Conoco's average gas price from its Lower 48 operations more than doubled to $4.56/mcf from the fourth quarter. Diamondback, which operates in the heart of Texas's biggest shale field, saw average gas prices jump more than 21 times to $3.05/mcf from a year earlier. The combined company produced 1.32 Bcfg in the period, more than double Conoco's in the previous quarter, which helped offset the financial impact of lost oil production from the freeze.
