Diamondback Energy raises full-year capex guidance to $3.95B-$4.0B

The upward revision is modest in absolute terms, but it signals that cost pressure or scope creep is creeping into shale budgets even at a large, disciplined operator.

The open question is whether this is a one-off adjustment tied to specific activity or the start of a broader pattern across peers as service costs and well designs evolve.
