Looks like 2 to 6 months if I understand this correctly:

Depending on the depth of drilling required and the type of drilling method used, a standard oil well can commonly advance from drilling to the beginning of production for an oil company within one to three months...

if horizontal well drilling is used instead of standard vertical drilling, this can often double the total cost of drilling and the time required to move from drilling to production. On the positive side, however, horizontal drilling can potentially enable the oil producer to recover up to four times more oil than could have been accessed with conventional vertical drilling.

Got this from:
