3. Artificial lift is a process used on oil wells to increase pressure within the reservoir and encourage oil to the surface. When the natural drive energy of the reservoir is not strong enough to push the oil to the surface, artificial lift is employed to recover more production. Artificial Lift: what & why
4. Why Artificial Lift? • When the production reaches the limit of 10bbl/day (commonly known as stripper wells). • The reservoir pressure gets declined.

6. SRP (Sucker Rod Pump) Beam pumping, or the sucker-rod lift method, is the oldest and most widely used type of artificial lift method. It is made up of several components, some of which operate aboveground and other parts of which operate underground, down in the well.

23. Introduction • The oldest and most widely used artificial lifting method of the oil wells is the sucker rod pumping. • Most of the stripper wells use sucker rod pumping. • It is possible to lift 1000bbl/day from the depth of about 7000ft and 200bbl/day from the depth of 14000ft by SRP. • Presence of H2S hampers the depth by increasing from 4000ft to 10000ft.
24. Types of pump • Casing pump. • Tubing pump. • Rod pump with traveling barrel. • Rod pump with stationary barrel.
