Petrix Maps Oilfield Navigator

Review by eFreeware

Anyone whose working day involves wells rather than offices will recognize the problem Petrix Maps is built around: knowing where a site actually is, and getting to it without a string of phone calls or a folder of coordinates. Epitosoft's app covers wells and oilfields in 23 US states, from Texas and Oklahoma to North Dakota, Alaska and California, and turns that into a searchable, mappable, navigable layer. If your work regularly takes you to producing wells, drilling locations or leases, this is the sort of tool that replaces a stack of printed directions.

The app is free to install, has no ads, and offers in-app purchases. It has been on Google Play since May 2019 and has passed 50,000 installs, with a 4.2 average across 252 ratings. That is a modest but steady footprint for a niche business tool, and the September 2025 update suggests it is still being worked on rather than left as-is.

What appeals to me most is the narrowness of the focus. This is not a general map with an oil and gas filter bolted on; it is a wellsite directory with routing attached. For a pumper, a landman, a drilling consultant or a small operator, that distinction matters more than any list of features.

Searching by API number, lease or operator

The developer leads with search, and the options are broader than a simple name lookup. You can find locations by well name, by API number, by lease name or by operator, which covers the four ways most people in the industry actually refer to a site. If you have a permit in front of you with an API number on it, you can go straight to that well; if you only know who operates in an area, you can start there instead.

The second half of that search story is spatial. Rather than typing anything, you drag and drop a pin on the built-in map and see what is nearby. That is the workflow I would expect to use most in the field: you are already looking at a stretch of county, and you want to know which wells sit within reach of where you are standing or driving.

The developer describes the search as fast and intelligent, which is the kind of claim worth taking with the usual caution until you have tried it on your own patch of ground. What is concrete is the range of entry points and the fact that results land on a map rather than in a list of coordinates.

Map modes, layers and sharing

Around the search sit the features that make the app usable as a working map. Topographic data is available in normal, hybrid, satellite and terrain modes, so you can switch between a clean road view and imagery or elevation depending on whether you are planning a route or reading the ground around a location. Each location also carries detailed information, which is what makes a pin useful rather than just a dot.

Favorites are there for the sites you return to, which is the sensible way to handle a patch you visit weekly. Sharing is built in as well: you can send a location to someone else along with routing directions, which is how a dispatcher, a colleague or a contractor would hand off a visit without a phone call.

The most recent update added lists to the layers feature, so whole lists can be toggled on and off the map alongside custom pins. For anyone tracking several groups of wells at once, that is a meaningful change to how much clutter sits on screen at any moment. Enterprise users also gained custom routing, which the developer says avoids inaccessible roads and restricted areas, a detail that matters in oilfield country where the shortest line is often a lease road you are not permitted to use.

What the app asks of you

The app itself is free and carries no advertising, but in-app purchases are part of the picture. Premium is where unlimited searches and secure cloud storage of your data sit, according to the developer, with the cloud storage framed as protection against losing your saved work. Anyone planning to lean on the app daily should assume a paid tier is part of the long-term setup.

The app also uses a cloud-based system, which is convenient if you move between a phone and a tablet.

The database itself is updated in the cloud at no extra charge, so the well information you see is drawn from a source that keeps moving rather than a snapshot frozen at install. Coverage is the other constraint worth naming plainly: 23 states are included, listed by name, and if your work sits outside that footprint the map will not have much to say about it.

Getting the most from it in the field

The sensible way to start is to treat the app as a personal map of your own territory rather than as a national reference. Build favorites around the wells you actually visit, and use the drag-and-drop pin to sweep an area before you commit to a route. Over a few weeks that turns into a shortlist that reflects where you really go, which is more useful than any general search.

If you work with other people, the sharing feature is worth adopting early. Sending a location with directions attached is faster than describing a turnoff, and it means the person receiving it gets the same pin you are looking at rather than an approximation. Teams that already coordinate by phone will notice the difference quickly.

For anyone managing several leases or operators at once, the layer toggles are the feature to learn properly. Being able to switch a whole list off the map keeps the view readable when you are focused on one group of wells, and switching it back on when you widen your scope costs nothing. Enterprise users with restricted access to certain roads should look at custom routing before relying on default directions, since the developer built it precisely for that situation.

Finally, keep the app updated. The database and the app itself both change, and the September 2025 release brought both the list toggles and the routing addition along with general fixes and improvements.

A focused tool for people who work wells

Petrix Maps does one job and does it without decoration. It finds wells, shows them on a map you can read in several modes, and gets you to them with directions you can pass on to someone else. The 23-state coverage, the four search routes, the favorites and the layer controls all point in the same direction: fewer wasted hours locating a site.

The trade-offs are honest ones. Coverage stops at 23 states. Premium is where unlimited searches and cloud data storage live, so heavy users should expect to pay something. And the app leans on its cloud-based system, which is what makes multi-device use possible.

For a pumper, a land or lease professional, a consultant or a small operator working within those 23 states, this is a reasonable free starting point that scales into a paid one as your use grows. If your wells sit outside that map, the app simply has nothing to offer you.
