The general form of objective function for production targets optimisation is given by:
G(t) = \sum_{p=1}^{N^{\uparrow}_P} \left[ R_O \cdot q^{\uparrow}_{O, p} + R_G \cdot q^{\uparrow}_{G, p} \right] - \sum_{p=1}^{N^{\uparrow}} C^{\uparrow}_{L,p} \cdot q^{\uparrow}_{L, p} - \sum_{p=1}^{N^{\uparrow}} C^{\uparrow}_{O,p} \cdot q^{\uparrow}_{O, p} - \sum_{p=1}^{N^{\uparrow}} C^{\uparrow}_{G,p} \cdot q^{\uparrow}_{G, p} - \sum_{p=1}^{N^{\uparrow}} C^{\uparrow}_{W,p} \cdot q^{\uparrow}_{W, p} - \sum_{i=1}^{N^{\downarrow}_W} C^{\downarrow}_{W,j} \cdot q^{\downarrow}_{W, i} - \sum_{j=1}^{N^{\downarrow}_G} C^{\downarrow}_{G,j} \cdot q^{\downarrow}_{G, j} \rightarrow \rm max |

This can be rewritten in terms of sandface flowrates:
G = \sum_{p=1}^{N^{\uparrow}_P} G^{\uparrow}_{t,p} \cdot q^{\uparrow}_{t, p} - \sum_{i=1}^{N^{\downarrow}_W} G^{\downarrow}_w \cdot q^{\downarrow}_{w, i} - \sum_{j=1}^{N^{\downarrow}_G} G^{\downarrow}_g \cdot q^{\downarrow}_{g, j} \rightarrow \rm max |
