## What is Drilling Engineering?

"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.

### 3/5 — Looks good, but error in Drill String calculations gives “Infinity” answer from a real world example

*2020-08-11*

Happy to help with a fix if you need

### 4/5 — Good app; requires a bit more work to be great

*2019-11-01*

Overall is a good app, but requires a bit more work to be great. The mud density increase with Barite or with Calcarb gives answers only in numbers of sacks, and not in pounds. Different parts of the world use different sizes of sacks. The app doesn’t mention what size sacks it uses.

### 2/5 — Potential

*2018-04-13*

Most of functions not working yet. Hope you get it going soon.

### 2/5 — Has bugs

*2018-03-25*

Determine oil water ratio does not work. Most other functions seem to work. This app has potential. Just not ready for prime time yet.

### 2/5 — Update?

*2017-10-27*

Please put out an update

### 4/5 — ios11

*2017-09-27*
