The Sunny drilling design and analysis system (SunnyDrilling for short) is a must-have analysis tools for drillstring mechanics and hydraulics in directional and horizontal well drilling design and engineering. SunnyDriling provides accurate and reliable analysis results, which helps users optimize the design, effectively avoid downhole troubles and reduce drilling costs and drilling difficulties. It can also help continuously improve and optimize the subsequent drilling design and operations by carrying out post-drilling analysis.

SunnyDrilling contains the following four modules:

•SunnyBHA – Establish and manage the drilling string and BHA
•SunnyWG – Manage the well structure/casing programme
•SunnyT&D – The drill string T&D analysis using three-dimensional finite element
•SunnyHydraulics – Conventional hydraulic calculation and analysis

See the introduction of sub-modules for detail.
