Design of a Thermally-Actuated Gas Lift Safety Valve
Gas-lifted oil wells are susceptible to failure through malfunction of gas lift valve assemblies (GLV). One failure mode occurs when the GLV check valve fails and product passes into the well annulus, potentially reaching the wellhead. This is a growing concern as offshore wells are drilled thousands of meters below the ocean floor in extreme temperature and pressure conditions, and repair and ...
متن کاملDesign of an Electronically - Actuated Gas Lift Safety Valve
Gas lift valves are widely used in oil production fields to pump recycled gas and nitrogen into the production tubing, to sustain production by aerating the oil and lifting it to the ground or sea surface. Today's industry standard, a pressure-actuated valve, is susceptible to various modes of failure, including corrosion and jamming. Safety mechanisms are needed to seal the valve in case of a ...
متن کاملOptimizing and Stabilizing the Gas Lift Operation by Controlling the Lift Gas Specific Gravity
One of the factors which affects the gas lift performance is specific gravity of a lift gas (or the Molecular weight), which can influence the gas solubility in oil and has a direct effect on the gas lift performance. There are some previous researches which have included the lift gas specific gravity in their modeling, but in none of them, a comprehensive research about the effect of lift gas ...
متن کاملMitral Ball-Valve Prosthesis
REPLACEMENT of nonfunctioning valves is a significant recent advancement in the correction of cardiac valvular disease. The most widely used artificial device replacing the mitral valve is the Starr-Edwards ballvalve prosthesis.' Its effectiveness was shown in recent reports by the marked clinical improvement in properly selected patients.2 However, cardiologists and cardiac surgeons are faced ...
