If its Angus water it would seem it may have enough salt in it to be able to walk on!!!....lol
"What are your plans for the water reinjection well at Brockham?What we’d like to do is to discuss water reinjection. We’d like to do more studies internally. We have done it in the past. We may conceivably do it again. We would do it only on the basis that there would be negligible risk of any significant pressure problems on the hole. Over the 20 or 30 years that the Portland has been worked at Brockham, about 300,000 barrels of fluid have been removed. So,it’s a depleted reservoir that could be available for injection. Injecting water would clearly allow us to increase the recoverable oil and would potentially solve problems in terms of disposing of water elsewhere.
We haven’t made any definitive planning or application for that purpose. But what I will say is this: water disposal for the onshore industry is quite an issue. The salinity of formation water is incredibly high. The salinity is of such a concentration that even using the most sophisticated filtration techniques it is almost impossibly expensive to clean it up. And when I say clean it up, we’re not talking aboutsome heavy metal. It’s just the salt. So,you get to a point where we do what we do now. Rightnow, the water has to be trucked several hundred miles and then burnt because there is simply nothing else that we can do with it. We’re at a loss that we can’t get environmental permits to inject 2,000 meters below the surface, 1.5km away from the nearest water table that anyone conceivably uses and yet one gets this great resistance that,somehow,we’re poisoning the environment. And yet we truck it miles and miles and miles up country roads and motorways and then it gets burnt. We’ll consider it [waterreinjection] but we haven’t got any application in to do it yet. Do you need water reinjection to get the Portland flowing at reasonable rates?My understanding is it unquestionably increases recovery, yes."
