The price of the fuels will come down if: (1) Kenya, or the land where Turkana is, has an oil refinery and its engineers are competent enough to refine aviation fuel. Bear in mind that Jet A-1 is only a modified form of household kerosene (2) Even if you don't have a refinery, oil exports mean increasing foreign incomes which, if well managed by government, would translate into infrastructural and social development and by extension, more supply of these fuels. Government would have to be careful about inflation, though. (3) Then again, officials at the top might just siphon revenues into their own pockets. Just look what they're doing in Nigeria (4) And so, in a nutshell, oil in Turkana is a blessing, but whether human foibles won't get in the way is the million dollar question
