Challenge
Failure of gas lift valves as a result of scale deposition has been an issue that has plagued the industry for decades. In certain fields GLV´s have to be changed several times per year. Interruption of, or non-optimum gas lift assisted production will have a negative impact on field economics.
Solution
Petroleum Technology Company’s (PTC) DuraLiftTM has a unique geometry to ensure that fluid, which could cause scale deposition does not enter the check-valve area, both during gas-lift operation or when well is shut in.
