SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill helps petroleum engineers interpret well test data to understand reservoir properties like permeability, skin, and flow regimes, crucial for optimizing production and well performance.

Core Features & Use Cases

  • Drawdown Analysis: Calculates pressure behavior during production using the exponential integral solution.
  • Buildup Analysis: Interprets pressure buildup tests using Horner plots to determine permeability and skin.
  • Derivative Analysis: Identifies flow regimes (radial, linear, boundary effects) using the Bourdet pressure derivative.
  • Use Case: A well shows declining production. Use this Skill to analyze its recent buildup test data to diagnose if the issue is reservoir depletion or near-wellbore damage (high skin).

Quick Start

Analyze the provided well test data to determine reservoir permeability and skin factor.

FAQPage Schema
How do I calculate permeability and skin factor from well test data?

Analyze pressure buildup test data using Horner plots to calculate reservoir permeability and skin factor. This Skill interprets pressure transient data to diagnose whether production decline stems from near-wellbore damage or reservoir depletion.

What is a Bourdet derivative used for in pressure transient analysis?

The Bourdet derivative identifies flow regimes like radial, linear, and boundary effects in pressure transient analysis. This Skill computes Bourdet pressure derivatives to diagnose reservoir behavior from drawdown and buildup well test data.

How do I interpret pressure buildup tests to diagnose declining production?

Interpret pressure buildup tests using Horner plots to diagnose declining production caused by near-wellbore damage or reservoir depletion. This Skill analyzes well test data to calculate skin factor and identify the underlying production issue.

Can I perform well test analysis using Python for numerical calculations?

Yes, you can perform well test analysis using Python for numerical calculations and data processing. This Skill utilizes Python modules to compute exponential integral solutions, Horner plots, and wellbore storage calculations for reservoir engineering.

Does pressure transient analysis include wellbore storage calculations?

Yes, pressure transient analysis includes wellbore storage calculations to accurately interpret drawdown and buildup tests. This Skill implements these calculations alongside exponential integral solutions to determine permeability and skin factor.

What is the best way to identify flow regimes from well test pressure data?

The best way to identify flow regimes from well test pressure data is by analyzing the Bourdet pressure derivative. This Skill calculates derivatives to distinguish radial, linear, and boundary effects during pressure transient analysis.
