       FIELD OF THE INVENTION 
       [0005]    One or more embodiments of the present invention relate to soil and groundwater remediation gas injections and more specifically relate to a method and system for delivering air, oxygen, and ozone gases through a single manifold for remediation for allowing for the injection of different gases or gas mixtures using a single distribution manifold into different injection wells in an injection well field. 
       BACKGROUND OF THE INVENTION 
       [0006]    The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon. 
         [0007]    An injection well is typically a vertical pipe in the ground into which water, other liquids, or gases are pumped or allowed to flow. 
         [0008]    One application for an injection well is waste water disposal, in which treated waste water is injected into the ground between impermeable layers of rock to avoid polluting fresh water supplies or adversely affecting the quality of underground water supplies. Injection wells are usually constructed of solid wall pipe to a sufficient depth for preventing the injected material from mixing with the surrounding environment. 
         [0009]    Another use of injection wells is for the production of petroleum. Steam, carbon dioxide, water and other substances may be injected into an oil-producing well in order to maintain reservoir pressure, heat the oil and/or lower the oils viscosity, thereby allowing the oil to flow and be recovered. 
         [0010]    In view of the foregoing, it is clear that these traditional techniques are not perfect and leave room for more optimal approaches.

That is, there are numerous modifications and variations of the invention that are too numerous to be listed but that all fit within the scope of the invention. Also, singular words should be read as plural and vice versa and masculine as feminine and vice versa, where appropriate, and alternative embodiments do not necessarily imply that the two are mutually exclusive. 
         [0026]    It is to be further understood that the present invention is not limited to the particular methodology, compounds, materials, manufacturing techniques, uses, and applications, described herein, as these may vary. It is also to be understood that the terminology used herein is used for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention. It must be noted that as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include the plural reference unless the context clearly dictates otherwise. Thus, for example, a reference to “an element” is a reference to one or more elements and includes equivalents thereof known to those skilled in the art. Similarly, for another example, a reference to “a step” or “a means” is a reference to one or more steps or means and may include sub-steps and subservient means. All conjunctions used are to be understood in the most inclusive sense possible. Thus, the word “or” should be understood as having the definition of a logical “or” rather than that of a logical “exclusive or” unless the context clearly necessitates otherwise. Structures described herein are to be understood also to refer to functional equivalents of such structures. Language that may be construed to express approximation should be so understood unless the context clearly dictates otherwise. 
         [0027]    Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art to which this invention belongs. Preferred methods, techniques, devices, and materials are described, although any methods, techniques, devices, or materials similar or equivalent to those described herein may be used in the practice or testing of the present invention.

         [0056]    The following figures illustrate the programming of a PLC using step programming to control the injection of gases into a well field and using an HMI touch screen to interface with the program. The programming of a PLC using step programming, a drum timer subroutine or a custom developed subroutine that simulates a drum timer to control the injection of gases into a well field and using a computing device to interface directly with the PLC program for making modifications to the gas injection process. Furthermore, the figures illustrate using a commercial or custom made electro-mechanical drum sequence/timer and hard programming the drum sequence/timer to control the injection of gases into a well field and performing modifications to the PLC programming for controlling the injection of gases into a well field via the modification of cams, pins or other similar devices, without the need for a human machine interface. 
         [0057]    Furthermore, the figures illustrate using a PLC in conjunction with a computing device to allow field operators to program and re-program when, where and what gases may be injected in an injection well field. Furthermore, the figures illustrate utilizing a drum timer subroutine or custom built program to rotate through the valves in the distribution manifold and selecting the, step, duration and gas or gas mixture to be injected into a particular injection point by changing the settings in a drum time subroutine or loading new variables into a custom built program that reproduces the functions of a drum timer. A means of reducing the number of outputs needed for gas selection may be configured by selecting one gas or gas mixture as the default gas thereby reducing the number of outputs by one. 
         [0058]    Furthermore, the figures illustrate utilizing a drum timer subroutine or custom built program to rotate through the valves in the distribution manifold and selecting the, step, duration and gas or gas mixture to be injected into a particular injection point by changing the settings in a drum time subroutine or loading new variables into a custom built program using a series of load, memory, compare, counter, if statements and timing subroutines for reproducing the functions of a drum sequence/timer. 
         [0059]    Furthermore, the HMI software/hardware illustrated in the figures may be provided using graphical means. 
         [0060]    Furthermore, a means of reducing the number of outputs associated with the drum timer subroutine or custom ladder logic for gas selection may be configured by selecting one gas or gas mixture as the default gas thereby reducing the number of outputs needed by one. 
         [0061]    Furthermore, the figures illustrate using an electro-mechanical drum timer to control when, where and what gases may be injected in an injection well field. The programming of electro-mechanical drum timers may be accomplished via the use of cams or pins depending on the manufacturer of the electro-mechanical drum timer. The duration of the injection period may be a function of the electro-mechanical drum sequencer/timer clock motor, length of the cam or the number of pins in the drum. The sequence of injection may be accomplished by either re-wiring the outputs of the electro-mechanical drum timer or the placement of the cams or pins within the time sequence. The selection of gases may be accomplished by placing a corresponding cam(s) or pin(s) on the electro -mechanical drum timer along the same line as the injection point being affected. A means of reducing the number of outputs for gas selection may be configured by setting one gas or gas mixture as the default gas thereby reducing the number of outputs needed by one. 
         [0062]    The connections between devices may be accomplished via cables utilizing a wide variety of connectors with non-limiting examples such as USB, Serial Port, RS-232, RJ-11, DB-9 and DB-25 for transferring information bi-directionally between the PLC and the HMI or between the PLC and the computing device. 
         [0063]    The connections for the Electro -Mechanical Drum timer may be accomplished via a series of cams, pins and similar devices actuating micro switches and properly rated power cables or wires.

         [0090]      FIG. 4A-E  illustrates a method for programming PLC, in accordance with an embodiment of the present invention. 
         [0091]      FIG. 4A-E  presents a flow chart  400  illustrating an exemplary process for the programming of a PLC using step programming to control the injection of gases into a well using an HMI touch screen for user interface. 
         [0092]    A PLC in conjunction with an HMI touch screen enables users to program and re-program the control of gases injected in an injection well field. 
         [0093]    In the present embodiment, the process initiates in a step  5402  ( FIG. 4A ). With the starting point being the start screen on the HMI (S 404 ). User may perform step/setup selection (S 406 ) for navigation to starting step/setup stages to program (S 408 ) the user selected step/setup stage. If not selected, (S 407 ), present current HMI screen. Once selected load parameters and values for step/setup stage selected (S 408 ) and load the selected step/setup stage to assigned v-memory location in c-more panel for display (S 410 ). Loads current user selected V-memory word(s) bit addresses to assigned second V-memory word(s) bit addresses assigned to HMI display which shows which injection points are currently programmed to be on (S 412 ) ( FIG. 4B ). If the valves selection screen bit enabled (S 413 ) load valves selection display grid (S 416 ) and write V-memory word(s) bit addresses from stored second v-memory address in PLC and write internal bit values to HMI screen for display to show which valves are currently on or off for the step/stage being programmed (S 418 ). If the valves selection screen bit is not enabled, present current screen (S 414 ). User then selects valves/injection points to be on for step/stage being programmed utilizing the HMI display which modifies the V-memory word(s) bit addresses to 1&#39;s and 0&#39;s of the users choosing (S 420 ). If the user initiates the positive differential contact and it goes true ( 1 ) (S 422 ), then the updated 1&#39;s and 0&#39;s in the V-memory word(s) bit addresses are written (S 426 ) ( FIG. 4C ) to the first v-memory location assigned to the step/stage being programmed (S 428 ) ( FIG. 4C ). If the user does not initiate the positive differential contact then present the current display information and no change is performed to the first V-memory word(s) bit addresses (S 424 ) ( FIG. 4B ). If next step or previous step enabled (S 430 ) ( FIG. 4C ) load step/stage V-memory word(s) bit addresses for step/stage selected (S 434 ). If next step or previous step is not enabled, present current display information (S 432 ). 
         [0094]    For another step/stage to perform (S 436 ), execution of flow chart  400  transitions to S 412  ( FIG. 4A ).

If another step/stage is to be processed (S 440 ) and if step run enable bit on (S 442 ) ( FIG. 4D ), user chooses to enable step/stage being programmed by pressing the enable button on the HMI screen the step/stage for execution during run time (S 446 ). If another step/stage is to be processed (S 440 ) ( FIG. 4C ) and if step run enable bit configured as not on (S 438 ) ( FIG. 4D ), the step/stage currently being programmed is configured for not being executed during run time (S 444 ). 
         [0096]    If another step/stage is not to be processed (S 440 ) ( FIG. 4C ) and if current step/stage being programmed normally closed ozone enable bit on HMI programmed open by user (S 448 ) ( FIG. 4D ) ozone generator output coil enabled for step/stage currently being programmed (S 450 ). Ozone generator configured for execution during run time, step/stage is executed and ozone injected (S 452 ). Ozone generator alarm ring enabled when step/stage being programmed is executed (S 454 ). If current step/stage being programmed normally closed, ozone enable bit on HMI not programmed open by user (S 448 ) and ozone generator output coil not enabled for step/stage currently being programmed (S 456 ).

Ozone generator alarm ring disabled when step/stage being programmed is executed (S 460 ). 
         [0097]    If the current step/stage being programmed by user run time HMI button is not pressed (S 462 ) ( FIG. 4E ), then present current screen (S 464 ). If current step/stage being programmed by user run time HMI button is pressed (S 462 ), then display numeric keypad (S 466 ) for step/stage run time when step/stage is executed during run time. If new value entered (S 468 ) write new value to assigned v-memory location and call up programmed run time for step/stage being programmed when step/stage is executed during run time (S 472 ). If no new value entered (S 468 ) on numeric keypad, then current value stored for step/stage being programmed is not changed (S 470 ). 
         [0098]    Flow chart  400  terminates execution (S 474 ). 
         [0099]      FIG. 5A-G  presents a flow chart illustrating the method of programming system using the HMI touch screen, in accordance with an embodiment of the present invention. 
         [0100]    In the present embodiment, the process initiates in a step  5502  ( FIG. 5A ). User presented start screen for viewing (S 504 ). If system control screen selected (S 506 ), load control screen for system start on ozone or oxygen/air (S 510 ). If system control screen not selected (S 506 ) present current display of information (S 508 ). If user does not select air/oxygen control relay to on utilizing the button on the HMI screen display (S 512 ), transition to execute screen for air/oxygen and present current screen (S 514 ). 
         [0101]    If user selects air/oxygen control relay to on utilizing the button on the HMI screen display (S 512 ) transition to execute screen for air/oxygen and load step/stage setup values and parameters for the programmed starting step stage selected by the user in setup mode when run time configured for off (S 516 ). If starting step/stage enable bit not on (S 518 ) transition to next optional step/stage (S 520 ). If step/stage enable bit configured for on (S 518 ) ozone generator output coil is disabled, oxygen/air normally closed and control relay open in generator output relay ring (S 522 ) ( FIG. 5B ). Ozone generator configured for off when current step/stage is executed, oxygen/air is injected for the current step/stage being executed and ozone is not injected (S 524 ). For current step/stage being executed load stored V-memory word(s) bit addresses (S 526 ) and transfer stored V-memory word(s) bit addresses to internal control relay bit map V-memory locations (S 528 ). For valve control stage, configure for operation PLC output relays assigned to associated internal control relay bit map V-memory address programmed to a “one” (on) (S 530 ). Load preset time for current step/stage stored in assigned V-memory location (S 532 ) ( FIG. 5C ), subtract accumulated step/stage counter value (S 534 ), output mathematical result to assigned V-memory location in HMI for display on the screen (S 536 ), configure one minute time tick counter on (S 538 ) and current step/stage active counter increments one count per minute (S 540 ). If step/stage counter accumulated value not equal to the present value stored in assigned v-memory location for the specific step/stage (S 542 ), then remain on current step/stage (S 544 ). If step/stage counter accumulated value equals the preset value stored in assigned v-memory location for the specific step/stage (S 542 ), then in valve control stage, configure to off PLC output relays assigned to associated internal control relay bit map V-memory address programmed to a “one” (on) (S 546 ) ( FIG. 5D ). Reset currently active step/stage counter value to “zero” ( 0 ) (S 548 ). If air/oxygen switch control relay on (S 550 ) execution of process transitions to step S 520  ( FIG. 5A ). Process repeats until air/oxygen switch control relay is exercised to the off position (S 550 ). If air/oxygen switch control relay is not on, then determine if ozone switch control relay configured for on (S 552 ). If ozone switch/control relay not configured for on (S 552 ), then determine if air/oxygen switch/control relay configured for on (S 550 ). 
         [0102]    If ozone switch/control relay configured for on (S 552 ), then user selects ozone switch control relay to on (S 554 ) utilizing the button on the HMI screen display. Present execute screen for ozone and load step/stage setup values and parameters for the programmed starting step stage selected by the user in setup mode when run time configured for off (S 556 ). If starting step/stage enable bit not on (S 558 ) ( FIG. 5E ) jump to next step/stage (S 560 ). If step/stage enable bit configured for on (S 558 ), load stored V-memory word(s) bit addresses (S 562 ), output stored V-memory word(s) bit addresses to internal control relay bit map V-memory locations (S 564 ) and input valve control stage operate on PLC output relays assigned to associated internal control relay bit map V-memory address programmed to a “one” (on) (S 566 ).

If normally closed ozone run bit not open for current step/stage (S 568 ) ( FIG. 5E ), then ozone generator output coil disabled (off) for selected step/stage (S 576 ) ( FIG. 5G ) ozone generator off, air/oxygen injected, ozone not injected (S 578 ) and ozone generator alarm ring disabled for current active step/stage (S 580 ). Execution of process transitions to step  5532  ( FIG. 5C ). Process repeats until ozone switch control relay exercised to the off position. 
         [0103]      FIG. 6  illustrates a PLC that, when appropriately configured or designed, may serve as a PLC  600  for which the present invention may be embodied. 
         [0104]    PLC  600  includes a quantity of processors  602  (also referred to as central processing units, or CPUs) that may be coupled to storage devices including a primary storage  606  (typically a random access memory, or RAM), a primary storage  604  (typically a read only memory, or ROM). CPU  602  may be of various types including micro-controllers (e.g., with embedded RAM/ROM) and microprocessors such as programmable devices (e.g., RISC or SISC based, or CPLDs and FPGAs) and devices not capable of being programmed such as gate array ASICs (Application Specific Integrated Circuits) or general purpose microprocessors. As is well known in the art, primary storage  604  acts to transfer data and instructions uni-directionally to the CPU and primary storage  606  is used typically to transfer data and instructions in a bi-directional manner. The primary storage devices discussed previously may include any suitable computer-readable media such as those described above. A mass storage device  608  may also be coupled bi-directionally to CPU  602  and provides additional data storage capacity and may include any of the computer-readable media described above. Mass storage device  608  may be used to store programs, data and the like and is typically a secondary storage medium such as a hard disk. It will be appreciated that the information retained within mass storage device  608 , may, in appropriate cases, be incorporated in standard fashion as part of primary storage  606  as virtual memory. A specific mass storage device such as a CD-ROM  614  may also pass data uni-directionally to the CPU. 
         [0105]    CPU  602  may also be coupled to an interface  610  that connects to one or more input/output devices such as such as video monitors, track balls, mice, keyboards, microphones, touch-sensitive displays, transducer card readers, magnetic or paper tape readers, tablets, styluses, voice or handwriting recognizers, or other well-known input devices such as, of course, other computers. Finally, CPU  602  optionally may be coupled to an external device such as a database or a computer or telecommunications or internet network using an external connection shown generally as a network  612 , which may be implemented as a hardwired or wireless communications link using suitable conventional technologies. With such a connection, the CPU might receive information from the network, or might output information to the network in the course of performing the method steps described in the teachings of the present invention. 
         [0106]    Those skilled in the art will readily recognize, in light of and in accordance with the teachings of the present invention, that any of the foregoing optional steps and/or system modules may be suitably replaced, reordered, removed and additional optional steps and/or system modules may be inserted depending upon the needs of the particular application, and that the systems of the foregoing embodiments may be implemented using any of a wide variety of suitable processes and system modules, and is not limited to any particular computer hardware, software, middleware, firmware, microcode and the like. For any method steps described in the present application that can be carried out on a computing machine, a typical computer system can, when appropriately configured or designed, serve as a computer system in which those aspects of the invention may be embodied. 
         [0107]    All the features disclosed in this specification, including any accompanying abstract and drawings, may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.

The invention has been described above by way of illustration, and the specific embodiments disclosed are not intended to limit the invention to the particular forms disclosed. For example, the particular implementation of the PLC and HMI may vary depending upon the particular type manifold used. The system described in the foregoing was directed to water well implementations; however, similar techniques are applicable for other types of well implementations of the present invention and are contemplated as within the scope of the present invention.
