Dataset for estimating occurrence probability of causation for plugged, abandoned and decommissioned oil and gas wells

The data provides an alternative source for obtaining the failure data to conduct a probabilistic risk analysis of abandoned and decommissioned wells. The datasets were obtained through a plugging and abandonment workshop involving 10 engineers and academics with considerable knowledge of abandoned well safety issues and field experience.本数据集为开展废弃井与退役井的概率风险分析提供了失效数据的替代获取渠道。该数据集通过一场封堵与弃置工作坊采集所得，共有10名深谙废弃井安全问题且具备丰富现场经验的工程师与学者参与其中。
