Spacing orders on the map
See how hearing orders create, change and end spacing units, and which surveyed wells sit inside them.
Well paths by operator
See where wells in the same operator group cluster around Williston. Open the map for the color legend.
Overlapping spacing units
Follow the white outline of a 2,560-acre unit through its neighbors. The depth shown is approximate.

How much infill still fits?
Every Bakken spacing unit, measured against the well density its own neighbourhood has already reached, with the laterals that still fit drawn into the gaps. A geometric count from public records, by county, township and operator, beside what the NDIC orders allow. No economics yet, and it says so.

Four guided perspectives
Extraordinary paths.
A closer look.
Start with a place and a question. These short, interactive tours bring the Bakken’s wellbore geometry into focus—from a heading reversal to a stacked development pilot.
Actual mapped paths · Cameras ready to explore
Owan
Follow a lateral that turns back.
Trace the heading reversal, then use inclination colors to see the smaller changes along the turn.
Explore Owan
Nystuen
Put extended reach in perspective.
Compare depth with horizontal reach, then move closer to the lateral’s vertical profile.

Torpedo
Connect the shoreline to the subsurface.
Follow ten mapped wells outward from a compact surface area beside Lake Sakakawea.
Explore Torpedo
Hawkinson
Explore four targets in one pilot.
Compare the surveyed paths with the published staggered design across Middle Bakken and Three Forks benches.
Explore HawkinsonSource notes and display assumptions travel with each tour. Historical design targets do not verify current completed intervals.

A well is more than a point on a surface map. Move around its full trajectory, follow changes along the path, and see how it fits into the surrounding field.

Public data.
Visible assumptions.
A useful view should make its inputs and limits understandable. The methodology explains how geometry, production, and spatial measures become the layers you see.
Read the methodologyGeometry
Section classifications and engineering color views are derived from mapped paths. They are a way to explore the data, with resolution and source limitations.
Production
Historical reported production adds a time dimension. A production display does not establish a completed interval or a well’s current status.
Development
Footage capacity densities are illustrative, not calibrated forecasts. A footage balance is not a count of drillable locations, reserves, or a drilling schedule.
About me
The Bakken is home.
I’m Caleb Albertson. I was born and raised in western North Dakota and studied at the University of North Dakota. I’m a petroleum engineering professional with ten years in the Bakken oil and gas industry.
I’ve worked on frac jobs, drilling projects, and the regulatory side of the business. I’ve also worked on pipelines and the connections that bring new wells into production.
From the road, you can see a pumpjack. I built Bakken Subsurface Analytics so you can see where the well goes underground and how a spacing order on paper takes shape on the map.
