Casing Collapse Pressure Calculator

Quick Answer

The casing collapse pressure calculator computes minimum casing collapse pressure from the input values you provide.

Result Interpretation

Each output is evaluated from the deterministic expression shown above; no approximations are applied.

Worked Example

Verified calculation

Given:

E = 29500000
t = 0.25
D_o = 10

Expected Result:

out_minimum_casing_collapse_pressure = 0.13576543538546

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

Formula / Method

Minimum Casing Collapse Pressure: ((((2 * 2.718281828459) * t) / D_o) - ((0.875 * (2.718281828459 * pow(t, 2))) / pow(D_o, 3)))
