The Drilling Hydraulics provides the driller, tool pushers, engineers, chemists, students and other professionals in the petroleum industry a productivity tool helpful in drilling of oil wells for hydraulics calculations, optimization of the penetration rate and can help on the decision on selection of bit nozzles.

Resources available:

1. Defining the parameters of the well, drill string, drill bit, mud (fluid), mud pumps, circulation lines on surface, diameter and coefficient of choke and more;
2. Options outstanding: Injecting into the drill string with the return flowline or by injecting the kill line to return the choke;
3. Options wells in floating units or in drilling land rigs;
4. Use of two mud pumps in parallel;
5. Choice of rheological models (Bingham and Power);
6. Calculations of the hydraulic drill bit and the system by friction;
7. Frictional losses in all sections, also showing the length, hydrostatic and Reynolds number in each section;
8. Calculation of the ECD on bottom hole and the casing shoe;
9. Hydrostatic calculations at the bottom hole and the casing shoe;
10. Calculation of bottoms up time;
11. Pressure x Flow chart with touchscreen and rotation (portrait / landscape) and scale definition;
12. Selecting the system of units;
13. Saves the data to reload later;
