About

3D Interpolation

Calculate key directional drilling parameters like TVD, coordinates, and displacement. This tool aids drilling engineers and students in oil well directional drilling by interpolating survey data.

Highlights
  • Calculate TVD, N/S, E/W coordinates
  • Determine Horizontal Displacement
  • Calculate Dog-Leg Severity
  • Measure Build-Up Rate
  • Calculate Turn Rate
  • Interpolate parameters between survey stations

The 3D Interpolation provides an useful tool to calculate projections TVD (True Vertical Depth), N/S and E/W coordinates, Horizontal Displacement, Dog-Leg Severity, Build-Up Rate (Angle Rate, Intensity) and Turn Rate and also the Interpolation of these parameters between two well planning sections or survey stations defined by Measured Depth, Inclination and Azimuth as entry parameters in the directional drilling of oil wells. Calculations Method: Minimum Curvature Length Units: Foot and Meter (Metre) Intensity Units: degree/100ft, degree/10m, degree/30m and degree/100m Our goal was to create a low-cost application with the help of experts to share with drilling engineers, technicians, drillers, students and teachers of drilling engineering. You can contribute with suggestions for improvements, correcting the translation to english, reporting bugs and sharing it with your friends.

E-JETS Virtual Panel App The E-JETS Virtual Panel App is a powerful self-study tool designed to help pilots prepare for initial or recurrent E-JETS training. By simulating cockpit functionality, it allows pilots to become familiar with every panel, switch, and system, significantly reducing study time and boosting training efficiency. Exclusive Feature – Full Interactive Electrical Diagram (Available on iPad version only) The interactive electrical diagram helps pilots understand the E-JETS electrical system by manipulating switches and visually analyzing real-time results, offering a realistic and engaging way to learn both normal and abnormal configurations. ------------------------------- Key Features 1,100+ Fully Functional Buttons with explanations, images, and references (and growing). Pan and Zoom capabilities for precise navigation. Full Interactive Electrical Diagram for realistic system training. Detailed E170 / E175 / E190 button explanations. Memory Items – Fast search, edit, add, and delete capabilities. Limitations – Fast search, edit, add, and delete capabilities. Definitions – Fast search, edit, add, and delete capabilities. EICAS Message List – Fast search tool. High-fidelity cockpit images for an authentic experience. 260+ FMS screens to practice navigation and setup. Dark Mode for low-light training environments. Save your notes and keep them safe, even when your device is powered off. Included Virtual Interactive Panels This version now includes 45 interactive panels, such as: E190 Status Synoptic E170/175 Status Synoptic Electrical Synoptic Hydraulic Synoptic ECS Synoptic Controls Synoptic Fuel Synoptic TCAS Map Overlay EGPWS Display on MFD HSI (Full Compass, ARC, ARC Mode 2) Weather Radar Displays (MFD & PFD) Airspeed, Vertical Speed, and Altitude Tapes ADI (Annunciations, Takeoff, Failures, Miscompares) Flight Mode Annunciations MCDU Basic Functions (Detailed functions coming soon) Horizontal and Vertical Profiles Full EICAS Functions Thrust Lever Buttons DVDR (Universal) Reinforced Door Panel Attendant Rainbow Lights Engine Schematics Glareshield Lights Panel Cockpit Lights Control Panel Passenger Signs Panel External Lights Panel Pressurization Panel Passenger Oxygen Panel Lavatory Fire ---------------------------------- Why Pilots Love E-JETS Virtual Panel Train anytime, anywhere Reduce preparation time before recurrent or type-rating checks. Gain hands-on understanding of cockpit workflows and systems. Constant updates with new interactive content. ---------------------------------- Note: Cockpit configurations vary slightly by aircraft. The panels, buttons, and switches in this app represent a specific configuration from the E-JETS family. This app includes complete information for the E170, E175, and E190 models — all in one place.

Verdict

The call

The clearest difference is review sentiment: E at 80% against 3D Interpolation's 0%. E also leads on update cadence (every 3 months vs every 37 months) and chart position (#171 vs unranked). 3D Interpolation's advantage is price ($9.99 vs $19.99) and iOS requirement (12.0 vs 14.0). On ads, in-app purchases, monetization model and device support there is nothing between them.
