Definitions

  • the present invention relates to renewable energy power generation and more particularly to geo-pressure clean power generation applications from the over pressurized subsurface formations.
  • Geothermal energy is an important source of renewable energy it works by circulating hot water from rocks below the earth’s surface, or by pumping cold water into deep hot rocks and returning the heated water to the surface to drive steam turbines to produce electricity.
  • Geothermal energy is geographically restricted to few locations around the world and most geothermal resources cannot be utilized in a cost-effective manner.
  • the present invention provides tools and method to generate clean energy from the kinetic flow energy of the subsurface over pressurized fluid and gases downhole the wells or at wells heads as a new source of clean energy without any emission or harmful by-products through the following applications.
  • the over pressure formation/layers are defined as any pore pressure that is greater than the hydrostatic pressure of the formation water occupying the pore space which can occur at any depth
  • Some geological mechanism is providing a seal or cap to interfere with the fluid column and preventing it from achieving normal hydrostatic equilibrium.
  • the cause of over pressure is attributed to a combination of various geological, geochemical, geothermal and mechanical changes such as
  • the present invention uses Geo-pressure clean energy innovated applications to generate considerable amount of clean energy from the kinetic flow of the widely distributed high pressurized deep water layers 10 & 200 to produce Flydrogen fuel , electricity and to desalinate underground saline water and also to generate huge clean energy from natural gas flow at gas well heads directly instead of throttling and depressurization stages before gas separation processes (without any gas burning ) through the following innovative applications:-
  • the Hydrogen Producer Source Well Application (as shown in Fig-1) is designed to use the kinetic flow energy of underground water to spin down hole generators 12 inside the well (or hydro- turbines at surface) and generating a DC electric current to feed electrolysis unit 14 at surface in order to produce hydrogen gas and valuable electrolysis by-products such as Caustic soda and Chlorine gas

  • the Cross Flow Electrical Well Application (as shown in Fig-3) is designed to produce electricity by allowing a cross flow communication between normal/over pressurized aquifer 10 and low pressurized aquifer or depleted reservoir 100 inside the well as the kinetic flow energy of underground water will spin the down hole generators 12 to get electricity directly for many purposes without producing water to surface
  • the Steam Producer Source Well application (as shown in Fig-4) is designed to use the kinetic flow energy of over pressurized underground fresh water for spinning down hole generators 12 at the lower part of the well to feed electrical heaters assembly 55 at the upper part of the well to generate a pressurized steam at the upper part of the well to run a steam turbine 18 directly at surface or to use the steam directly for warming purposes at cold areas
  • the application consists mainly of
  • Electric heaters 55 assembly unit powered by downhole generators at the upperpart of the well • Isolation tubes 44 to isolate heat between heaters assembly 55 and down hole generators 12
  • the Electric Gas Producer Well application (as shown in Fig5-) is designed to Control gas flow rate at well head 50 directly by a high anti-corrosion turbine 53 (Not Turbo-expander) instead of well head chock 50 to generate huge clean electricity from the Geo-pressure kinetic energy of the flowing gas before separation 56 to save the huge unexploited energy without any major modification at well head 50 and completion structures
  • the generated clean electricity can be used to feed the nearby electric grids if possible or powering the other gas facilities as gas liquification/ separation or producing hydrogen by electrolysis to use it externally or injecting it to gas to increase its economic value the application is very beneficial for gas with high H2S/C02 content as the density and mass flow volume greater than the pure natural gas which gives more kinetic force to spin the turbines
  • the application is designed also to generate energy at LNG regasification stations to generate energy from the regasification volume expansion force instead of depressurization / regulators/valves as the gas volume expands more than 600 times while regasification instead of depressurization / regulators/valves as the gas volume expands more than 600 times while regasification
  • the application consists mainly of
  • Discharge unit 55 with compressor to evacuating gas from turbine 53 and from the By-pass pipelines while emergency or maintenance
  • the working theory of geo-pressure energy applications is to generate clean energy from the kinetic flow energy of the subsurface over pressurized fluid and gases downhole the well or at well head as a new source of clean energy without any emission or harmful by-products through the following applications.
  • the overpressure water will flow from the overpressure aquifer 10 upward to spin down hole generator assembly 12 or surface hydro-power generator and generate DC electricity to feed the electrolysis unit 14 to separate the produced water into Hydrogen gas, chlorine gas and Caustic soda.
  • overpressure water will flow from the overpressure aquifer 10 upward to spin down hole generator assembly 12 or surface hydro-power generator and generate DC electricity to feed the electric boiler 16 to heat up produced water to produce steam to run a suitable steam turbine 18 which will condensate as a fresh water at the end and to separate salts too

The gas will spin the turbine 53 and return again to the main pipeline to separation stage 56
