The image represents the infinite acting period.

To compute the infinite acting period, six essential parameters are needed and these parameters are **permeability (k), porosity (φ), well drainage area (A), viscosity (μ), Dimensionless Time to End of Infinite Acting Period ((t _{DA})_{eia}) and total compressibility (C_{T}).**

The formula for calculating the infinite acting period:

t_{eia} = [^{φ μ CT A} / _{0.000263K}] (t_{DA})_{eia}

Where;

t_{eia} = Infinite Acting Period

K = Permeability

φ = Porosity

A = Well Drainage Area

μ = Viscosity

(t_{DA})_{eia} = Dimensionless Time to End of Infinite Acting Period

C_{T} = Total Compressibility

Let’s solve an example;

Given that the permeability is 21, porosity is 15, well drainage area is 32, viscosity is 26, dimensionless time to end of infinite acting period is 44 and total compressibility is 34.

Find the infinite acting period?

This implies that;

K = Permeability = 21

φ = Porosity = 15

A = Well Drainage Area = 32

μ = Viscosity = 26

(t_{DA})_{eia} = Dimensionless Time to End of Infinite Acting Period = 44

C_{T} = Total Compressibility = 34

t_{eia} = [^{φ μ CT A} / _{0.000263K}] (t_{DA})_{eia}

t_{eia} = [^{15 x 26 x 34 x 32} / _{0.000263 x 21}] 44

t_{eia} = [^{424320 }/ _{0.005523}] 44

t_{eia} = [76827810.972] 44

t_{eia} = 3380423682.78

Therefore, the **infinite acting period **is **3380423682.78 s.**
