The answer to that  question  is yes but we don't know yet how big the field is.  They will continue to expand the field drilling off sets of mitchels wells. The formtion of sandstone is down around 4200 feet. Is The formation getting thicker as we step out each well? If so it may hold more oil than M#4 . If its running thicker, drilling will indicate that we will reach the formation sooner. This called " running high" which is good. They should be able to step out new wells until the formation peters out and to thin to risk drilling  a dry hole. This pool could provide Treaty with 8-10 wells or more. The reservoir  of oil may be calulated by some math which would give the "proven reserves ". Thats what oil companies want. Treaty is getting close .
