Mud logging

Gas-ratio interpretation from mud-logging data — component ratios and fluid typing that give real-time hydrocarbon indicators while drilling.

Gas chromatography

• Chromatographic component ratios (C1–C5) for in-situ fluid characterisation.
• Ratio analysis to detect and rank hydrocarbon shows.

Fluid typing

• Pixler and Haworth methods — distinguish oil, gas and condensate shows.
• Fluid type by mud gas — classification of the reservoir fluid from the gas response.
• Real-time hydrocarbon indicators delivered while drilling.

This page summarises the Mud-logging (GTI) section of the Wellbore.AI / Gamma technical manual.
