.... Electrical submersible pumps (ESPs) and gas lift are commonly used separately in lifting crude oil from wells. However, the use of downhole equipment and instruments such as ESPs that cause mixing can result in the formation of an emulsion with a high viscosity. The pressure required to lift emulsions...

... Abstract Long known for its tolerance of solids-laden fluid and wellbore deviation, gas lift is an increasingly popular artificial lift method for horizontal unconventional wells. A variation of gas lift known as Single Point High Pressure Gas Lift (SPHPGL), noted for the absence of gas lift...

... Abstract Gas lift is one of the most widely used artificial lift methods, and the use of nodal analysis to generate the gas lift performance curve is well established. However, the optimal gas injection rate is often selected as the point with maximum liquid production, which neglects the cost...

Abstract The tester set initial opening pressure of a gas-lift valve (GLV) and port size are no indication of its injection-gas passage at a given injection-gas pressure for unloading and/or gas lifting a well. The initial test rack opening pressure (P tro ) of a GLV creates an opening force...

... again. MODELING THE PERFORMANCE OF THE PLUNGER-ASSISTED INTERMITTENT GAS LIFT SYSTEM A simple model for predicting a plunger-assisted intermittent gas lift system performance under steady-state assumptions was developed using the well completion schematics shown in Figures 3 , 4 , 5 and 6...

... Abstract When performing multiple fracture treatments in horizontal Barnett Shale wells, many operators choose to utilize artificial lift to remove fracture fluids rather than incur the expense of energized fluids that may not be effective. Gas lift has been a popular artificial lift method...

... pressure and/or gas flow rate is sufficiently reduced, then other means of artificial lift (usually such as plunger lift, gas lift, or sucker rod lift) must be added to maintain production. Acoustic fluid level testing can be used to investigate the producing condition of a gas wells. Developments...

... The ESP system is initially installed in 3 wells in Wendong oilfield and the high GOR results in lower pump efficiency. The gas lift assisting system is used. The same good results are obtained. The average daily fluid production rate of each well is increased by 20t/d. Conclusions...

... was plugging its tubing near the gas lift mandrel, resulting in wireline tools being lost in hole. Attempts to gas-lift three shut-in wells in this reservoir have been unsuccessful. Measured fluid levels in these wells were way off from the supposed hydrostatic balance, indicating that obstructions, most...

... Abstract An integrated solution was required to optimise the use of gas in a complex network installed for gas lifting operations, gas export and reservoir re-injection. The solution was required because the compression facilities represent a major element of the cost of operating the field...

... Abstract Chamber-lift is a form of intermittent gas lift (GL). The chamber installation design determines the success of this type of GL operation. There are three primary reasons for selecting chamber-lift to GL a well: to lower the depth of gas injection in a low flowing BHP well...

... Abstract Experiments on intermittent gas lift were conducted in a field scale test loop to measure: a) the effect of injection pressure, liquid column length, formation gas-liquid ratio, crude API and gas flow rate injected per cycle on the liquid fallback and b) the dynamic behavior of gas...
