Available in PDF, EPUB and Kindle. Book excerpt: Wax deposition is an intrinsic problem existing in the production and transportation of waxy crude oil. In the oilfield, non-metallic pipe especially polyethylene pipe has been widely used to solve corrosion problems. However, few experimental studies focused on wax deposition in polyethylene pipes in recent decades. In the present research, a series of polyethylene (PE) and stainless steel (SS) flow-loop experiments with waxy crude oil were performed to investigate the variation of wax deposit thickness under the laminar flow regime. Unlike the SS pipe, it was found that the deposit layer was not formed in the first few hours for PE pipe. The effects of surface roughness and free energy were analyzed and employed to elucidate the deposition delay for PE pipe. Besides, the difference of heat transfer characteristics between the SS pipe and PE pipe also influences the formation of wax deposit layer. The comparisons and findings of wax deposition between the two kinds of pipes have provided a significant reference for the application of non-metallic pipe in the oilfield.

This book was released on 2023-03-11 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is useful to flow assurance engineers, students, and industries who wish to be flow assurance authorities in the twenty-first-century oil and gas industry. The use of digital or artificial intelligence methods in flow assurance has increased recently to achieve fast results without any thorough training effectively. Generally, flow assurance covers all risks associated with maintaining the flow of oil and gas during any stage in the petroleum industry. Flow assurance in the oil and gas industry covers the anticipation, limitation, and/or prevention of hydrates, wax, asphaltenes, scale, and corrosion during operation. Flow assurance challenges mostly lead to stoppage of production or plugs, damage to pipelines or production facilities, economic losses, and in severe cases blowouts and loss of human lives. A combination of several chemical and non-chemical techniques is mostly used to prevent flow assurance issues in the industry. However, the use of models to anticipate, limit, and/or prevent flow assurance problems is recommended as the best and most suitable practice. The existing proposed flow assurance models on hydrates, wax, asphaltenes, scale, and corrosion management are challenged with accuracy and precision. They are not also limited by several parametric assumptions. Recently, machine learning methods have gained much attention as best practices for predicting flow assurance issues. Examples of these machine learning models include conventional approaches such as artificial neural network, support vector machine (SVM), least square support vector machine (LSSVM), random forest (RF), and hybrid models. The use of machine learning in flow assurance is growing, and thus, relevant knowledge and guidelines on their application methods and effectiveness are needed for academic, industrial, and research purposes. In this book, the authors focus on the use and abilities of various machine learning methods in flow assurance. Initially, basic definitions and use of machine learning in flow assurance are discussed in a broader scope within the oil and gas industry. The rest of the chapters discuss the use of machine learning in various flow assurance areas such as hydrates, wax, asphaltenes, scale, and corrosion. Also, the use of machine learning in practical field applications is discussed to understand the practical use of machine learning in flow assurance.
Download or read book Evaluation of Wax Deposition and Its Control During Production of Alaska North Slope Oils written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to increasing oil demand, oil companies are moving into arctic environments and deep-water areas for oil production. In these regions of lower temperatures, wax deposits begin to form when the temperature in the wellbore falls below wax appearance temperature (WAT). This condition leads to reduced production rates and larger pressure drops. Wax problems in production wells are very costly due to production down time for removal of wax. Therefore, it is necessary to develop a solution to wax deposition. In order to develop a solution to wax deposition, it is essential to characterize the crude oil and study phase behavior properties. The main objective of this project was to characterize Alaskan North Slope crude oil and study the phase behavior, which was further used to develop a dynamic wax deposition model. This report summarizes the results of the various experimental studies. The subtasks completed during this study include measurement of density, molecular weight, viscosity, pour point, wax appearance temperature, wax content, rate of wax deposition using cold finger, compositional characterization of crude oil and wax obtained from wax content, gas-oil ratio, and phase behavior experiments including constant composition expansion and differential liberation. Also, included in this report is the development of a thermodynamic model to predict wax precipitation. From the experimental study of wax appearance temperature, it was found that wax can start to precipitate at temperatures as high as 40.6 C. The WAT obtained from cross-polar microscopy and viscometry was compared, and it was discovered that WAT from viscometry is overestimated. From the pour point experiment it was found that crude oil can cease to flow at a temperature of 12 C. From the experimental results of wax content, it is evident that the wax content in Alaskan North Slope crude oil can be as high as 28.57%. The highest gas-oil ratio for a live oil sample was observed to be 619.26 SCF/STB. The bubblepoint pressure for live oil samples varied between 1600 psi and 2100 psi. Wax precipitation is one of the most important phenomena in wax deposition and, hence, needs to be modeled. There are various models present in the literature. Won's model, which considers the wax phase as a non-ideal solution, and Pedersen's model, which considers the wax phase as an ideal solution, were compared. Comparison indicated that Pedersen's model gives better results, but the assumption of wax phase as an ideal solution is not realistic. Hence, Won's model was modified to consider different precipitation characteristics of the various constituents in the hydrocarbon fraction. The results obtained from the modified Won's model were compared with existing models, and it was found that predictions from the modified model are encouraging.

Download or read book Oil Pipeline Wax Disposition Inhibition Using Chemical Methods written by Norseri Mohd Mustaffa and published by . This book was released on 2010 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oil pipeline wax deposition is one of the major problems facing in the crude oil transportation flow line from the offshore to onshore through pipe. The problems occur because of the crude oil fluids temperature is decrease during the transportation process and cause the solidifying process occurs. The deposited wax is normally being removed using pigging process. In the present work, chemical method is introduced as an alternative solution for the wax deposition problems in pipelines. This method used CaCl2.2H2O and NaOCl as the inhibitor. The waxes is initially drowned in the NaOCl solutions to soften the waxes and remove the water content inside the sample; waxes. While drawn the sample, the solution with the waxes is stir to get the condition flowing through the pipeline. Then with fixed molarity of the CaCl2.2H2O solution, it is added to the NaOCl solution which has being reacted with the waxes samples. After a range of period; 24 hours, the result obtained is observed and recorded. This experiment is then repeated with different volume of NaOCl, using heat to study about the heat effect and also using acid to remove the waxes. The experimental results showed that with volume of 50ml NaOCl and 0.0071 M of CaCl2.2H2O, the waxes can break into small pieces and no weight loss to the wall like using 30 ml of NaOCl solutions with 70% weight loss from the initial sample weight. While using the heat, the waxes can be removes in 120s and gets 50% efficiencies for only 30 ml volume of NaOCl. This reaction has being tested gradually to ensure its ability to remove wax from the pipeline. The removal process has being removed using the chemical reactions between CaCl2.2H2O and NaOCl. The reaction of the chemicals and waxes was done in lab scale and the progress has being look properly in schedule time to ensure it properly removed. Inhibition of waxes using chemicals method finally founds it solutions which is means by reaction between Sodium Hypochlorite with Calcium Chloride Dihidrates together with bleaching theory, the problems can be eliminated and this kind of technique is more effectual based on its capability to recycle the chemical used back and need few periods to complete each reactions.
