GAS LIFT-GLA ACCELERATOR (Pat. Pending)

Its purpose is to maximize production and safety in wells, produced by the GAS LIFT system. Our solutions in the gas lift system includes design, monitoring and analysis of gas elevation to maximize the performance and profitability of our customer wells through a Software (Optima GLA), providing security with the GLA and in turn optimizes the gas injection, since it applies a pumping differential pressure thanks to the special design.

Performance and profitability

GAS LIFT OPTIMIZATION

Technical Principles

The gas accelerator (GLA-Pat. Pending) is designed under the principle of Venturi which consists of a fluid moving inside a closed duct, decreases its pressure by increasing the speed after passing through a smaller section area, thus transforming the potential energy into kinetic energy.

Potential energy: It is the mechanical energy associated with the speed generated by the injection of gas.

Kinetic energy: Is the energy associated with bodies in motion, depends on the mass and speed.

Structure

The gas accelerator (GLA-Pat. Pending) consists of sixteen (16) parts (none of them mobile). The choice of materials to be used for the manufacture of these parts will be determined by the previous study of the characteristics of the well candidate; Given the presence of a high degree of corrosive elements, abrasive elements, H2S, sand, among others, the choice of materials will be made, among which we can mention: Carbon steel (4140 and 4340) and tungsten carbon.

 

Practical principles

The motor fluid (Gas) is sent from the surface to the installation depth of the gas accelerator (GLA-Pat. Pending).

The gas passes through the nozzle where it undergoes a change of potential energy to kinetic energy, reaching supersonic speeds due to the effect (Venturi).

The effect (Venturi) causes a vacuum region that introduces the flow of fluids from the reservoir, generating a decrease in the Pwf at the level of the zone of interest.

The reservoir fluids enter through the vacuum region and then into the throat, where they mix with the motor fluid at high speeds generating a mixture.

The mixture enters the diffuser where the process of transforming kinetic energy to potential energy begins.

The mixture is exposed to the system (GLA-Pat. Pending) at considerable lifting pressures where its ascent to the surface begins.
