4.2 Pipeline Network Optimization
In this optimization problem, we assume that gathering stations 18, 37, 43, and 44 would
have new production capacity from new blocks connected. The gas flow from upstream
is raised to 100, 150, 150 and 200 × 10 4 m 3 /d. Hence, new pipelines and CSs need to
be constructed in the original gathering system for further development of the gas field.
The parameters of the two-stage hybrid algorithm are shown in Table 3.
