Abstract

A system for selective fluid treatment of formation areas to remove formation damage may include an access module configured to access log data associated with a well. The system may include one or more hardware processors configured to identify a formation area as a treatment candidate area based on at least one of a permeability value associated with the formation area or a porosity value associated with the formation area. The one or more hardware processors may be configured to determine, based on reservoir modelling, a current depth of invasion value associated with the formation area, determine a volume of drilling mud buildup in the formation area based on the current depth of invasion value, and determine a treatment fluid volume value that identifies a volume of treatment fluid for application to the formation area to remove the formation damage from the formation area during a formation damage removal process.
