RE:RE:RE:VLE has the option to tap into Yam-1Valeura and Statoil as 50/50 partners negotiated what the completion and testing program would consist of on the deep play so that has been determined and in the process of being implemented (4 intervals with 2 frac stages each). VLE can't just decide to do another on the deep now.
VLE owns 100% of the shallow part of the well so they could conceivably do a shallow completion on their dime but that would have to be discussed with STO and incorporated as part of the plan. As this well is all about the deep and it wasn't mentioned in the news release I suspect they opted not to do that (they could do it at a later date if it is prospective).
4 test intervals will only cover a small portion of the net pay as this is an exploration well. They are testing certain areas to economically determine what they have before determining next steps (e.g second well, yest different parts of the pay, modify completion techniques etc.).
