Book Description
Deposição de parafinas de alto peso molecular nas paredes internas de linhas submarinas de produção e transporte é um dos problemas críticos encontrados pela indústria de petróleo. O acúmulo de material depositado podeocasionar um aumento na potência de bombeamento requerida, diminuição da vazão ou mesmo o bloqueio completo da linha com conseqüente perda de produção e de investimentos. O presente trabalho realizou uma análise detalhada da literatura sobre deposição de parafina onde concluiu-se que não existe evidência experimental suficiente para definir qual o mecanismo básico responsável pela deposiçãodos cristais de parafina. Baseado no resultado da revisão bibliográfica foram realizados estudos experimentais e simulações numéricas sobre a deposição de parafina no interior de dutos. O trabalho foi direcionado para a condução de estudos de caráter fundamental onde buscou-se, através de experimentos simples, tentar contribuir para o melhor entendimento dos mecanismos de deposição de parafina. Experimentos com deposição em cavidades contendo fluido estagnado e em escoamento laminar produziram resultados para a evolução temporal e espacial da frente de deposição ainda não disponíveis na literatura. O modelo numérico puramente difusivo proposto no presente trabalho para deposição em cavidades com fluido estagnado, subestima os valores de espessura de depósito quando comparados com os valores experimentais observados. As observações realizadas não foram suficientes para corroborar a hipóteseque a deposição de parafina é devida somente ao mecanismo de difusão molecular.

Book Description
As oil and gas production moves to deeper and colder water, subsea multiphase production systems become critical for economic feasibility. It will also become increasingly imperative to adequately identify the conditions for paraffin precipitation and predict paraffin deposition rates to optimize the design and operation of these multiphase production systems. Although several oil companies have paraffin deposition predictive capabilities for single-phase oil flow, these predictive capabilities are not suitable for the multiphase flow conditions encountered in most flowlines and wellbores. For deepwater applications in the Gulf of Mexico, it is likely that multiphase production streams consisting of crude oil, produced water and gas will be transported in a single multiphase pipeline to minimize capital cost and complexity at the mudline. Existing single-phase (crude oil) paraffin deposition predictive tools are clearly inadequate to accurately design these pipelines because they do not account for the second and third phases, namely, produced water and gas. The objective of this program is to utilize the current test facilities at The University of Tulsa, as well as member company expertise, to accomplish the following: enhance our understanding of paraffin deposition in single and two-phase (gas-oil) flows; conduct focused experiments to better understand various aspects of deposition physics; and, utilize knowledge gained from experimental modeling studies to enhance the computer programs developed in the previous JIP for predicting paraffin deposition in single and two-phase flow environments. These refined computer models will then be tested against field data from member company pipelines. The following deliverables are scheduled during the first three projects of the program: (1) Single-Phase Studies, with three different black oils, which will yield an enhanced computer code for predicting paraffin deposition in deepwater and surface pipelines. (2) Two-Phase Studies, with a focus on heat transfer and paraffin deposition at various pipe inclinations, which will be used to enhance the paraffin deposition code for gas-liquid flow in pipes. (3) Deposition Physics and Water Impact Studies, which will address the aging process, improve our ability to characterize paraffin deposits and enhance our understanding of the role water plays in paraffin deposition in deepwater pipelines. As in the previous two studies, knowledge gained in this suite of studies will be integrated into a state-of-the-art three-phase paraffin deposition computer program.

Book Description
With millions of kilometres of onshore and offshore oil and gas pipelines in service around the world, pipelines are the life's blood of the world. Notorious for disrupting natural gas production or transmission, the formation of natural gas hydrates can cost a company hundreds of millions and lead to catastrophic equipment breakdowns and safety and health hazards. Written by an international group of experts, Natural Gas Hydrates in Flow Assurance provide an expert overview of the practice and theory in natural gas hydrates, with applications primarily in flow assurance. Compact and easy to use, the book provides readers with a wealth of materials which include the key lessons learned in the industry over the last 20 years. Packed with field case studies, the book is designed to provide hands-on training and practice in calculating hydrate phase equilibria and plug dissociation. In addition readers receive executable programs to calculate hydrate thermodynamics. - Case studies of hydrates in flow assurance - The key concepts underlying the practical applications - An overview of the state of the art flow assurance industrial developments
