To find the number of sections of casing needed to reach the oil reserve, you would divide the total depth of the oil reserve by the length of each casing piece.
The total depth of the oil reserve is 1400 feet, and each casing piece is 32 feet long.
\[ \text{Number of sections} = \frac{\text{Total depth}}{\text{Length of each casing}} \]
\[ \text{Number of sections} = \frac{1400 \, \text{ft}}{32 \, \text{ft}} \]
\[ \text{Number of sections} \approx 43.75 \]
Since you can't have a fraction of a casing section, the crew would need 44 sections of casing to reach the oil reserve.
