Investigation of Interactions between Gas Hydrates and Several Other Flow Assurance Elements

Flow assurance is a critical task during oil/gas production, especially in deep-water or cold weather conditions. It involves effectively handling many solid deposits, such as, hydrates, asphaltene, wax, scale, and naphthenates. Because these deposition elements can coexist, evaluating and addressing each problem in isolation may be inefficient and risky. Instead, a comprehensive approach needs to be sought to take into account the impact of one element on the others. In this work, experiments were conducted to systematically investigate how gas hydrates are related to other flow assurance factors and how these interactions could affect the performance of antiagglomerate hydrate inhibitors (AAHI). It was demonstrated that one type of solid precipitate can promote and exacerbate others. It was also shown that the elimination of one issue can alleviate other associated risks.
