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 global consumption of fossil fuels such as oil increases, previously abundant sources have become depleted or plagued with obstructions. Asphaltene deposition is one of such obstructions which can significantly decrease the rate of oil production. This book offers concise yet thorough coverage of the complex problem of asphaltene precipitation and deposition in oil production. It covers fundamentals of chemistry, stabilization theories and mechanistic approaches of asphaltene behavior at high temperature and pressure. Asphaltene Deposition: Fundamentals, Prediction, Prevention, and Remediation explains techniques for experimental determination of asphaltene precipitation and deposition and different modeling tools available to forecast the occurrence and magnitude of asphaltene deposition in a given oil field. It discusses strategies for mitigation of asphaltene deposition using chemical inhibition and corresponding challenges, best practices for asphaltene remediation, current research, and case studies.

Book Description
The precipitation and deposition of solids are a major challenge in the production of oil and gas. Flow assurance solids are formed because of unavoidable changes in temperature, pressure and composition of the oil-gas-water flowstream, from reservoir conditions to processing conditions. The advent of subsea production and the increased exploitation of heavy crudes have made flow assurance issues dominant in ensuring efficient and safe exploitation of hydrocarbon assets. Five troublesome flow assurance solids are described in the book: asphaltene, paraffin wax, natural gas hydrate, naphthenate and inorganic scale. These big-five solids are presented in stand-alone chapters. Each chapter is designed to be readable without clutter. Derivations of equations and descriptions of supporting details are given in several appendices. The book is intended for professional engineers and natural scientist working in E&P companies, engineering companies, service companies and specialized companies. An understanding of the big-five solids is required throughout the lifetime of oil and gas assets, from early development to abandonment. The technical, safety and environmental risks associated with deposition problems in near-wellbore formations, production tubing, wellhead equipment, flowlines and processing facilities, are relevant for decisions in the oil and gas industry and in outside regulatory and financial entities.

Book Description
With production from unconventional rigs continuing to escalate and refineries grappling with the challenges of shale and heavier oil feedstocks, petroleum engineers and refinery managers must ensure that equipment used with today's crude oil is protected from fouling deposits Crude Oil Fouling addresses this overarching challenge for the petroleum community with clear explanations on what causes fouling, current models and new approaches to evaluate and study the formation of deposits, and how today's models could be applied from lab experiment to onsite field usability for not just the refinery, but for the rig, platform, or pipeline. Crude Oil Fouling is a must-have reference for every petroleum engineer's library that gives the basic framework needed to analyze, model, and integrate the best fouling strategies and operations for crude oil systems. - Defines the most critical variables and events that cause fouling - Explains the consequences of fouling and its impact on operations, safety, and economics - Provides the technical models available to better predict and eliminate the potential for fouling in any crude system
