  • Wax problems in production - OnePetro
    Many crudes contain dissolved waxes that can precipitate and deposit under the appropriate environmental conditions These can build up in production equipment and pipelines, potentially restricting flow (reducing volume produced) and creating other problems This page discusses how to anticipate, prevent, and remediate wax problems in production
  • Paraffin Inhibitors and Paraffin Dissolvers | SLB
    Paraffin inhibitors We offer a wide variety of paraffin inhibitors to meet your specific needs: paraffin deposition inhibitors—high-molecular-weight polymers that interact with paraffins in crude to modify or inhibit wax crystal formation, shape, and size, so that surface adhesion is eliminated pour-point depressants—polymers with n -alkyl chains that similarly impede wax crystal formation
  • Paraffin Wax Production Process: Step-by-Step Guide - PetroNaft
    Learn the Paraffin Wax Production Process step by step—from distillation and dewaxing to hydrofinishing, QC tests, and buying specs
  • Prediction and Simulation of Wax Deposition in Oil and Gas Wells
    It is therefore important to predict the deposition of waxe during oil and gas production In order to study the deposition pattern of wax in the wellbore, the wellbore flow and heat transfer processes were analysed, and a method for predicting the wellbore flow, temperature, and pressure was developed and coupled to the pressure and temperature
  • Ultimate Guide to Wax Management in Oil Production
    Wax buildup in oil production can cause major flow issues, increase costs, and even lead to complete system blockages Here’s what you need to know: What Causes Wax Issues: Wax forms when crude oil cools below its Wax Appearance Temperature (WAT), leading to deposits in pipelines and equipment This is common in colder environments or during pressure drops Why It Matters: Wax buildup
  • Wax Management Strategy Part 3: Design, Development Maintenance
    In the previous parts of this series, it was established that wax deposition is an issue that arises whenever an oil composition containing appreciable wax content encounters flow, temperature, and pressure that are conducive for solids formation The effective development of wax management strategies during Front End Engineering Design (FEED) can serve to mitigate or perhaps even prevent the
  • Development of a New Model for the Formation of Wax Deposits . . . - MDPI
    Wax deposits related to flow assurance are a costly problem in oil production in many fields around the world Modeling of this process is the main tool for creating and optimizing methods to deal with this problem This paper considers a new empirical model for the formation of these deposits, based on the results of an array of laboratory studies, theoretical data and technological
  • Preventing and removing wax deposition inside vertical wells . . . - Springer
    The temperature loss induces crystallization of the wax and the subsequent plugging of the well In this case, wax deposition leads to the decrease of well flow rates and eventually causes total blockage This paper sums up the main technologies applied to prevent or remediate the wax deposition formed inside the wells
  • Wax Production Essentials in Petroleum Refining
    Wax Production Processes The production of wax involves several key steps, from refining crude oil to the final purification of wax products Description of the Refining Process for Wax Production Crude oil is a complex mixture of hydrocarbons, and refining it involves separating these components based on their boiling points and other properties
  • paraffin wax production + paraffin wax analysis | RAHA Paraffin Co
    Paraffin Wax Production In equilibrium condition Paraffin is completely dissolved in crude oil Make Changes in temperature and pressure leads to disturb this equilibrium, which might result in paraffin precipitation and crystallization Basically, the solubility of the paraffin wax is very sensitive to temperature changes For example, if the temperature of surface of pipe is below the oil
