A memristor is a two-terminal nanodevice that its properties attract a wide community of researchers from various domains such as physics, chemistry, electronics, computer and neuroscience. The simple structure for manufacturing, small scalability, nonvolatility and potential of using in low power platforms are outstanding characteristics of this emerging nanodevice. In this report, we review a...

Abstract The planning and developmental decisions succeeding the discovery of an unconventional oil gas field is utmost importance in attaining successful exploitation production from these tight reservoirs. development hydrocarbon reservoirs require requires adequate execution which could be challenging, due to sequence heterogeneous lithologies formations. In this study, we designed presented...

Abstract Foamed and energized fluids fracturing has been used in both conventional unconventional reservoirs, as they reduce the amount of water hence minimize deleterious impact on water-sensitive formations. They also aid flow back after treatment reservoirs where drawdown is limited. In this paper, most important foam properties are presented, addition, when to use how choose best energizing...

Understanding the pore networks of unconventional tight reservoirs such as tight sandstones and shales is crucial for extracting oil/gas from such reservoirs. Mercury injection capillary pressure (MICP) and N2 gas adsorption (N2GA) are performed to evaluate pore structure of Chang-7 tight sandstone. Thin section observation, scanning electron microscope, grain size analysis, mineral composition...

Current geological extraction theory and techniques are very limited to adequately characterize the unconventional oil-gas reservoirs because of the considerable complexity of the geological structures. Optical measurement has the advantages of non-interference with the earth magnetic fields, and is often useful in detecting various physical properties. One key parameter that can be detected us...

Unconventional shale reservoirs as the result of extremely low matrix permeability, higher potential gas productivity requires not only sufficient gas-in-place, but also a high concentration of brittle minerals (silica and/or carbonate) that is amenable to hydraulic fracturing. Shale lithofacies is primarily defined by mineral composition and organic matter richness, and its representation as a...

The largest marine carbonate oilfield and gas condensate field in China have been found the Ordovician limestones central Tarim Basin. They are defined as large “layered” reef-shoal karstic reservoirs. However, low and/or unstable oil/gas production has a big challenge for effective exploitation ultra-deep (>6000 m) reservoirs more than 20 years. Together with static dynamic reservoir data, ...

Low to ultralow permeability formations require "special" treatments/stimulation to make them produce economical quantities of hydrocarbon and at the moment, multi-stage hydraulic fracturing (MSHF or MHF) is the most commonly used stimulation method for enhancing the exploitation of these reservoirs. Recently, the slot-drill (SD) completion technique was proposed as an alternative treatment met...

This paper presents a review of the basic, model-independent differences between the pre-big bang scenario, arising naturally in a string cosmology context, and the standard inflationary scenario. We use an unconventional approach in which the introduction of technical details is avoided as much as possible, trying to focus the reader’s attention on the main conceptual aspects of both scenarios...
