Flow assurance involves the reliable, continuous and simultaneous transport of liquid crude oil, gas, water and sand from the formation to the processing facilities.
As offshore production ventures into more remote and deeper waters, untreated formation fluids travel longer distances through pipelines, valves and pumping devices before reaching process equipment. Frequently, untreated hydrocarbons are characterised by the presence of more than one phase therefore requiring flow assurance evaluation and analysis during the engineering design stages of the project. Multiphase fluid transport is a complex and challenging issue. Most hydrocarbon formations contain a mixture of liquid crude oil, natural gas and water. Additionally, dislodged sand can be carried with the well fluids. All these components or phases can be simultaneously present during the production process.
BMT has extensive expertise in multiphase flow analysis using Computational Fluid Dynamics (CFD) for oil and gas applications. CFD allows you to perform three-dimensional (3D) simulations of interpenetrating or immiscible fluids that include effects of pressure, temperature and liquid/gas mass transfer in detail. The results of these simulations can be used to provide qualitative evaluation of flow assurance issues such as erosion, slugging and hydrate formation.
BMT’s experience in CFD modelling for the oil and gas sector and providing informed analysis of the data can help designers and operators solve flow problems, extend life of flow lines and ultimately, assure the efficient and reliable delivery of the product.
