...Mehdi Izadi _ Heavy oils are characterized by high-density, high-viscosity, and high-heavy-fraction components. One of the more common characteristics of heavy oil reservoirs is a low primary recovery factor, which is mainly because of unfavorable mobility ratios between oil and water, negligible...

Introduction Because of its comprehensive nature, much of the complete paper is dedicated to a review of the characteristics of heavy oil reservoirs and their exploitation, including thermal and nonthermal methods and the literature dedicated...

... in an onshore field in Iraq using different bit designs and with a variety of downhole conditions. To improve the rate of penetration (ROP) in a significant manner, a radical shift in how drill bits are selected, as well as a closer look at bit characteristics, is needed. This work aims to combine analytical...

... distribution (PSD) characteristics (D10, fines content, and uniformity coefficient). PSD is critical data for traditional sand-control analysis, and multiple cores are used to represent the varying rock characteristics expected throughout a reservoir. The selection of sand control and the ultimate completion...

... of the near-wellbore fracture geometry or cluster or stage productivity through FO has proved to be more difficult. A new FO diagnostic method, distributed strain sensing based on Rayleigh frequency shift (DSS-RFS), provides insights about the characteristics of the near-wellbore-region (NWR) during...

... at various gas/liquid flow patterns and considering the phase distribution and interface distribution characteristics of different flow patterns. Introduction Hydrate blockage risk in transportation pipelines is one of the most important topics in the study of flow assurance. Large-scale natural gas...

The prevention of screen out is related to the different bridging characteristics of conventional- and pillar-fracturing slurries. The stable voids within the proppant pack...

This method of computing is very efficient in solving inverse problems where parameters affecting system characteristics are not completely known. Hydrocarbon reservoirs provide a classic case of a natural system...
