Asphaltene Deposition: Development and Application of Polymeric Asphaltene Dispersants
SPE Annual Technical Conference and Exhibition, 1991ABSTRACT Asphaltene deposition has a significant detrimental effect on oilfield production. The key to effective treatment of asphaltene deposition is recognition of the problem. Asphaltenes can be identified and quantified using laboratory methods.

Modeling of Asphaltene Deposition Kinetics
Energy & Fuels, 2020Any change in the crude oil system equilibrium causes asphaltene precipitation, aggregation, and finally deposition on rock or pipe surfaces.

Introduction Production of heavy oils and paraffinic crude reserves often results in the deposition of organic solids, typically waxes or asphaltenes. The organic deposits can reduce the productivity of the reservoir as well as foul piping and surface equipment.

Asphaltene Deposition in Production Facilities
SPE Production Engineering, 1990Summary Asphaltene deposition in the tubing and production facilities caused operational problems in the Ula reservoir. Laboratory and field studies were carried out to determine the point of asphaltene precipitation. Laboratory observations were made on the regimes of deposition as a function of decreasing pressure down to and below the

Asphaltene Deposition Forecasting Methods
Advanced Materials Research, 2012Asphaltene deposition problems occurred in many oil fields in worldwide, which maybe block up wellbore, damage the permeability of reservoir and decline oil productivity. There are many factors to result asphalthene deposition problems, which contain crude component, pressure, temperature and so on.

On the Development of an Asphaltene Deposition Simulator
Energy & Fuels, 2010The potential problem of asphaltene deposition during oil production has motivated the development of several experimental techniques and theoretical models to understand and predict asphaltene behavior. Although important progress has been made in this area, prediction of the rate of asphaltene deposition remains an unsolved problem.

A Fundamental Study of Asphaltene Deposition
Energy & Fuels, 2013Asphaltenes are a solubility class of petroleum crude oil that can destabilize and deposit in both upstream and downstream processes. In this study, asphaltene deposits were generated in metal capillaries by heptane addition to crude oils, and it was found that deposition is caused by submicrometer asphaltene aggregates.

Asphaltene Deposition in Capillary Flow
SPE Annual Technical Conference and Exhibition, 2013Abstract Asphaltene precipitation and deposition may cause severe problems during production, transportation and processing of crude oil, hence affecting efficiency and cost of production in both upstream and downstream operations. During crude oil production they can deposit in rock reservoir pores, thus leading to possible blocking and

Controlling Asphaltene Deposition in Ageing Wells
SPE International Conference on Oilfield Chemistry, 2023Abstract ADNOC Onshore produces asphaltene-unstable crudes subject to severe wellbore deposition, which is exacerbated by miscible WAG injection. In one of the oilfields, commissioned in 1973 and producing approximately 400,000 BPD from 4 key reservoirs a cluster of approximately 20 wells experienced severe asphaltene deposition.

Solubility Characterization of Asphaltene Deposits
SPE International Symposium on Oilfield Chemistry, 2015Abstract In view of the great impact of asphaltene deposition in the petroleum industry, it is of paramount importance to estimate the tendency of crude oils and petroleum products towards precipitation as well as the potential amount of material that can precipitate. These are important parameters to consider in designing and monitoring
