The NORO app is a free download service for 3D CAD data of the standard product range of NORO Germany and provides engineers and project managers with direct access via mobile devices. Our product range includes pipes, mouldings and distribution systems with diameters of 80 to 600 mm made from steel (powder coated or galvanised) and chromium-nickel steel as well as associated pipe connection elements. The 3D CAD models are compliant with major world standards and are suitable for use in current CAD systems, such as CATIA®, Autodesk® Inventor®, SolidWorks®, Creo™ Parametric, NX™, AutoCAD®, Solid Edge®, etc.
Directional Well Survey
Read full descriptionHide full description
This "Directional Well Survey" application provides an easy and useful tool for students and directional engineers to edit, calculate interpolations and plot survey stations of the horizontal and directional wells using the five calculation methods (tangential, balanced tangential, minimum curvature, radius of curvature, angle averaging). This application does not normally edit well planning. But it is still possible to edit only via CSV text. The well planning can be built and edited using our apps "Directional Well Planning" or "Directional Drilling" available in our portfolio. The data files (*.ddf) including well planning and survey stations are compatible and can be shared via iCloud. The well planning and survey stations can also be imported from CSV text files, for example: "MD","INC","AZI","TVD","N/S","E/W" "1000.0","0.0","0.0","1000.0","0.0","0.0" "1100.0","3.0","10.0" "1200.0","6.0","15.0" ... The values can be "quoted" or unquoted and separated by: - Comma: 1.00,2.00,3.00 - Semicolon: 1.00;2.00;3.00 or 1,00;2,00;3,00 - Tab: 1.00 2.00 3.00 (TSV file) - Space: 1.00 2.00 3.00 Please, before purchasing, make sure that this application will be useful for you. This application was developed based on existing spreadsheets. There is no comparison with any other software. Our goal was to create a very low cost application with the help of experts to share with drilling engineers, technicians, drillers, drilling engineering students and teachers. It is not intended to replace professional software. You can contribute with suggestions for improvements, correcting the English translation, reporting bugs and sharing it with your friends. Features: 1. Easy tool to edit survey stations (add, insert, edit, del) 2. Easy tool to import/export well planning and survey stations using CSV text format (well planning up to 20 sections) 3. 2D and 3D well plotting (vertical section and plan view) 4. Easy tool for interpolation calculations between two survey stations 5. Dynamic visualization of the interpolation parameters in the plot 6. Ability to work with data files (editing locally and sharing on iCloud) 7. Sharing data files with other applications in our portfolio (Directional Drilling, Directional Well Planning and Multilateral Directional Wells).

Verdict
The clearest difference is price: NORO at Free against Directional Well Survey's $14.99. Directional Well Survey's advantage is update cadence (every 18 months vs every 66 months) and iOS requirement (11.0 vs 13.0). On ads, in-app purchases and device support there is nothing between them.
