When the natural energy of an oil field is not enough to fluid lift, we need a secondary recovery procedure on the well (normally, this is called artificial lift) [I]. For this case, we can use different techniques such as artificial lift by gas (ALG) [I ] . The idea of the ALG is to inject gas, and in this way to lighten the fluid. The design of this system must be made very carefully. One of ...

arguably, the natural gas transmission pipeline infrastructure in iran represents one of the largest andmost complex mechanical systems in the world. the optimization of large gas trunk lines known asigat results in reduced fuel consumption or higher capability and improves pipeline operation. in thecurrent study, a single-objective optimization was conducted for khormoj compressor station on t...

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 ...

In Japan, several projects to increase train speed are underway, requiring a new generation pantograph that achieves further reduction in aerodynamic noise. However, as reduction of pantograph noise usually conflicts with the stabilization of its lift force characteristics, a number of experiments have to be conducted to develop a new type of pantograph. The aeroacoustic and lift force characte...

The majority artificial lift used in MPA Field use PCTGL (Permanent coil tubing gas lift). is installed on several monobore well or dual well. Some wells the have waxy HPPO oil character with pour point between 85-100oF API 30-35. "MM-1" has a 95oF. high Pour of will be problem to solved. MM-1 produced PCTGL. From simulation, design was obtained at depth 2250 ft. With oil, depressant injection ...

Conceptual wing design analysis methods are combined with numerical optimization to find minimum drag wings subject to constraints on lift, weight, pitching moment, and stall speed. Minimum drag tip extensions and winglets are compared using nonlinear optimization. The minimum drag trapezoidal tip device depends on the ratio of the maneuver lift coefficient to the cruise lift coefficient, altho...
