Definitions

  • the present invention refers to individual subsea solutions to be applied in production well for gas-liquid separation and injection well for compression or pumping of the gas or water current in subsea systems of oil exploration.
  • the present invention refers to a unit of gas-liquid separation ( 1 ) that is connected to an adapter base of production BAP or “Tubing Head” ( 2 ), or alternatively in a well head with string suspensor previously installed in the production well.
  • Said unit of gas-liquid separation ( 1 ) comprises also the barriers necessary to safety and control of the well, such that to discard the use of a wet Christmas tree (“X-tree”).
  • the unit of gas-liquid separation ( 1 ) directs the separated gas for a flow line ( 3 ) through the BAP ( 2 ) mandrel.
  • the said unit of gas-liquid separation ( 1 ) may also provide the mandrel for connecting the flow line ( 3 ) to the gas outlet. Doing so, the separated liquid is sent to a second flow line through a second mandrel in the BAP.
  • the unit of gas-liquid separation ( 1 ) may also provide the mandrel for connecting the liquid flow line.
  • the mandrel for liquid outlet of the unit of gas-liquid separation ( 1 ) may be provided in its top, easing the connection with SPA or TLD for sending the liquid current to the surface facilities.
  • the solution according to the present invention comprises a unit of compression or pumping ( 4 ) that is directly connected to a BAP or (“Tubing Head”) ( 5 ) or to a well head with string suspensor.
  • the flow line having gas or water to be injected may be connected to BAP or (“Tubing Head”) ( 5 ) or, alternatively, directly to the unit of compression/pumping ( 4 ).
  • the gas or liquid is then compressed or pumped to the injector well.
  • said unit of compression/pumping ( 4 ) also has the barriers necessary for safety and for control of the well, which also makes the use of a wet Christmas tree (“X-tree”) dispensable.
  • the solution according to the present invention is easily applicable to scenarios with several wells where the gas and liquids produced or to be injected may be distributed through the subsea arrangement having traditional equipment, such as manifolds and PLEMs.
