Hole Volumes vs Drilling Engineering
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Hole Volumes
This app calculates various oilfield volumes, including hole, annular, tubing, and displacement. Users input depth, casing, and tubing sizes to get quick results. It supports both metric and standard units and allows for custom pipe sizes.
- Calculate hole volumes
- Calculate annular volumes
- Calculate tubing volumes
- Calculate displacement volumes
- Supports metric and standard units
- Custom pipe size entry

Oilfield Tubing Volumes allows you to easily calculate hole, annular, tubing, and displacement volumes. Just enter the depth, casing, and tubing size and the app will do the rest! -Made specifically for oilfield/service rig applications. -Easily figure out hole volumes by putting in the hole depth and selecting the pipe and casing size. -Change from metric to standard depths and sizes -Enter custom pipe sizes *These numbers will be very close, but due to pipe weights and make, volumes may be slightly off.
Drilling Engineering
This app provides essential tools for oil and gas professionals involved in drilling operations. It offers unit conversions, a comprehensive drilling calculator, API tubular data, stuck pipe problem identification, and well control calculations.
- Petroleum Unit Conversion
- Drilling Calculator (90+ calculations)
- API Tubular Data
- Stuck Pipe Problem Identification
- Well Control Kill Sheet

"Drilling Engineering" mobile application is provided by Drilling UTC of Pertamina for anyone who works and or engaged in oil and gas activity, particularly in planning and drilling operations. "Drilling Engineering" mobile application include: 1. Petroleum Unit Conversion to convert the units are often used in drilling operations, including the Temperature, Pressure , Density , depth , and other parameters. 2. Drilling Calculator consists of approximately 90 base drilling calculations, both in drilling operations and design. 3. API Tubular Data provides tubular data base such as casing, tubing, and drill pipe, give a quick access to pipe dimension and strength. 4. Stuck Pipe Problem Identification is based on Texas Drilling Associates Stuck pipe logics. Analyze the cause of stuck pipe, could be occurred because of Pack-off/bridge, Wellbore Geometry and Differential Sticking. 5. Well Control Kill Sheet is an IADC based calculation to stop the flow of an influx from formation using wait and weight method.

Verdict
The clearest difference is review sentiment: Drilling Engineering at 50% against Hole Volumes's 0%. Drilling Engineering also leads on ratings volume (19 vs 3) and device support (3 vs 1). Hole Volumes's advantage is update cadence (every 5 months vs every 42 months) and rating (4.0 vs 3.8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Hole Volumes holds the better App Store score, 4.0 against 3.8. That said, the two scores are not equally well evidenced: Drilling Engineering has 19 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 0% of Hole Volumes's written reviews are positive against 50% of Drilling Engineering's, so the app with the better star average is not the one people write more warmly about.
Hole Volumes ships an update every 5 months, Drilling Engineering every 42 months. The most recent releases landed on October 2, 2026 and October 11, 2026 respectively.
