What are base maps?

A base map is a foundation for building other maps and doesn’t include any geological information.

Most information included on a base map:

Well location
Well operator
Well name/number
Well depth
Well status
Well API numbers
Abstracts
Surveys
Sections
Townships
Ranges

Most often, base maps are used by geologists who want to build their own structural maps as a foundation on which they start recording their own subsurface information and begin their contouring process.

A base map will also be useful to anyone interested in the location of drilled wells in a certain area.

“I finally have enough data to work with”

Before using your maps, I had to work with limited state data, which didn’t have enough information on the new areas I needed to explore. I especially appreciate the fact that your maps contain the old well information, which is an important part of a basin's history.

“More accurate and valuable maps than from other providers”

I used Geomap maps to create other custom maps for my projects. Before using Geomap, I was relying on state-level maps, which weren’t accurate enough. I found that your maps provide more valuable and accurate information.

I also appreciate Geomap’s friendly and helpful team, who delivered high-quality maps I ordered in a timely manner.

How Geomaps maps are created Hand-drawn by geologists with 30+ years of experience, updated quarterly

Creating a contour map is a highly interpretive process. And although a computer can create a map much faster, a map created by an experienced geologist is usually more accurate.

The reason for it is that a computer spreads contours while relying on a mathematical calculation and not a geological interpretation. But an interpreter who knows the geology of an area incorporates all the aspects of local geology into that contoured map.

For example, a computer might evenly space the contours between the two points with different elevations, where in reality a monocline may exist. An experienced geologist familiar with the area will include the axis of a monocline, which will result in a more accurate map.
