“Gas lift technology for crude oil extraction” is my project which i have done from Oil and natural gas corporation Ahmedabad asset,india.where i have noted how the gas lift technology will apply to the well and how will be the production with it.the depth of the well and the fluid level inside the well are the most important factor to select the “position of valves to lift fluid “to out and the “pressure of the injection gas”.also the types if gas lift like continues and intermittent and its application also advantages and disadvantages . The new technology “DUAL WELL GAS LIFT “Also researched and added to my project and its application.here we using a single well for producing oil from multiples zones of reservoir .it wil decrease drilling Cost.but it has some disadvantages also when ang problem occurs on the tubing .this is the brief about my project
