Wax Deposition Profile Estimation in Production Pipeline Review
Abstract: Wax deposition has been a major challenge in flow assurance of paraffinic crude oils. A major problem occurs because of a decrease in the bulk oil flowing and pipe wall temperatures. Wax deposits form when the temperature of the produced fluid falls below the wax appearance temperature or the cloud point temperature. Problems like pipeline plugging, increased pumping pressure and reduction in production rates are very common. Sophisticated mechanical and …

Determination of Possible Point of Wax Depositionalong Flowlines in the Niger Delta
Abstract: The focus of this study is to determine the possible point of wax deposition along an oil flowline in Niger delta. This research commenced with field studies to ascertain the flowline profile. The temperature profile along the flowline was determined using infra-red thermometer. Crude oil sample was taken from wellhead and laboratory analysis was carried out on the crude sample to determine the wax appearance temperature (WAT) of crude and …

Emerging Technologies to Control Wax Deposition in the Oilfields: An Overview
Abstract: Wax deposition on the well bore, production tubing, flow lines and pipelines reduces the production or flow capacity and increases the cost for the production and transportation of waxy crude oils in the oilfields. The different conventional methods for the control of wax deposition problems are mechanical, chemical, electrical, thermal and combination of others. But, there is no single solution to this problem that can be applied to all the …

Establishment of Wax Deposition Index from Saturates, Aromatics, Resins, Asphaltenes Analysis
Abstract: Saturates, aromatics, resins, asphaltenes (SARA) analysis is one method of characterizing crude oils. It is versatile because it can apply to many components of the crude oil. SARA analysis furnishes one with the composition of any crude and ultimately gives an idea of the potential of the crude oil to precipitate and deposit wax. This analysis method usually breaks crude oil down into four components (saturates, aromatics, resins and asphaltenes) …

Study on Effect of Insulation Design on Thermal-Hydraulic Analysis: An Important Aspect in Subsea Pipeline Designing
Abstract: The most imperative and challenging operational hazards for oil and gas pipelines are the risks associated with the transportation of fluids. When water, oil and gas flow simultaneously inside the pipeline, there are quite high chances that, water and hydrocarbon fluids can form and deposit hydrate such as wax and asphaltene on the inner surfaces of the pipeline and gradually blocking it. In this paper we explore and compare the …

Well Integrity and Reservoir Behavior under Sudden Field Shutdowns During Armed Conflicts: A Comprehensive Technical Review
Abstract: In the oil and gas industry, the sudden and unplanned cessation of operations resulting from armed conflicts or pandemics typically poses complex and multifaceted technical challenges to both well integrity and reservoir behavior. Minimal or no opportunity for proper pre-shutdown preservation procedures in unplanned shutdowns, unlike planned shutdowns that follow established operational protocols. The mechanisms and consequences of well integrity degradation and reservoir performance alteration under such conditions are synthesized …

Comparative Analysis of 3D-Printed and Molded Shape-Stabilized Phase Change Composites
Abstract: Thermal energy storage (TES) has become essential for efficiently storing and utilizing thermal energy across applications like industrial heating, power plants, batteries, medical devices, food preservation, and aerospace technology. Because of their high energy density, affordability, and environmental friendliness, phase change materials, or PCMs, are employed extensively. However, challenges like poor thermal conductivity and leakage limit their performance. To address these issues, 3D printing has emerged as a powerful tool …

Experimental Investigation and Surface Morphology Study on Areca Fiber Composite Material
Abstract: Composites manufactured from areca fibers had their characteristics assessed in recent research. Shape and size were determined by cutting the stem. It takes six months to dry the fibers once they are taken from the tree stem. Because pectin, cellulose, hemicellulose, and lignin make up the bulk of it. It has great regeneration capacity and is a resource material made of wood fibers. The untreated and chemically treated fibers are …

Study of Physical and Chemical Properties of Heavy Waxy Crude Oil from Cambay Basin Using Rheometer and Cross-Polar Microscope
Abstract: Production of heavy crude is quite difficult as the pressure drops from reservoir to production facility are quite large. This often leads to the precipitation and deposition of common organic solids (paraffin). These solids may deposit on surfaces, collect in low-energy regions or increase the effective viscosity of the flowing fluid. The net effect is an increase in pressure drop for a given rate through reduction in flowing area or …
