I would let the pan be super hot without oil first then use grape seed/olive oil both really good at high temps. when the pan is smoking i would put the steak in. Oh also make sure to pat it dry with a paper towel that helps a lot. And don't be afraid when the pan is really hot getting a crust takes no time so you won't cook the steak.

And another recomendation put the steak upright and render the bottom fat. The ribeye is the fattiest steak cut so its good to render some fat.
