EAGLE FORD SHALE

EAGLE FORD SHALE SUMMARY

62,000 net acres

Current operated rig count: 2

– Added a second rig in late July that will focus solely on multi-well pad development (3 – 6 wells per pad)

Operated wells producing: 50

Operated wells currently drilling: 2

Operating wells completing: 2

Average completed well cost: ~$6.5mm

– Multi-well pad drilling expected to reduce well costs by $500,000 - $600,000 per well

400’ down-spacing results continue to reinforce the concept, resulting in ~500 identified undrilled locations remaining in COG’s 100% owned and operated Buckhorn area

Recently completed an extended lateral well (8,000’+) with a 24-hour peak rate of ~1,130 Boepd and a 120-day rate of ~1,100 Boepd
