We present a set of interactive 3D visualizations, designed to explore oil/gas reservoir simulation post-processing models. With these visualizations we aim to provide reservoir engineers with better access to the data within their 3D models. We provide techniques for exploring existing oil well trajectories, and for planning future wells, to assist in decision making. Our approach focuses on d...

The changes occurring during aging of reservoir core samples in crude oil, which aims to restore the reservoir wettability, are complex. The dynamic mechanisms involved are still not entirely clear. Understanding the dynamics of wettability restoration in the laboratory will improve our ability to reproduce reservoir conditions before performing core tests and help to ensure that laboratory dat...

It is often presumed that fine-scale surface pores and roughness in reservoir rock remain water-wet. To test this assumption, deposition tendency of asphaltenes and resins during crude oil aging of brine-filled pores was investigated. Model frameworks of water-wet silica with sub-micron pores were synthesized as planar films of thickness 5 μm. These pore networks were conditioned in brine, subm...

We are developing a finite element program for oil and gas reservoir simulation based on Biot’s poroelastic theory, where a simultaneous solution is sought for both the pore pressure and strain in the solid phase. Several 2-D and 3-D cases are presented, which are compared with analytical solutions for verification of this approach. We have also applied this method to simulate surface subsidenc...

Gas injection into carbonate formations is one of the most important activities to protect oil reserves that can guarantee a steady production. On-time injection of enough gas can result in the recovery of billions barrels of oil. In addition, it can preserve a huge amount of gas for the next generations. If the reservoir depth is shallow, or the reservoir fluid has a little amount of intermedi...

water injection is an enhanced oil recovery method which is applied for number of reservoirs especially in the offshore fields around the world. sea-water injection process is usually associated with important concerns affecting the efficiency, safety, and economy of the operation like formation damage, mineral scaling, early breakthrough and corrosion. incompatibility between injected and form...

Sarvak Formation as the oil reservoir with the most hydrocarbon potential in Yaran oil field is of special importance. The present research was conducted to study the reservoir parameters of this Formation. For this purpose, petro-physical crude data was first prepared and using the Geolog6.7 software, a petro physical plot was drawn. Afterward, petro-physical properties of reservoir were done ...

The paper briefly describes the effects of diffusion and dispersion and other effects present during the oil displacement processes with miscible fluids, i.e. solvents. Recovery of oil is significantly improved during the application of such processes, but at the same time accompanied with decrease or even total loss of solvent slug. When designing such processes, particular attention should be...

Oil and gas reservoir flow simulation models are computational models that converge reservoir data collected from several sources into a single entity. They are used by reservoir engineers to forecast reservoir behaviour, a fundamental activity for better understanding of the underground reserves; they are also analyzed and discussed by a team of experts in related fields, ultimately attempting...

CO2 EOR and Storage in Oil Reservoirs — CO2 injection into tertiary oil reservoirs has been widely accepted as an effective technique for enhanced oil recovery (EOR), and has been used by the oil industry for over 40 years. Concerns over greenhouse gas emissions are leading to the investigation and realisation of its potential as a carbon storage method in recent years. With the right reservoir...
