UPDAYE MAY 19 2015 Royal Dutch Shell is selling off its French LPG field (butane/propane)-they also cut their global oilfield exploration (seismic) budget by $1.5 billion….they will probably focus on Brazilian deep water LNG exploitation….tisk tisk tisk-they need to get solar and wind wound.
Central Valley’s growing concern: Crops raised with oil field water
Last summer in 2014, the New York Times reported that Chevron sells it’s oil filed waste water for farming in California.
http://www.nytimes.com/2014/07/08/us/california-drought-chevron-oil-field-water-irrigation.html “About 760,000 barrels of water a day are produced at the Kern River oil field — compared with 70,000 barrels of oil — and half of the water goes to the Cawelo Water District.”
I had been concerned that the fracking related waste water called “produced water”, which has a high salinity, was being used to de-ice the roads in Pennsylvania. I feared the run off could get into soil and water supplies, and risk our “food” supplies. Who wants to eat produce that is grown with contaminated “produced” waste water?
But the most recent story here in April 2015 got my attention (I boldfaced for emphasis)…
http://www.bakersfieldnow.com/news/local/Oil-wastewater-used-on-Kern-County-crops-298949201.html?mobile=y says “…the general manager of the Cawelo Water District, says they have been buying half a million barrels of water from Chevron every day for about 20 years.
Then they dilute it with fresh groundwater.
“The farmers here rely on this water. In years like this, we’re trying to keep everything alive at this point,” he said. “It’s a very good water supply to have.”
It’s supposed to be a win-win. For every one barrel of oil Chevron produces, another 10 barrels of the salty water come up with it.
Ansolabehere tells us this technique is fairly unique to Kern County, because the salt in Chevron’s water is particularly tame (less salty) in this area.”
So I’m reading this and thinking….the saltier the brine, the more radioactive it is….ooops-Chevron sells less radioactive water to the farmers?
When NORM (normally occurring radioactive matter) gets disturbed and mixes with mankind’s-introduced-fracking-chemicals, it then is transformed in a new regulated state called TENORM (technologically enhanced NORM). I hope to baby Jesus that TENORM is only found in flowback water and not produced water. But then again I keep coming back to those haunting words……the more saltier-the more radioactive…dang!
The Difference Between Flowback & Produced Water:
Flowback is a one time stage that occurs after all the water, sand, & chemicals are pushed down into the ground (frack) to mix with the bowels of earth’s heavy metals, radon, arsenic, NORM, natural formation (salt) water, and other nasty constituents. All that TENORM ladened water flows back up and needs proper (regulated) disposal (to later cause earthquakes). Depending on the geology, some of the “frack on crack” flowback gets left down there to risk other ground water supplies.
Whereas Produced Water will have flowback in it (just initially? how long?), but is basically comprised of the old oceans beneath us that get disturbed when they drill/frack for fossil fuels. These high salinity waters come up (not by choice) and this is what reckless farmers like in California want to farm with?
Chesapeake showed three types of produced water quality levels of Total Dissolved Solids……
“Brackish” (5,000 to 35,000 ppm TDS) which brackish water in Australia is where Shell is planning to be the world’s biggest producer of liquefied natural gas as was reported by the Australian.com.au.
IESC reported…”Co-produced water is generally brackish, with salinity levels ranging from about 300 to 10 000 milligrams per litre (mg/L). By comparison, the salinity of water supplies for Australian towns can range from less than 250 up to about 1000 mg/L ,”
“Saline” (35,000 to 50,000 ppm TDS)
“Brine” (50,000 to 150,000+ ppm TDS)
But in this article…http://www.circleofblue.org/waternews/wp-content/uploads/2010/08/prodwaterpaper1.pdf a very telling, a very chilling description in the executive summary is as follows (I boldfaced for emphasis)….“Produced water characteristics and physical properties vary considerably depending on the geographic location of the field, the geological formation with which the produced water has been in contact for thousands of years, and the type of hydrocarbon product being produced. Produced water properties and volume can even vary throughout the lifetime of the reservoir. Oil and grease are the constituents of produced water that receive the most attention in both onshore and offshore operations, while salt content (expressed as salinity, conductivity, or total dissolved solids [TDS]) is also a primary constituent of concern in onshore operations. In addition, produced water contains many organic and inorganic compounds that can lead to toxicity. Some of these are naturally occurring in the produced water while others are related to chemicals that have been added for well-control purposes. These vary greatly from location to location and even over time in the same well.”
I recall a conversation with a RRC guy who said that the wet drilling mud is something that adds beneficial moisture to our dry Texas soil….I didn’t want to know any more …’nuff said. My gut is that some of your Texas produce may have been grown in TENORM drilling mud.
But before I end this blog about produced water, I must add that there are also issues with spills at these drill sites that cause the metals in the dirt to bind and leach out and make the spill to be even more toxic because of the COLLOIDS. So the question begs if you take produced water and add it to dirt, aren’t you inviting a heavy metal concert to your diner table?
Why not instead create your own water out of thin air instead of dredging it up from the bowels of the earth?
SO WHO ELSE IS GOING TO GET A MOTHERLOAD OF PRODUCED WATER THAT THEY COULD FEASIBLY SELL TO DROUGHT HUNGRY FARMERS? (read on)…
NY Times reported that recently Royal Dutch Shell bought an LNG company called BG and plans to drill for natural gas in Brazil and take over an LNG processing plant in Queensland. On a side note,“BG has a contract to buy L.N.G. from a facility called Sabine Pass on the Gulf of Mexico, owned by Cheniere Energy.”
I blogged about how globally that type of gas yields a mother-load of produced water in relation to the actual gas you get…which makes me think they are getting into the selling nasty water business?
Coal Bed Methane represents only 2.4% of global gas production, yet accounts for an estimated 67% of the global ‘produced water’ that gets disturbed, brought up, and needs to be disposed of properly (to later cause frackquakes).
http://www.bloomberg.com/news/articles/2015-04-08/shell-to-sell-twice-as-much-lng-as-exxon-chevron-after-bg-deal ..”The deal gives Shell access to BG’s Australian project to produce 8.5 million tons of LNG a year from coal-seam gas. “
