Abstract
The thermal industry needs to find ways of managing various financial risks and the high standards to account for the harsh conditions of the Steam-Assisted Gravity Drainage (SAGD) operations, resulting from high temperatures, mechanical loads, geomechanical disturbance, exposure to caustic and corrosive environments and therefore the challenges to intermediate casing designs that lead to failures. An exploratory and a frequency analysis of 2,270 reported thermal failures from the Oil Sands in Alberta, Canada, together with a review of their evolution and the relationship between the failure modes, rates, field/well conditions and equipment specifications helped as foundation of the proposed step-by-step guidance to a high-robust reliability model called Reliability-Based Design Assessment (RBDA). To tackle uncertainty and variability, the model includes the identification of the top influential parameters that affect the structural adequacy of the intermediate casing applied to a case study that encompasses connection fatigue as a failure mechanism.
