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.

Verdict

The call

The clearest difference is price: SCR MAXFLO™ at Free against 3D Interpolation's $9.99. SCR MAXFLO™ also leads on update cadence (every 11 months vs every 37 months). 3D Interpolation's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 16.6). On ads and in-app purchases there is nothing between them.
