What are detailed structure maps?

Detailed structure maps of an area show geological expression at several levels (shallow, medium, and deep horizon) as well as cross-sections—images of well logs laid side by side showing the cross-section of the earth as it is recorded by electronic tools that are put into the drilled hole.

A set of detailed structure maps of an area include, all base map features, plus the following geological elements:

Regional dips
Isolated and localized structures
Structure contoured on multiple horizons
Contour lines depth identified
Establish historical producing fields
Faults
Folds
Unconformities
Subcrops
Salt Structure
Outcrops and more

Detailed structure maps are typically used for oil and gas exploration purposes, as they allow the geologists to quickly access the geology of a large area.

“Detailed accurate maps that save us a lot of time on research”

I’ve used Geomap structure maps to assist with the development of Class I injection well permit applications. Their data is extremely useful in understanding local subsurface geology.

Before using their maps, we relied on sparse technical papers and freely available subsurface maps, which were often outdated and suboptimal.

After licensing Geomap maps, we spend less time on needless research since the data is already available and easy to access. If not for Geomap, we wouldn’t be able to get this data at all because of how much effort it would cost us.

I would highly recommend your maps for their quality and affordability, as well as the excellent customer service.

Formats & Fees Our detailed structure maps can be accessed online or licensed in a paper format or as digital files.

Digital map files

Georeferenced tiffs, shape files, or geodatabase files of the detailed structure maps for an area can only be licensed and need to be returned at the end of the licensing period.

A license fee depends on the cost of keeping a map up-to-date, including well spotting, data gathering, interpretation, as well as the amount of historical data within a map.

The minimum licensing period is one year.

To find out the exact licensing fee for a particular area, please contact our sales team.

Online access

Online access to our detailed structure maps is included in the GeoMap Online package.

Paper maps

To license a set of detailed structure maps in a paper format, please contact our sales team. The minimum licensing period is 6 months.

Structure maps can only be licensed and must to be returned at the end of the licensing period.

“Unique information I wasn’t able to find elsewhere”

I needed a geological/log library to place exploration projects in a regional geologic perspective, but couldn’t find the necessary information anywhere. With Geomap, I was finally able to access critical well, production, and contour map information, which has been invaluable for my business. I also appreciate your great customer support.

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.
