Do anybody experience in oil and gas production wells with artificial gas lift that operate without any choke valve installation at upstream the well flowlines?
I have seen many oil and gas natural flow wells that all of them have choke valve after x-tree to control the flow and/or pressure of well fluids.
But last week for the first time I visited one oil field with artificial gas lift that had not any choke valve. The information about the gas lift process are as follow: the source of producing high-pressure gas is high pressure compressor (40 mmscfd @140 barg outlet pressure) for 10 wells (each well 4 mmscfd). Each well produce 4,000 barrel oil and 3,000 barrel water per day and the first stage separator pressure is 10 barg and feed of the compressors supply from separated gas at separators. (my concern is not about gas lift line choke valve because in the gas lift line choke valve has been installed before the x-tree)
My question is that all of artificial gas lift wells dosen’t need choke valve?
appreciate your guidance and experience sharing.
