"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.
