## Description

This MCP server provides specialized economic decision-support tools for offshore oil and gas development. It allows users to evaluate the trade-offs between connecting a new field to existing infrastructure (tieback) or building a dedicated facility (standalone). The server includes tools to `compare_development_options` by calculating Net Present Value (NPV), `calculate_breakeven_distance` to find the critical distance where development strategies shift, `validate_host_capacity` to ensure production profiles fit within host constraints, and `estimate_operational_costs` to model lifecycle OPEX including host tariffs.

## Tools

### validate_host_capacity
Verifies if tieback is physically feasible given host capacity

### calculate_breakeven_distance
Calculates the distance where tieback becomes less economical than standalone

### compare_development_options
Compares NPV for tieback vs standalone development

### estimate_operational_costs
Calculates total lifecycle OPEX for both scenarios

## Prompt Examples

**Prompt:** 
```
Compare the NPV for a field with 100M barrels, 20km distance, a production profile of {"annualRates": [10, 10, 5]}, standalone CAPEX of 500, tieback CAPEX of 100, tariff of 2, capacity of 15, and 10% discount rate.
```

**Response:** 
```
The preferred option is the tieback development with an NPV of 450.2 million, compared to the standalone NPV of 380.5 million.
```

**Prompt:** 
```
Is a tieback feasible for a production profile of {"annualRates": [20, 15, 10]} with a host capacity limit of 18?
```

**Response:** 
```
No, the tieback is not feasible because the peak production in year 1 (20) exceeds the host capacity limit of 18.
```

**Prompt:** 
```
What is the break-even distance for a field with 50M barrels, standalone CAPEX of 400, tieback CAPEX per km of 5, tariff of 1, capacity of 10, and 8% discount rate?
```

**Response:** 
```
The break-even distance is 35.4 km. Beyond this distance, a standalone facility becomes the more economical choice.
```

## Frequently Asked Questions

**How does the tool handle host capacity constraints?**
The `validate_host_capacity` tool checks the production profile against the host limit. If any annual production exceeds the limit, the tieback is flagged as infeasible.

**What is the break-even distance?**
It is the distance where the cost of the tieback pipeline equals the cost of a standalone facility, which can be found using `calculate_breakeven_distance`.

**Does the NPV calculation include host tariffs?**
Yes, when using `compare_development_options`, the tieback NPV accounts for the host tariff per barrel produced.
