“…Therefore, in a vertical pipe, drift velocity calculated from constants of synthetic data is 7 times larger than that evaluated using constants from experimental data. Values from experimental data were used in [35] to develop a fast transient solver with a power law method in order to find the pressure drop. The power law method, which is a modified version of that proposed in [40], is a simple formula that can be applied to a wide range of multiphase flows.…”

“…The model of [35] is based on a quasi steady state. Therefore, this approach can not predict fast changes in the flow pattern, and some discrepancies with experimental data are observed in the early stages of the simulation, when temporal changes are more notorious.…”

In this work a review about the most relevant methods found in the literature to model the multiphase flow in pipelines is presented. It includes the traditional simplified and mechanistic models, moreover, principles of the drift flux model and the two fluid model are explained. Even though, it is possible to find several models in the literature, no one is able to reproduce all flow conditions presented in the oil industry. Therefore, some issues reported by different authors related to model validation are here also discussed. ResumenEn este trabajo se presenta una revisión de los métodos más relevantes en la industria del petróleo para modelar el flujo multifásico en tuberías. Se incluyen desde los modelos simplificados hasta los modelos mecanicistas además de explicar los principios de los modelos drift flux y two fluid. Existe una gran cantidad de modelos en la literatura para simular el flujo multifásico en tuberías, empero, ningún modelo es capaz de reproducir todas las condiciones de flujo multifásico presentes en la industria del petróleo. Finalmente, se mencionan algunos temas en los que se requiere más investigación que lleven a simulaciones con resultados más cercanos a los datos de pozos reales.

“…Las tuberías bifásicas están usualmente diseñadas para operar bajo estado estable. no obstante, cuando se inducen cambios en condiciones operacionales tales como tasas de flujo, presiones en el separador; en las tuberías se produce un cambio a estado transiente (Choi et al, 2013). En Colombia, los antecedentes de investigaciones de este tipo son escasos, planteando la necesidad de realizar estudios similares en nuestro territorio.…”

“…Desde ese entonces, la industria ha desarrollado códigos transientes multipropósito tales como OLGa, PLaC, taCite y más recientemente LeDafLOW. estos simuladores normalmente consisten en conjuntos de ecuaciones de conservación de masa, energía y momentum (Choi et al, 2013). uno de los primeros estudios del modelado del flujo tapón fue desarrollado por Dukler y Hubbard (1975).…”

*A quien debe dirigirse la correspondencia RESUMENLos desafíos asociados al fl ujo multifásico son tan antiguos como la industria del petróleo. en muchos campos de crudo y gas con líneas de fl ujo multifásico, la inestabilidad de la producción debido a la presencia de fl ujo intermitente es el principal problema de aseguramiento de fl ujo. en Colombia, los antecedentes de investigaciones de este tipo son escasos, por consiguiente se plantea la necesidad de realizar estudios similares en nuestro territorio. existen razones para creer que diferentes campos nacionales presentan problemas de aseguramiento de fl ujo relacionados con el fl ujo intermitente. el objetivo de este artículo es realizar una recopilación teórica de los estudios principales relacionados con el fl ujo intermitente en operaciones de la industria de Petróleo y Gas, que permita sentar las bases para trabajos posteriores en el área, con respecto a esta temática en el ámbito nacional. este trabajo detalla un estado del arte sobre el fl ujo intermitente, sus características y una revisión exhaustiva de los métodos de simulación existentes en la literatura. adicionalmente, plantea una metodología para realizar estudios de este tipo de fl ujos, al igual que una discusión sobre posibles estrategias de mitigación y su aplicación en campo.Palabras clave: aseguramiento de flujo, flujo Multifásico, flujo tipo tapón, flujo transiente, fenómenos de transporte, facilidades de superfi cie. Characterization and mitigation of slugging flow in oil gathering networks under dynamic conditions ABSTRACTChallenges associated to multiphasic fl ow are as old as the petroleum industry itself. in many oil and gas fi elds with multiphasic fl ow lines, production instability due to severe slugging is their main fl ow assurance issue. in Colombia, the previous works on this matter are rather limited. there are strong reasons to presume the existence of fl ow assurance issues related to severe slugging in many national fi elds. the main purpose of this article is to perform a technical compliance of the most relevant studies related to severe slugging in the Oil and Gas industry operations, which allows to set basis for further works in this area, addressing the matter in the national context. this paper contains a state-of-the-art review on severe slugging, intermittent fl ow, their characteristics, and a thorough revision of the existing numerical simulation methods in literature. in addition, this document proposes a methodology for the realization of similar studies, and a discussion of mitigation strategies and their application on fi eld operations.

Hydrate phase transition may bring hidden dangers for well control safety, even accidents of blowout happen in deep water drilling. Accurate calculation of all the drilling parameters is of great importance for well control safety. In this study, the mathematic models of transient heat transfer and multiphase flow have been established with the consideration of hydrate phase transition. Furthermore, the position where hydrate formation is most likely to occur was predicted with the proposed models, and the factors affecting hydrate formation region were also analyzed. Finally, the analysis of the effect of gas hydrate phase transition on some important parameters in well control, such as the pit gain, gas void fraction, and bottom hole pressure, is presented. The results show that hydrates form near the mud line during the drilling and shut‐in stage, but the hydrate formation region will be narrowed as well killing start. Additionally, the hydrate formation region decreased with the increase of flow rate and increased with the increasing shut‐in time, hydrate inhibitors, and riser insulation are presented to prevent hydrate blockage. More importantly, the gas void fraction and pit gain decrease due to the formation of hydrates, leading to the gas kick early detection not timely and gas kick more “hidden.”
