A beta tester notes: "Well Logs is the only App on the market to have the capabilities to load and view oil & gas wireline well log TIFF and/or PDF images. With wireline well files up to hundreds of inches long, most Apps don’t have the memory capacity to allow such images to load without crashing. But the Well Logs App has made it a priority to specifically handle such files. " Not only do we support Well Logs we support Land Maps that are 48 inches by hundreds of inches long. We also provide accelerated multipage PDF & Tiff fax file reading using technology from our PDF and TIFF viewer applications, and support all of the image formats supported by our Can Opener technology. Well logging, also known as borehole logging is the practice of making a detailed record (a well log) of the geologic formations penetrated by a borehole. The log may be based either on visual inspection of samples brought to the surface (geological logs) or on physical measurements made by instruments lowered into the hole (geophysical logs). Well logging is done during all phases of a wells development; drilling, completing, producing and abandoning. Mostly in the oil and gas, groundwater, minerals, geothermal, and for environmental and geotechnical studies. Now supports printing, TIFF to PDF, emailing of (SOME) files. 100x faster TIFF handling supporting dozens of pages. ## Key features - View large TIFF/PDF well logs - Supports files up to 11x770 inches - Cloud server for file management - Accelerated multipage TIFF/PDF reading - Supports land maps - Printing and emailing capabilities ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/well-logs/id419051479/reviews.md ### 3/5 — Well log viewer *2013-05-07* The viewer works great. It slows down with very large tif log files but does render them. I have used it to look at logs and is very useful. It needs to connect to Google drive. ### 1/5 — Mr *2012-10-19* This app is not worth the cost. It needs more work, it has potential. Its sole purpose is to view one log at a time. There is no option to rename logs or move them into folders, even though the app is able to create folders. There is no manipulation option. A note to the developers give the ability to view multiple logs simultaneously, with the option to lock each logs depth for correlation purposes. I look forward to improvements. ## Frequently asked questions about Well Logs ### What file types does Well Logs support?
