Abstract
A method and system is provided that analyzes flow characteristics of return fluid that flows to a surface-located facility during well operations (such as plug mill-out or cleanout/workover operations) in order to characterize local formation properties of the formation. The method and system can be used to characterize a hydraulically-fractured hydrocarbon-bearing formation that is traversed by a well having a number of intervals that are hydraulically isolated from one another by corresponding plugs.

A method for characterizing a hydraulically-fractured hydrocarbon-bearing formation that is traversed by a well having a number of intervals, the method comprising:
- analyzing flow characteristics of return fluid that flows from a particular interval back to a surface-located facility during well operations;
- and
- characterizing at least one local formation property of the hydraulically-fractured formation adjacent the particular interval based on such flow characteristics.
A method for characterizing a hydraulically-fractured hydrocarbon-bearing formation that is traversed by a well having a number of intervals, the method comprising:
- analyzing flow characteristics of return fluid that flows from at least one interval back to a surface-located facility during well operations;
- and
- characterizing at least one property relating to solids production of one or more intervals based on such flow characteristics.
