This report summarizes the findings of a six month National Energy Technology Laboratory (NETL)-led review of the current state of knowledge regarding research needs and potential knowledge gaps as they relate to current-day cementing practices and conditions of offshore wells. This review incorporated information from scientific and technical literature, feedback from various industry professional organizations, input directly from industry experts associated with the cementing of offshore wells, as well as results from a two-day workshop. Research needs were evaluated in terms of the development of improved tests needed for operators and regulators, filling key data gaps needed in assessing risks or potential failures, and key elements in quality control that could negatively impact performance.
