I would expect H2 to be first up for rework, MB has stated it will be acidized and well tested, acidizing is a well stimulation technique used in oil and gas wells to improve production by dissolving formation damage or enhancing the natural permeability of the reservoir rock. It involves pumping acid solutions (such as hydrochloric acid or hydrofluoric acid) into the wellbore and surrounding formation to open up flow channels, it can improve production by a factor of ten, probably that is too much to hope for, we know H2 well tested at 30 bopd so a factor of 5 improvement would be a good result.
Keep in mind MB stated during the LSE interview (9m 03s) that at 30 bopd H2 was only marginal commercial in winter, the reason for this would be, during the harsh Mongolian winter the oil stored at the well site must be kept warm so it can be easily pumped into the tanker, we really do not need a huge increase to make H2 commercial but obviously the more the better.
During the LSE interview he also mentioned re-perforating so they seem convinced oil is there in commercial quantity but some issue, either well damage resulting in sand and fines blocking/ clogging up the perforations or even poor perforating is to blame for the low 30 bopd well test, essentially the oil is not getting into the wellbore, if they are right then acidizing/reperforating could easily result in a commercial rate well test.
