GREENHAT
You have never worked the oilfield. By the end of this tier you will understand what the industry actually is, what the money and the life really look like, how to get hired with no experience, what you need before day one, and how to not get hurt or run off once you are out there. No fluff, no recruiter sales pitch. The straight version from someone who works it.
Orientation, not certification. Where a real ticket matters — well control, rigging, gas — these lessons point you to the certified training instead of pretending to replace it. One unlock covers the full course here and in the Oil Platform app.
How it actually goes on location, not how the manual says.
Get this wrong and someone goes home hurt or not at all.
This varies by company, basin, or year. Confirm against your own situation.
The thing to remember if you forget everything else.
What The Oilfield Actually Is
Before you can get hired and not look lost, you need the map. Most guys walk onto a location with zero idea who owns what, who works for who, or what stage the well is even in. They spend their first month confused. This lesson fixes that in 12 minutes. Read it twice.
Upstream, Midstream, Downstream
The whole oil and gas business splits into 3 pieces. You need to know which one you are walking into.
- Upstream is finding and producing it. Drilling wells, fracking them, getting oil and gas out of the ground. This is the oilfield most people mean when they say oilfield. This is almost certainly where you are headed.
- Midstream is moving and storing it. Pipelines, gathering systems, trucking, tank batteries, gas plants. Some field jobs live here too, especially trucking and pipeline.
- Downstream is refining and selling it. Refineries, chemical plants, the gas station. Different world, more plant and turnaround work than wellsite work.
Almost every greenhat starts upstream, working for a service company at the wellsite. Trucking can put you midstream. Refinery and turnaround work is downstream and is its own track. When people say they work in the oilfield, 9 times out of 10 they mean upstream wellsite work.
The Life Of A Well
A well is not one job. It is a sequence of stages, and different crews and companies show up at each stage. If you understand the sequence, you understand who is on location and why.
- Lease and permit. The operator secures the right to drill and gets it permitted. No field crews yet, this is land and office work.
- Drilling. A drilling rig and its crew drill the hole, sometimes 2 miles down and then 2 miles sideways. This is rig work. Floorhands, derrickhands, drillers, the company man.
- Completion. After the hole is drilled and cased, the well gets completed so it can actually produce. This is where wireline, frac, coil tubing, and cementing crews show up. This is usually the busiest, most crowded stage on location.
- Production. The well is making oil and gas. Now it is pumpers, lease operators, and roustabouts keeping it running, plus the tank batteries and equipment that handle what comes out.
- Workover and intervention. Wells get sick. Something downhole fails, production drops, a problem needs fixing. Workover rigs, pulling units, wireline, and coil go back in to fix it. This happens over and over across a well's life.
- Plug and abandonment. At the end of its life the well gets plugged and the site reclaimed. Specialized crews handle this.
When you roll up to a location and see a tall rig drilling, that is the drilling stage and those are rig hands. When you see a smaller rig pulling rods and tubing out of an existing well, that is a workover or pulling unit. When you see a spread of red iron, sand cans, and a line of pump trucks, that is a frac. Knowing what you are looking at the first time means you are already ahead of the last 3 new guys.
Operator vs Service Company
This is the single most important distinction in the whole industry and most new guys never get it explained. Get it now.
- The operator owns the well. They are the oil company. Names like Chord, ConocoPhillips, Continental, Devon, EOG, Hess. They decide what happens and they pay for everything.
- The service company does the actual work for the operator. They own the rigs, the wireline trucks, the frac spreads, the pulling units. Names like Halliburton and SLB, plus hundreds of smaller independents you have never heard of.
- The company man, sometimes called the consultant or the rep, is the operator's man on location. He is the boss of the wellsite. He does not work for your company. He tells your company what he wants done, and your crew does it.
You will almost certainly start by working for a service company, not an operator. The operator hires the experienced and the office. The service companies and independents are the ones who hire green hands off the street and put a shovel or a tool in their hand. That is your door in.
The Service Lines, And Where You Could Land
Service company is a huge umbrella. Here are the main field service lines and roughly what they do, so you know what you are applying into. Tier 3 of this course goes deep on the big ones.
- Drilling contractors. They run the drilling rigs. Entry job is floorhand, also called worm or roughneck. Hard physical rig floor work.
- Frac and pumping. They pump fluid and sand downhole at high pressure to break the rock. Big crews, lots of equipment, lots of greenhat entry through equipment operator and ground positions.
- Well servicing and workover. Smaller rigs and pulling units that fix and maintain producing wells. Huge in the Bakken and the Permian. Common greenhat entry as a floorhand on a pulling unit.
- Cementing. They pump cement to set casing in place. Specialized pumping work.
- Snubbing, also called hydraulic workover. They run pipe into or pull it out of a well that is still under pressure, using a hydraulic jack instead of a conventional rig. Specialized, higher-skill pressure work.
- Coil tubing. They run a continuous steel pipe off a giant reel into the well for cleanouts and intervention. Closely related to wireline, overlapping skill set.
- Wireline. They run tools down the well on an electric or slickline to perforate, log, set plugs, and gather data. Entry job is the ground hand, sometimes called the operator helper. Heavy on rigging up, lifting, and learning the tool string.
- Flowback and well testing. After a well is fracked and brought on, they control, separate, and measure what comes back, oil, gas, water, and sand, before it settles into steady production. Common helper-level entry on completion crews.
- Production and lease operations. Pumpers and lease operators who keep producing wells running. More steady, less crew chaos, often a different pace.
- Roustabout and construction. There are really 2 flavors. One is a dedicated roustabout or construction outfit, crews that build, maintain, and clean up locations across a lot of wells, dirt work, setting equipment, pipe, and lease upkeep. The other is a roustabout attached to a rig or a single operation, doing whatever general labor that location needs, which is more at the beck and call of whoever is running the job. Both hire green and both are among the most common true entry doors.
- Support services. Trucking, hot oil, water transfer, vacuum and hydro excavation, and rentals. Massive workforce, tons of entry points, and trucking rewards a CDL.
Company names and which service lines are busiest shift by basin and by year. The list above is the structure, which is stable. Which specific companies are hiring near you right now is something to check locally when you are ready to apply. Lesson 4 covers how.
Where The Work Is: The Basins
Oil and gas comes from specific regions called basins or plays. The work is where the rock is. The major US onshore basins:
- Permian Basin, West Texas and southeast New Mexico. The biggest by far. Most rigs, most jobs, most of the national oilfield workforce. If you want the highest odds of getting hired, this is the deepest pool.
- Bakken, western North Dakota and eastern Montana. Smaller than the Permian but a major play. Brutal winters, strong pay, tight-knit. Dickinson, Williston, Watford City are hubs.
- Eagle Ford, South Texas. Major play, lots of completion and production work.
- Other significant areas include the Marcellus and Utica gas plays in Appalachia, the Anadarko in Oklahoma, the DJ Basin in Colorado, and the Gulf of Mexico offshore.
You go where the work is. Guys relocate to a basin, live in a camp or a cheap rental, and work. If you are not already near a basin, getting hired probably means being willing to move to one or drive a long way. Nobody is going to bring the oilfield to your hometown.
Is Now Even A Good Time?
You will see headlines screaming both directions. The truth in 2026 sits in the middle, and you should hear it straight.
The big oil companies have been cutting jobs, mostly corporate, engineering, and consolidation cuts after mergers. That makes scary headlines. At the same time, actual field activity ticked up in early 2026, and service companies and independents, the exact outfits that hire green hands, keep hiring because field turnover is constant and a wave of experienced hands is retiring.
Ignore both the industry is dying headlines and the infinite jobs hype. The entry door is open because the field always churns through people and the experienced crowd is aging out. But this business is cyclical, it always has been. Your job security never comes from the industry being hot. It comes from being good, being reliable, and being willing to move to where the work is.
You roll onto a location for your first day with a service company. There is a guy in a clean truck and clean FRC who does not seem to be doing any of the physical work, but everyone checks with him before they do anything. Your crew lead tells you to go grab something and the guy in the clean truck tells him no, do it this other way first.
Who is that guy, and does he work for your company?
Show the debrief
That is almost certainly the company man, the operator's representative. He runs the wellsite and tells your company what he wants done. He does not work for your service company, he works for the operator who owns the well. Your crew lead answering to him is exactly the operator and service company relationship in action. You take direction through your own chain of command, but understand the company man is steering the whole location.
A buddy tells you he got on with an oil company and is making great money. You apply to that same oil company online for an entry-level field job and never hear back, even though you are willing to do anything.
Why are you not hearing back, and where should you actually be applying?
Show the debrief
The operator, the oil company, mostly hires experienced people and office or technical roles. They rarely take green hands straight off the street into the field. Your door in is the service companies and independents, the ones who own the rigs, trucks, and equipment and need bodies they can train. Your buddy may say he works for the oil company, but odds are he actually works for a service company on that operator's location. Redirect your applications to service companies and staffing outfits, not the operator.
