MJ has an unrivaled well log library of over 3 million wells. We have all the recent wells, and legacy well logs no other vendor has access to.
Our well log library is FREE to browse and view well log headers. No subscription or membership fees.
LAS is sold by the curve, not the well or the log. You choose, and pay for, only the curves you need.
LAS is application ready and works seamlessly in the applications you already use.
Our Raster Well Logs are application ready and work seamlessly with the applications you already use and are downloadable 24/7.
You can order as many or as few well logs or LAS curves as you require. You do not need to subscribe to the world.
We also have discounted packages and volume discounts and we are easy to deal with.
If you are using well logs you should be looking at MJ Logs.
