Abstract
A method of identifying a location of gas breakthrough within a completed production well includes: obtaining production composition data and/or tracer data from the production well; analysing the production composition data and/or tracer data to determine whether gas breakthrough has occurred within the production well; and in response to determining that gas breakthrough has occurred within the production well, examining mud-gas data collected during drilling of the production well to identify a gas breakthrough location within the well where the gas breakthrough has occurred.
