Question

If the shrinkage factor of a crude oil is 0.7, its formation volume factor is ________. \text{[round off to 1 decimal place]}

Hint:

The formation volume factor is the inverse of the shrinkage factor for crude oil.

Answer 1

Correct Answer: 1.4

The formation volume factor \( B_o \) of crude oil is related to the shrinkage factor \( S_f \) by the following formula:
\[ B_o = \frac{1}{S_f} \] where: - \( S_f = 0.7 \) is the shrinkage factor.
Substituting the value of \( S_f \): \[ B_o = \frac{1}{0.7} = 1.42857. \] Rounding off to one decimal place: \[ B_o = \boxed{1.4}. \]
