Technology of multiformation oil production allows recovering of oil simultaneously from two formations of a single well with separate flow rate measuring of each formation; increasing oil production; involving idle formations and reducing drill footage. For dual formation oil production the following pump types can be used: SRP-SRP, ESP-SRP as well as ESP-ESP, natural flow-natural flow. Sucker rod pumps can be specially designed for complicated well conditions or equipped with accessories.
Dual completion SRP-SRP is used for simultaneous dual oil production from two formations.
Dual completion ESP-SRP equipment is used for simultaneous dual oil production from two formations according to scheme: bottom – ESP, top – SRP.
Dual completion SRP-ESP equipment is used for simultaneous dual oil production from two formations according to scheme: bottom – SRP, top – ESP.
Dual completion GAS-SRP equipment is used for simultaneous dual oil and gas production from two formations according to scheme: bottom – gas, top – SRP.
Dual completion ESPCP-SRP equipment is used for simultaneous dual oil production from two formations according to scheme: bottom – ESPCP, top – SRP.
Dual completion natural flow-natural flow is used for simultaneous dual oil production from two formations according to scheme: bottom – natural flow, top – natural flow.
