Wellbore Hydraulics Optimizer
Optimize wellbore hydraulics, ECD, and pressure profiles for safe drilling operations
What You Can Do
You can input well geometry, drilling fluid properties, and operational parameters to rapidly calculate equivalent circulating density (ECD), analyze pressure profiles, and identify hydraulic risks. Claude evaluates mud weight windows, predicts circulation losses, and recommends flow rate and fluid property adjustments to maintain wellbore stability while minimizing nonproductive time during complex well sections.
Features
Computes equivalent circulating density for trip procedures, connections, and static conditions across deviated and horizontal wellbores
Maps static and dynamic pressure gradients against pore pressure and fracture gradients to identify safe operational windows
Identifies high-risk formations based on pressure margins and recommends mud weight adjustments to prevent losses
Evaluates impact of pump rate changes on pressure response and ECD to balance hydraulic efficiency with wellbore stability
Analyzes rheology, density, and thermal effects on pressure profiles and recommends fluid modifications
Uses pressure analysis to suggest optimal casing setting depths with appropriate safety margins
Handles complex geometries including deviated and horizontal sections for accurate pressure and loss predictions
Generates hydraulics-optimized protocols for difficult well sections with historical loss patterns
Example Output
Example 1: ECD Calculation for Connection
Input: Well depth 3,500 m TVD, 15° deviated section, mud weight 1.42 sg, flow rate 350 gpm
Output:
- Static ECD at shoe: 1.48 sg
- ECD during circulation: 1.62 sg
- Margin to fracture gradient (1.75 sg): 0.13 sg ✓
- Recommended connection ECD limit: 1.58 sg
- Pressure at bit during circulation: 385 bar
Example 2: Loss Zone Risk Assessment
Input: Narrow pressure window (1.38–1.58 sg), formation with history of losses at 2,800 m
Output:
- Identified risk zone: 2,750–2,850 m
- Current mud weight safety margin: 0.04 sg below fracture gradient
- Recommended action: Reduce flow rate from 400 to 300 gpm to lower ECD by 0.08 sg and restore margin
- Alternative: Add viscosifier to improve cuttings transport without ECD increase

You can rapidly integrate multi-parameter geochemical datasets—Rock-Eval pyrolysis, biomarker distributions, stable isotopes, and molecular compositions—into coherent petroleum system interpretations. The skill transforms raw analytical parameters (Tmax, S2, biomarker ratios, δ13C values) into subsurface understanding of source rock potential, thermal history windows, depositional environments, and charge timing relative to trap formation. You'll identify thermal maturity stages, distinguish multiple source intervals in multi-sourced basins, and flag analytical anomalies that suggest contamination or stratigraphic mixing.

You can perform comprehensive wellbore hydraulics analysis by inputting well geometry, fluid properties, and operational parameters. Claude calculates pressure drops across open hole and cased hole sections, determines equivalent circulating density (ECD) for narrow margin windows, identifies flow regime transitions, and provides optimization recommendations that balance ROP, hole cleaning, and well control margins. This enables you to validate designs, troubleshoot pressure anomalies, and make data-driven adjustments to flow rates and drilling fluid specifications before issues impact operations.
