Production Network Routing

Use this skill for a quick, public screening of a "reservoir-to-facility" production network: wells flowing through manifolds and flowlines/risers to a host. Given wells with a productivity index and a manifold/flowline layout, it estimates a screening rate per well, aggregates rates by manifold, and rolls up an arrival pressure at the host with a simple pressure-drop gradient. It is intentionally simple and should guide users toward validated NeqSim inflow and multiphase-hydraulics workflows.

When to Use

• When wells, a manifold layout, and a required arrival pressure are available and a first network roll-up is needed.
• When an agent needs to chain reservoir-vs-time screening to a platform arrival-pressure check.
• Before detailed IPR, tubing, and multiphase flowline modelling.

Inputs

• wells: rows of {name, manifold, reservoir_pressure_bara, flowing_bottomhole_pressure_bara, productivity_index_sm3_per_day_bar, tubing_head_pressure_bara}.
• manifolds: rows of {name, flowline_length_km, pressure_gradient_bar_per_km, riser_dp_bar} (riser_dp_bar optional, default 0).
• host_name: name of the receiving host/platform (default HOST).
• required_arrival_pressure_bara: minimum required arrival pressure at the host.

Outputs

• wells: per-well drawdown_bar, rate_sm3_per_day, and flow_warning.
• manifolds: per-manifold total_rate_sm3_per_day, manifold_pressure_bara, flowline_dp_bar, riser_dp_bar, arrival_pressure_bara, arrival_margin_bar, and arrival_warning.
• total_rate_sm3_per_day: aggregated network rate.
• min_arrival_pressure_bara: lowest manifold arrival pressure.
• overall_warning: worst of the well and manifold warnings.
• neqsim_available: whether the optional NeqSim package is importable.
• assumptions: public assumptions and required follow-up.

A separate regulate_flow_from_inlet_pressure entry point screens pressure-regulated multiwell flow from a facility inlet/separator pressure and the reservoir pressures (see "Pressure-Regulated Multiwell / Manifold Flow").
