This paper introduces mathematical models with memory to present the complex rheological phenomena combining the in situ shear rate and bulk rheology with fluid memory. The models are solved numerically and the results compared with established experimental data available in the literature. The new models showed excellent agreement with experimental results for the region where most existing mo...

Oman is currently a particular “hot spot” for investment in a range of EOR techniques to produce heavy oil, but is much less visible in industry statistics than countries such as Canada and Venezuela. Other countries in the Middle East are encouraged by Oman’s success and, with the additional impetus of increasing oil prices, are becoming more active in heavy oil production. For example, Iran a...

One of the major challenges in petroleum industry is producing residual oil from underground. One of the major techniques for enhancing oil recovery (EOR) is using gas injection. However, gas has poor volumetric sweep efficiency, this is attributed to its high mobility which considers to be higher compared with oil and water mobility. Several techniques are proposed and applied for reducing gas...

X-ray microdiffiaction is a non-destructive technique that allows for depthresolved, strain measurements with sub-micron spatial resolution. These capabilities make this technique promising for understanding the mechanical properties of MicroElectroMechancial Systems (MEMS). This investigation examined the local strain induced by irradiating a polycrystalline diamond thin film with a dose of 2x...

Surface-active ionic liquids (SAILs) have multiplied the possibilities of surfactant enhanced oil recovery (EOR) methods. Among their multiple promising features, possibility functionalization and stability at harsh conditions should be highlighted for application. They been successfully applied to increase by improving crucial parameters such as: formulation stability, reduction water–oil inte...

Residual oil zones (ROZs) could present a new, potentially large and commercially viable resource for Australia provide an avenue geological storage of carbon dioxide (CO2) through CO2 enhanced recovery (CO2-EOR). These reservoirs, which can contain moderate amount residual resemble water-flooded fields, be associated with conventional fields (brownfields) or occur no main pay zone (greenfields...

The period in which hydrogen the intergalactic medium (IGM) is ionized, known as Epoch of Reionization (EoR) still poorly understood. timing and duration EoR expected to be governed by underlying astrophysics. Furthermore, most models reionization predict a correlation between density ionization field. Here we consider using mean dispersion measure (DM) high redshift Fast Radio Bursts (FRBs) pr...

The mobility profiles of gases used in enhanced oil recovery (EOR) have been thoroughly investigated through the coupling operations data mining oilfield and experimental analyses. Mobility as an EOR objective function has not previously applied to characterize potential reservoirs for selection application, even though it is a robust combinatorial that benefits from two petrophysical var...

Quasars at cosmic dawn provide powerful probes of the formation and growth earliest supermassive black holes (SMBHs) in Universe, their connections to galaxy structure formation, evolution intergalactic medium (IGM) epoch reionization (EoR). Hundreds quasars have been discovered first billion years history, with quasar redshift frontier extended z ∼ 7.6. Observations show following: ▪ The numbe...
