Worked Example

Verified calculation

Given:

  • Minimum Horizontal Stress = 25000000
  • Overburden Stress = 32000000
  • Poisson's Ratio = 0.25

Expected Result:

  • Borehole Stability Margin = 5800000

Engineering Interpretation:

Under the given input conditions, the calculated result is: Borehole Stability Margin = 5800000 Pa.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.

Frequently Asked Questions

What does this calculator calculate?

The Geomechanical Borehole Stability Margin Calculator estimates Borehole Stability Margin based on the input parameters you provide

Why is minimum horizontal stress important in this calculation?

minimum horizontal stress is directly proportional to borehole stability margin. When you enter minimum horizontal stress in Pa, the calculator uses it in the engineering formula to compute the output

How should I interpret the result borehole stability margin?

The calculator outputs borehole stability margin in Pa. For higher pressures, divide by 1000 to express in kPa, or by 101325 for atmospheres. The result is computed directly from the input values using the defined engineering formula

What units should I use for the inputs?

Enter each value in the units shown next to the input field: Minimum Horizontal Stress (Pa), Overburden Stress (Pa), Poisson's Ratio (dimensionless). Make sure all inputs use the specified units for consistent results

What assumptions does this calculator use?

This calculator uses automatically validated engineering formulas. Results are approximate and should be validated against site-specific conditions, applicable codes, and professional engineering judgment
