    The subject of this presentation is to show and tell what is like to be out in the field.

    The overall goal of the presentation is to involve or bring the attention of the youth into

    the oil industry.


    First of all, thank you Lewis Energy for giving me this opportunity to do my internship

    with you. This presentation describes some of the things I did and learned out in the

    field using the knowledge I learned in the Oil and Gas program.

    Steps to Follow in a Facility

    1. Safety

    Personal Protective Equipment (PPE)

    Equipment maintenance or repairs

    Proper Communication

    2. While arriving to a Facility the first thing to do is check the wellhead.

    Inspect the gauges

    All the valves should have a plug in it (OSHA Regulation)

    There must be a Set Up in the Surface, Intermediate, Casing and tubing parts.

    Check for leaks in the pipes

    3. Check to the Heater

    The heater should be ON (Specially in cold weather)

    The Heater should to be around 120 Fahrenheit

    Check the Heaters gauges to see if the Big and Small Joe are functional.

    The big Joe pressure is around 75-90 Psi

    The Small Joe pressure is around 15-22 Psi

    Use Special tape to prevent the freeze in the Joes

    4. Check the Safety Equipment

    Depending on the pressure of the well, adjust the arrows in the E-stick

    The safety equipment can shut down the wellhead in case of emergency.

    5. Examine the High and Low Pressure Separators

    Revise the dump valve

    Control boxes (adjust the spring)

    Back Pressure Regulator (pressure inside the regulator)

    Glass tube (The levels of water and oil)

    Any closed valves

    The weather cap

    6. The rocket bottle is an important equipment

    It is the one that supplies pressure to the entire facility

    7. Chemical tanks

    Check the pumping time of the chemical added

    Adjust the timer on the chemical pump

    8. Clean the facility


    9. Stock tanks

    Use the Color Cut (If the tank is oil and water)

    Wait 5-8 sec then pull out the steel tape so the chemical can

    change color

    If it is just water or oil, just measure with the steel tape

    The tanks levels should stay low at all times

    Clean the measuring tape afterwards

    10. Reading of the Rock

    Take readings such as:

    Wellhead Pressure

    Static Pressure

    Differential pressure


    Spot (Predict the amount of MCF the

    Wellhead is going to make that day)

    11. Data

    All the collected data should be uploaded into a special program

    Personal Protective Equipment (PPE) include:

    Hard Hat

    Steel-toed boots

    Safety glasses

    Flame-Resistant (FR) Clothing

    H2S Personal Monitor




    Poor communication is a contributing factor in many accidents.

    Workers are often injured because safe work practices have not been effectively communicated.

    Hazard Communication Standard (HCS) published by OSHA.

    Also known as the Right to Know Law: This law gives the workers the right to know certain things

    about the chemicals they work with or are exposed to.

    The most effective way of reducing industry injuries and incidents is to understand the risks involve

    with all the hazards and work activities.

    Hydrogen Sulfide (H2S)

    Highly toxic, colorless gas that is formed by the decay of organic materials.

    It is one of the leading causes of sudden dead in the oil industry.

    It can be fatal at levels 750-1000 ppm.

    Specific training is required to work or enter an H2S environment.

    The fatality rate among oil and gas workers is now nearly

    eight times higher than the all-industry rate of 3.2 deaths

    for every 100,000 workers.

    Equipment and function The Wellhead

    Wing Valve- is the first mechanism used to close manually the well.

    Actuator- A safety system to shut-down the well automatically.

    Choke- An equipment used to decrease the pressure coming from the

    Well. (The pressure passing through the choke should be

    The same, ALWAYS)

    The Isolation Valve- The last part of the well before the pressure

    (Oil/gas) goes to the facility

    Soap launcher- An old method of Helping the well to increase the

    Pressure or dissolve water inside the well

    Plunger- The modern method of Helping the well to increase the

    Pressure. (Release a rod into the well to accumulate pressure

    Thus when it has enough pressure it can lift the rod and

    Pressure up the well.

    All the parts of the Christmas tree should have a "set up"

    For example the surface set up, intermediate set up,

    Casing set up, tubing set


    A proper Set UP has

    Seven parts:

    Bushing, Nipple, 'T" pipe,

    (2) Needle Valve, plugs

    and Gauge.

    Equipment and Function Heater

    Heater- it heats the fluids that comes from the well.

    The reason why some wells need a heater and others dont

    depends in some factors for example: the fluids are already

    Warm/hot or the difference in pressure does not exceed

    300 psi.

    Some parts of the heater are:

    Big Joe- The pressure should always be between 75-90 psi

    lower the pressure that comes from the well.

    Small Joe-The pressure should always be around 15-22 psi

    Lower the pressure even more from the well to the Big Joe to the Small Joe (From here

    there are two gas pipes 1) for the Pilot 2) to keep the heaters flame ON).

    Gauges- to read the temp of the Heater

    Heaters Regulator- To maintain a certain temperature (If the temp exceeds the

    adjusted temp, it will shut down the gas line).

    One way to prevent equipment from freezing is to wrap up the equipment with

    special tape.

    Safety Equipment

    The safety equipment in the facility can shut down the well head automatically:

    1. E-stick" boxes (2)

    Adjusted a max and min pressure in the box, thus if the pressure reaches the needles, it

    automatically shuts down the


    There are two boxes:

    2. Actuator:

    When the "wheel" is outside

    (First picture) and it has

    pressure the actuator will let

    pass the pressure to the next

    phase (Heater/High-low


    When the "wheel" is outside

    (First picture) and it does not

    have pressure the actuator will shut down the wellhead.

    When the "wheel" is inside (Second picture) the actuator is in by-pass, thus you can make any

    arrangements you need to make.

    "The purpose of the wheel is to adjust a plate inside the actuator so you can put it on by-pass or shut

    down the wellhead."

    3. Versa Valve

    Controls the pressure that helps the actuator to stay open; you can manually or remotely close it from

    the Office.

    4. Pineapple

    A third (floater/check) in the low pressure separator. The pineapple does not let the

    (water/condensate) to get to a certain level inside the separator (It is like your back up) if the

    water reaches the pineapple level it immediately shuts down the well thus the

    (water/condensate) do not reaches the flare tower.

    Right next to the High Pressure separator
