IMO, they don't have the resources to do a buyback if they want to work at their capital expenditure program, it'smore important at this time for them to direct their resources at increasing production, paying the dividends and interest on debt. If and when they do have some spare change (which I think is a fair ways off) they could do a buyback which as you say would tend to raise the share price and at the same time reduce the amount spent on dividends.
