Abstract
Systems and methods facilitate and automate well abandonment procedures. In an embodiment, well field data for a plurality of wells is categorized into well types. An inspection set of wells, including wells of each type, is determined from the entire plurality of wells. Inspection data is collected for each well type, including environmental, regulatory, and well condition data. The inspection data is extrapolated onto wells with similar types for the entire filed and analyzed. The analysis may include determining an optimal sequence of well abandonment activities, and an estimate of costs for abandoning each well, all wells of each type, and the entire well field. In an embodiment, a risk assessment analysis is performed and may include an analysis of factors that may change the cost of abandoning the well field or a sequence of well abandonment activities.
