Description
verticalIncrement = length*cos(inclination); horizontalIncrement = length*sin(inclination); finalDepth = initialDepth+verticalIncrement.
Geological orientations and component projections require explicit axis, angle and sign conventions. A straight segment or planar-set correction is a geometric model, not an independently measured structure or hazard assessment.
verticalIncrement = length*cos(inclination); horizontalIncrement = length*sin(inclination); finalDepth = initialDepth+verticalIncrement.
When to use this tool
Use Borehole Depth Inclination Vertical Term when checking one supplied geological orientation or displacement projection.
How to use the tool and how it works
- Enter measuredLength, inclinationFromVertical, initialDepth. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read verticalIncrement, horizontalIncrement, finalDepth. Use the output convention below.
Require nonnegative measuredLength and inclinationFromVertical in [0,pi]. verticalIncrement = length*cos(inclination); horizontalIncrement = length*sin(inclination); finalDepth = initialDepth+verticalIncrement.1

}Limitations and assumptions
- Angles are radians from positive-down vertical, so inclinations beyond pi/2 reduce depth. This straight segment has no azimuth and does not reconstruct a curved borehole.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified observations, reference directions and full geometry before interpreting real structures or practical stability.
