neqsim-integrated-well-planning

Integrated Well Planning

One repeatable workflow that turns reservoir information, fluid data, well requirements and facility constraints into a traceable well-design proposal, executable models, professional drawings and a well-planning report. It supports oil producers, gas and gas-condensate producers, water injectors and gas injectors, onshore, on platforms and subsea. The agent well-planning-engineer coordinates the study; this skill defines the schemas, methods, calculation tools, checks, drawing templates and report structure. The drilling and casing design module is the required skill neqsim-well-design-study.

The skill separates three things that must never be mixed up: implemented calculations (NeqSim classes with tests), screening estimates (executable but approximate or uncalibrated) and assessments not performed (they need an external tool or specialist; the skill then produces an interface specification, never a number). That separation is the capability ledger below and is printed in every report.

When to Use

• A well concept must be sized or compared: tubing size, wellhead/host back pressure, gas lift, completion arrangement, injection pressure and duty.
• A reservoir fluid and an IPR/injectivity basis exist and the question is deliverability, injectivity, temperatures, phase behaviour, hydrate margin and the operating envelope.
• A study needs a source/assumption register, a standards register, barrier schematics, A3 drawings, a decision/action log and a report that states what was and was not calculated.
• A hand-off to or from another agent is needed (VFP tables, trajectory, host constraints, PVT, cost/profile, flow-assurance requirements, integrity inputs).
• Do not use it for final design, rig-ready programmes, relief-well work, regulatory compliance statements or reservoir recovery/value estimates.

Inputs

The planning basis (iwp_planning_basis.v1, YAML or JSON, template: templates/planning_basis_template.yaml). Ranges are {low, base, high}; low is the pessimistic outcome, high the optimistic one (skin, water cut and host pressure are therefore taken from the opposite end of their range in the low case).
