SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill automates the preliminary sizing and design of essential oil and gas surface production facilities, streamlining the conceptual design process for engineers.

Core Features & Use Cases

  • Separator Sizing: Calculate dimensions for two-phase and three-phase separators based on gas capacity and liquid retention.
  • Dehydration Design: Determine TEG circulation rates and reboiler duty for glycol dehydration units.
  • Compression Sizing: Estimate adiabatic horsepower, discharge temperatures, and stages needed for compression systems.
  • Wellhead Backpressure Analysis: Evaluate the impact of surface backpressure on gas well deliverability.
  • Use Case: A petroleum engineer needs to size a test separator and a dehydration unit for a new well. They can use this Skill to get initial equipment dimensions and flow rates.

Quick Start

Use the surface-facilities skill to size a two-phase separator for 10 MMscfd of gas at 100°F and 50 psia, with a liquid rate of 200 bpd.

Frequently Asked Questions about surface-facilities

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I size a two-phase separator for oil and gas production?▼

Separator sizing uses the Souders-Brown equation to calculate dimensions based on gas capacity and liquid retention. Input gas flow rates, operating pressure, and temperature to estimate vessel dimensions for two-phase or three-phase separators.

How do I calculate TEG circulation rate and reboiler duty for glycol dehydration?▼

Glycol dehydration design calculates TEG circulation rates and reboiler duty for gas dehydration units. Input your gas flow rate and water content requirements to determine the necessary glycol circulation and heat duty.

How do I estimate compression horsepower and discharge temperature for gas systems?▼

Compression sizing estimates adiabatic horsepower, discharge temperatures, and required compression stages. Input gas flow rates and pressure ratios to calculate the preliminary compression system requirements.

Can I analyze wellhead backpressure effects on gas well deliverability?▼

Wellhead backpressure analysis evaluates the impact of surface backpressure on gas well inflow performance. Calculate how varying surface pressures affect gas well deliverability to optimize production rates.

What equations are used for preliminary surface facility design calculations?▼

Preliminary surface facility design utilizes the Souders-Brown equation for separator sizing, Stokes' law for liquid droplet settling, and adiabatic compression principles for compression system calculations.

Is this Skill suitable for detailed mechanical design of surface facilities?▼

This Skill is designed for preliminary sizing and conceptual design of surface facilities, not detailed mechanical design. Use it to get initial equipment dimensions and flow rates for separators, dehydration units, and compressors.
