Geological true thickness calculator

Calculate true bed thickness with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use true bed thickness to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

True bed thickness (m)

Intercept length × absolute dot(traverse unit vector, plane normal).

Symbols and units

Assumptions & limits

Assumptions & limits

  • Apparent thickness, bed and traverse geometry. Returns Corrected bed thickness. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Observed traverse intercept length (m): minimum 1e-12, maximum 1000000000000.0. Plane strike (degrees): minimum 0, maximum 360. Plane dip (degrees): minimum 0, maximum 90. Traverse trend (degrees): minimum 0, maximum 360. Traverse plunge down (degrees): minimum -90, maximum 90.
