What is an executive production reference map?
An executive production reference map is composed of many reduced base maps and color-coded production data based on the geologic formation or geologic age, and includes the following information:
- Field names
- Field discovery dates
- Structural contours
- Productive horizon information
These maps are typically used to evaluate large geographic areas to present current exploration trends and brainstorm or showcase new exploration ideas.
Geomap executive production reference maps contain both historical and up-to-date information, with new well locations and subsurface data points added on a regular basis.

How Geomaps map 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.
