The package includes 9.6 million cubic feet of natural gas per day and 22 barrels of oil per day of current production.
Cash from the sale will be used to fund Comstock’s drilling programme in the Haynesville Shale play where the company plans to add a second rig next month.
"This sale strengthens our balance sheet by providing additional liquidity and helps fund our Haynesville shale drilling program," chief executive Jay Allison said.
