“…They account for specific connection structures and limits in the pressure drops by considering friction losses and elevation differences, using simplified linear equations. Also Dbouk et al (2020) optimize the design of gathering pipeline networks paying special attention to topological complexities and using a shortest path algorithm. Nevertheless, all these works are not focused on unconventional production, proposing static formulations that do not account for the continued turn-in-line of new wells over the planning horizon.…”

The optimal design of gathering networks for the unconventional oil and gas production is a relevant problem, particularly with the shale boom. In this work, we address a network design problem in which the main decisions are the location and sizing of tank batteries for oil and gas separation together with the pipeline connections. The goal is to gather the oil, gas and water production from a large number of wellpads, being also possible to install junction nodes to merge the production at some points of the field. One major challenge is due to the steep production decline curves, requiring continued connections of new wells. To address this problem, we develop a complex multiperiod formulation accounting for the varying flows over the planning horizon. We propose an optimization framework to obtain efficient solutions within reasonable computational times. To circumvent the computational burden of a large-scale, nonlinear and non-convex model due to the fluid dynamics of multiphase flows, we propose a solution algorithm based on a bi-level decomposition. Near optimal solutions are found for real-world instances, suggesting that facility planning can considerably improve the economics of unconventional projects.

In this paper, the flow distribution uniformity of parallel tubes with radial inlet is studied. Based on the Fluent simulation module in ANSYS WORKBENCH, the numerical simulation of parallel pipe sets is carried out, and the regularity of flow distribution uniformity of parallel pipe sets at radial inlet under different gas flow rates is obtained. In order to make the obtained law more universal, under the condition of constant simulation conditions, change the inlet position and the number of inlet, through a large number of simulation, get the flow distribution uniformity law under different conditions, and found that these laws have similarity.

The high price of desalination is often considered one of the primary obstacles to making desalinated water a viable option for irrigated agriculture. Relatively little attention has been given to how strategic planning of regional water supplies might contribute to addressing this issue, particularly in leveraging investment in desalination by wealthier sectors to support agricultural communities. The Copiapó valley in Chile has been selected as a case study to investigate this. The study illustrates using modelling how the expansion of the mining and associated investment in desalination can reduce the economic and environmental costs of supplying desalinated water to irrigators. It was observed that the reduction of costs is affected by the degree of expansion in the mining sector, the degree of expansion in the irrigated agriculture sector, and the energy market. With potential expansions, if they invest strategically in creating an optimal water supply network, the marginal costs of producing desalinated water can be reduced to between 1.09 USD/m³ and 2.53 USD/m³ depending on the energy price. This represents a reduction of 58–3%, respectively, compared to the average cost of producing desalinated water under baseline conditions where irrigated desalination is not supported. Results show that foresightful integrated water planning, which accounts for planned expansion in water demand, can result in more realistic costs of irrigating with desalinated water - although subsidy remains a likely requirement. Such integrated water planning would help bridge the gap between the price of desalinated water for irrigation practices. Furthermore, as demonstrated in this study, these practices can minimize the environmental impact of establishing a water conveyance network.
