Lost Oil in Migration
Oil Lost in Migration formula
STB (stock tank barrel) is the same volume defined at some surface standard conditions in a stock tank, which are usually 60°F and 14.7 psi. |

\( n_i \;=\; 7758 \cdot \dfrac{ A \cdot h \cdot n \cdot S }{ B_o } \) (Lost Oil in Migration) \( A \;=\; \dfrac{n_i \cdot B_o }{ 7758 \cdot h \cdot n \cdot S }\) \( h \;=\; \dfrac{n_i \cdot B_o }{ 7758 \cdot A \cdot n \cdot S } \) \( n \;=\; \dfrac{n_i \cdot B_o }{ 7758 \cdot A \cdot h \cdot S } \) \( S \;=\; \dfrac{n_i \cdot B_o }{ 7758 \cdot A \cdot h \cdot n} \) \( B_o \;=\; \dfrac{7758 \cdot S \cdot A \cdot h \cdot n }{ n_i } \) |
