$this->bbcode_second_pass_quote('', 'M')r. Steinsberger, now 54, called the experiment “my slick-water frack.” It was the first commercially successful use of sand, water and chemicals, pumped into the shale under high pressure, to break open the rock and unleash the natural gas trapped inside. It was the beginning of modern fracking.
this is classic reporter not knowing the subject they are talking about.
slick water when it was first used by Steinsburger was just the original frack fluid sans large amounts of gel. As a consequence, it was basically water and a bit of soap which is exactly what was used for fracks back in the eighties and nineties prior to gel polymers and low vis fluids. If you don't believe me do a bit of research. I know I'm right....I was there when we used water with little in the way of additives to do clean up fracks.
And when they say "It was the first commercially successful use of sand, water and chemicals, pumped into the shale under high pressure, to break open the rock and unleash the natural gas trapped inside"
slickwater does not have sand in it. In the frack described by Steinsburger back then he was not using any propant just the regular fracking fluid with less and less gel and more water and no where near the pumping rates of modern fracks. The fact it is "slickwater" means it has very little in the way of "chemicals", basically just soap suds to reduce viscosity. It wasn't until much later that other chemicals were used to lower viscosity and help penetration which is when slickwater fracs really came into their own. Originally they were mainly used to lower costs (gels were expensive) but through time with the introduction of friction reducers wells could be pumped at much higher rates which allowed for larger sized fracks and greater IP rates.
Now they may be right that this was the first time water was used without gels as a fracking fluid in shales, but it had long been used without gels for carbonates and sandstone reservoirs both to clean up damage zones as well as in enhancing permeability in tight reservoirs. It was generally avoided in shales in the early days due to worries about the prescence of smectites (swelling clays).
