Distance from observation well to image well Solution

Follow our step by step solution on how to calculate Distance from observation well to image well?

FIRST Step Consider the formula

r i = r r \cdot \sqrt{\frac{t i}{t r}}

Next Step Substitute values of Variables

∴

r i = 26m \cdot \sqrt{\frac{200min}{150min}}

Next Step Convert Units

∴

r i = 26m \cdot \sqrt{\frac{12000s}{9000s}}

Next Step Prepare to Evaluate

∴

r i = 26 \cdot \sqrt{\frac{12000}{9000}}

Next Step Evaluate

∴

r i = 30.0222139978605m

LAST Step Rounding Answer

∴

r i = 30.0222m
