From Site Preparation to Production: The Full Life Cycle of an Oilfield Project Explained

Most people only see the finished well, the pumpjack, or the flare stack on the horizon. But an oilfield project goes through a long, organized chain of steps before any production ever begins. If you’re new to the oil and gas world—or if you work in a connected field but haven’t followed the full process—this guide walks you through each stage in a simple, direct way.

Oilfield work can get technical fast, but you don’t need an engineering degree to understand the basics. By the end, you’ll have a clear picture of how a project moves from raw land to a producing well.

1. Site Preparation: Building the Foundation

Every oilfield project starts at the surface. Before a rig ever shows up, crews prepare the land so it can safely support heavy equipment, handle large truck traffic, and manage environmental risks.

This phase often includes:

• Surveying the location
• Grading and leveling the land
• Building access roads
• Installing culverts or drainage features
• Constructing the drilling pad

A stable pad matters more than most people realize. If the ground settles or shifts, it can slow down the entire drilling program. Soil testing and compaction help prevent those headaches.

Some operators work with companies that handle both construction and early drilling support. If you want an example of what those services look like in practice, you can see how surface drilling and site construction fit together through providers like Charger Services.

This stage also includes environmental planning. Crews may install lined pits, erosion control, and containment structures to reduce the risk of spills or runoff.

2. Surface Drilling: Setting the Ground Rules for the Well

Once the site is ready, the next step is surface drilling. This is the process of drilling the first section of the well and installing the surface casing—a steel pipe that stabilizes the upper part of the well and protects groundwater.

You can think of surface drilling as the base of a house. If this part isn’t done right, the rest of the well will have problems down the line. It helps:

• Prevent the hole from collapsing
• Seal off shallow water zones
• Provide a stable anchor for the deeper drilling

This phase doesn’t take long, but it’s critical. The crew drills down a set depth, runs casing, cements it, and makes sure the well is isolated from the surrounding soil and water.

3. Intermediate and Production Drilling: Reaching the Target Rock

After the surface hole is complete, a larger drilling rig moves in to finish the deeper sections.

At this stage, the goal is to reach the reservoir—shale, sandstone, carbonate, or whatever formation the operator is targeting. Drilling can take days or weeks depending on the depth, geology, and weather.

Some notes worth knowing:

• Horizontal wells are now standard in most U.S. shale plays.
• Directional drilling tools help steer the wellbore with surprising accuracy.
• Mud systems cool the drill bit and stabilize the hole.
• Logging tools measure rock properties so the operator knows exactly where they are.

Drilling is expensive. According to the U.S. Energy Information Administration (EIA), drilling and completion make up more than half of the total cost of most shale wells:

This is why efficiency and planning matter so much. A slow or troubled drilling program can blow up the project budget.

4. Completion: Preparing the Well to Flow

When drilling reaches total depth, the project enters the completion phase. This step turns a drilled hole into a functioning well.

Completion generally includes:

• Running production casing
• Cementing the casing
• Creating perforations in the target zone
• Performing a hydraulic fracturing stimulation (in shale basins)
• Flowback and testing

People often think “drilling” is the main part of getting a well online. In reality, completion usually takes just as much planning and coordination.

Hydraulic fracturing gets a lot of attention, and while it’s not the focus of this article, it’s worth noting that fracs require huge volumes of water and specialized crews. That means ponds, lined containment areas, and transfer pipelines all need to be ready ahead of time.

5. Facilities and Infrastructure: Making the Site Operable

Once the well is completed, crews build the small surface facility that handles the produced oil, gas, and water.

This stage may include:

• Installing separators
• Setting storage tanks
• Laying short pipelines
• Adding power units and meters
• Building safety fencing
• Constructing containment around equipment

On some sites, teams also build water recycling systems or connect to existing midstream networks. Every site is a little different, and the design depends on production forecasts and local regulations.

Trade-off to note:
Facilities need enough capacity for peak production, but overbuilding wastes money. Engineers usually estimate early flow rates and size equipment accordingly.

6. Production: The Longest Phase

After everything is tested and connected, the well finally begins producing.

Daily operations shift from drilling crews to production teams who handle:

• Monitoring flow
• Maintaining equipment
• Adjusting choke settings
• Managing produced water
• Ensuring compliance and documentation
• Scheduling routine inspections

Some wells produce steadily for years. Others decline faster and need artificial lift systems like pumpjacks or ESPs to keep production going.

While production seems simple compared to drilling, it brings its own challenges—equipment wear, sand issues, and the need to balance well performance with long-term reservoir health.

Final Thoughts

Oilfield projects involve far more than most people ever see. From the first grader blade on raw land to the steady flow of oil and gas months later, each step depends on the one before it. When the work is coordinated well, the project moves smoothly. When it isn’t, the delays can add up fast.

If you’re involved in planning, engineering, or field operations, understanding the full life cycle helps you see how your piece fits into the larger picture. And if you’re new to the industry, it’s a good way to get familiar with how a modern well really comes together.
