Downhole intervention operation optimization

A method performed by a system for generating an intervention program for a downhole formation, the system having a drill string operable within the downhole formation to drill a borehole through the formation, and a control unit arranged to control the drill string and configure to perform method steps, the method comprising:

• collecting mud-gas ratio data during a drilling operation, wherein the drilling operation forms a borehole through the formation;
• generating zone characterization of one or more zones along the borehole based on the collected mud-gas ratio data;
• defining targeted zones of the one or more zones along the borehole;
• generating a treatment characterization for each targeted zone based on the collected mud-gas ratio data;
• and
• generating an intervention treatment design based on the targeted zones and associated treatment characterizations.
