Optimizing Gas Lift Design: Unveiling Ideal Wellhead Temperature Across Diverse Reservoirs at Mehsana Oil Fields
Available to PurchasePublisher: Society of Petroleum Engineers (SPE)
Paper presented at the SPE Artificial Lift Conference and Exhibition - Americas, August 20–22, 2024
Paper Number: SPE-219529-MS
... lowering the wellhead temperature without any abnormal geothermal gradient. This results in lowering the opening pressure of operating gas lift valves and disturbing the grip pressure of the compressor. In mixed drive reservoirs, the wellhead temperature may be lower or higher, depending on the water cut...
