volumes and hydrogen sulfide concentrations. There are no public roads, residences or businesses within the 500 and 100 ppm ROE.Y’all are nuts.
As I’ve mentioned before, industry uses carbon disulfide in fracking so why not hydrogen sulfide? Those sulfides are such great solvents and it’s a good way to get rid of junk you don’t want.
They use H2s gas for enhanced recovery in Canada too.
