1)an oil "show" can be anything from oil extracted from the cuttings and examined under a microscope with a black light (yellow flouresence) to free oil coming up with the mud. a shaker is just a vibrating screen used to separate the drill cuttings from the mud. i assume "that oil shows over the shakers" means that free oil was visible. 2) i dont think 20 frac stages means that they are drilling longer laterals because they already drill the maximum lateral length within the 1280 spacing unit. separating the wellbore into smaller segments results in more efficient frac'ing(better flow path from the natural fractures to the wellbore). evidently, if they just use one frac stage, the gel and sand will tend to propagate in one area, leaving sections of the well unstimulated.
and imo, the jury is still out as to whether more frac stages will result in better economics. 3) i think #1) answers this ?
