How to Calculate and Solve for Reservoir Radius and Well Spacing | The Calculator Encyclopedia

The image above represents the reservoir radius.

To compute for the reservoir radius, one essential parameter is needed and this parameter is Well Spacing (A).

The formula for calculating the reservoir radius:

re = √[43560A  / π]

Where;

re = Reservoir Radius
A = Well Spacing

Let’s solve an example;
Given that the well spacing of an reservoir radius is 42. Find the reservoir radius?

This implies that;

A = Well Spacing = 42

re = √[43560A  / π]
re = √[43560 x 42 / π]
re = √[1829520 / π]
re = √582354.3
re = 763.12

Therefore, the reservoir radius is 763.12 ft.

Calculating the well spacing (A) when the Reservoir Radius is Given.

A = π x re2 / 43560

Where;

A = Well Spacing
re = Reservoir Radius

Let’s solve an example;
Find the well spacing when the reservoir radius is 60.

This implies that;

re = Reservoir Radius = 60

A = π x re2 / 43560
A = π x 602 / 43560
A = π x 3600 / 43560
A = 11309.73 / 43560
A = 0.259

Therefore, the well spacing is 0.259.
