Calculate Formation Pressure (FP)





Formula

The formula to calculate the Formation Pressure (FP) is:

\[ FP = HSPM + HSPI + SICP \]

Where:

Definition

Example

Let's say the hydrostatic pressure of the mud in the annulus (HSPM) is 1000 psi, the hydrostatic pressure of the influx (HSPI) is 500 psi, and the shut-in casing pressure (SICP) is 200 psi. Using the formula:

\[ FP = 1000 + 500 + 200 = 1700 \]

So, the Formation Pressure (FP) is 1700 psi.

Formation Pressure

Definition: Formation pressure is the pressure within a geological formation, often measured in megapascals (MPa).

Formula: \( P_f = \rho g h \)

Example: \( P_f = 1000 \times 9.81 \times 2000 \)

Base Pressure Calculation for Foundation

Definition: Base pressure is the pressure exerted by a foundation on the underlying soil.

Formula: \( P_b = \frac{W}{A} \)

Example: \( P_b = \frac{50000}{25} \)

Concrete Form Pressure

Definition: Concrete form pressure is the pressure exerted by fresh concrete on the formwork.

Formula: \( P_c = \rho g h \)

Example: \( P_c = 2400 \times 9.81 \times 3 \)

Formation Volume Factor

Definition: The formation volume factor is the ratio of the volume of fluid at reservoir conditions to the volume at standard conditions.

Formula: \( B_f = \frac{V_r}{V_s} \)

Example: \( B_f = \frac{1.2}{1} \)

Plateau Pressure Calculation

Definition: Plateau pressure is the pressure applied to the lungs at the end of inspiration during mechanical ventilation.

Formula: \( P_{plat} = \frac{V_t}{C} + PEEP \)

Example: \( P_{plat} = \frac{500}{50} + 5 \)
