... Abstract Different models have been proposed for deposition of asphaltene on reservoir rocks that due to complexity of asphaltene nature, most of them have not been productive. Here, a reliable model is proposed which despite of previous models, considers the change in asphaltene saturation...

... production and asphaltene deposition. This paper provides a methodology to choose the most feasible completion alternative to minimize sand production and asphaltene deposition in this field. Several analyses were made to determine possible causes and solutions of sanding and asphaltene deposition. Also...

... Abstract The deposition of asphaltene in porous media and their interaction with rock and fluids represent complex phenomena which needs to be investigated under dynamic flowing condition. It could occur by reducing mobility (λ=k/μ) in three probable mechanisms of asphaltene included damage...

... Impedance. Attribute seismic pseudo-Gamma Ray and Acoustic Impedance map were used to describe generally in lateral distribution reservoir. Log data and Biostratigraphy were integrated to decide depositional environment furthermore the correlation geology was built by sequence stratigraphy concepts...

...Conclusions The influences of gas flow rate, initial hydrogen sulfide concentration and reservoir rock permeability on sulfur deposition in the core samples from X sour gas reservoir are investigated from a laboratory and simulation perspective. Displacement experiments were conducted...

... Abstract Flow assurance has been one of the major considerations in deep water completion design, where undesired heat loss from production tubing contributes to the formation of gas hydrates and causes the deposition of paraffin and asphaltene materials. Traditionally, controlling annular heat...

... Abstract An accurate prediction of wax deposition profiles along a production line has significant impact on savings, pipeline design, flow assurance and operations of waxy crude production system in oil industry. Validation of wax deposition model by a field test is a necessary step to ensure...

... is that the surface of deposition was parallel to the basal horizon and as deposition proceeded upward became gradually parallel to the top. In this scenario, the individual sands thicken and thin proportionally to the thickness of the formation. The second one assumes that deposition parallel to the top horizon...

... ABSTRACT The origin and distribution of a sandstone reservoir for petroleum are controlled primarily by the processes by which the sand was deposited. Studies of modern environments of deposition and associated Holocene deposits provide a basis for understanding petroleum fields and predicting...
