NITEC completed a storage optimization study for a large storage field in Kentucky, initially with over 150 old vertical wells, 135 BCF Total gas and 730 MMcf/d peak deliverability. The history matched model was used to evaluate replacing old vertical wells with horizontal wells, surface gathering system improvements (12 branched/looped lines), and additional compression power. Currently, the field has 13 horizontal wells, increased deliverability to 1,030 MMcf/d, and improved working gas to total gas efficiency.
