Sedimentary facies and model of gentle slope shallow-water braided river delta in the Jurassic Sangonghe Formation, Yanqi Basin, China

The Jurassic Sangonghe Formation of Yanqi basin develops a set of shallow braided river delta deposits, and it is of great significance for the exploration and development of Baolang oilfield to study its sedimentary characteristics. Based on the core data and wire-line log data in the study area with a highly dense well pattern, this work aims to provide the sedimentary features...

A New Mathematical Model For Heat Radius of Cyclic Superheated Steam Stimulation with Horizontal Wellbore

When superheated steam flows along the horizontal wellbore, it may change to saturated steam at some point of the wellbore. In this paper, to accurately predict the heat radius of cyclic superheated steam stimulation with horizontal wellbore, the distribution of thermophysical properties of superheated steam along the horizontal wellbore is considered. The heating process is...

Distribution of remaining oil based on fine 3-D geological modelling and numerical reservoir simulation: a case of the northern block in Xingshugang Oilfield, China

As the Xingshugang Oilfield is in the late stage of development, a conventional geological model could not meet the needs of further enhancing oil recovery, and the establishment of a fine 3-D geological model, namely the 3-D reservoir architecture model, is urgently required. The 3-D reservoir architecture model has a strong advantage in the detailed characterization of the...

Biological Computation Indexes of Brain Oscillations in Unattended Facial Expression Processing Based on Event-Related Synchronization/Desynchronization

Estimation of human emotions from Electroencephalogram (EEG) signals plays a vital role in affective Brain Computer Interface (BCI). The present study investigated the different event-related synchronization (ERS) and event-related desynchronization (ERD) of typical brain oscillations in processing Facial Expressions under nonattentional condition. The results show that the lower...

Combination and distribution of reservoir space in complex carbonate rocks

This paper discusses the reservoir space in carbonate rocks in terms of types, combination features, distribution regularity, and controlling factors, based on core observations and tests of the North Truva Oilfield, Caspian Basin. According to the reservoir space combinations, carbonate reservoirs can be divided into four types, i.e., pore, fracture–pore, pore–cavity–fracture...

Effects of Visual Working Memory on Brain Information Processing of Irrelevant Auditory Stimuli

Selective attention has traditionally been viewed as a sensory processing modulator that promotes cognitive processing efficiency by favoring relevant stimuli while inhibiting irrelevant stimuli. However, the cross-modal processing of irrelevant information during working memory (WM) has been rarely investigated. In this study, the modulation of irrelevant auditory information by...

Influence of meandering river sandstone architecture on waterflooding mechanisms: a case study of the M-I layer in the Kumkol Oilfield, Kazakhstan

In order to explore the influence of sandstone architecture on waterflooding mechanisms using the architecture method, and taking as an example the M-I layer of the Kumkol oilfield in the South Turgay Basin, Kazakhstan, we portrayed the architecture features of different types of sandstones and quantitatively characterized heterogeneities in a single sand body in meandering river...

Temperature distribution of fluids in a two-section two-phase closed thermosyphon wellbore

Compared with a conventional single section two-phase closed thermosyphon (TPCT) wellbore, a two-section TPCT wellbore has better heat transfer performance, which may improve the temperature distribution of fluid in wellbores, increase the temperature of fluid in wellheads and even more effectively reduce the failure rate of conventional TPCT wellbores. Heat transfer performance...

Visual mismatch negativity elicited by facial expressions: new evidence from the equiprobable paradigm

Background Converging evidence revealed that facial expressions are processed automatically. Recently, there is evidence that facial expressions might elicit the visual mismatch negativity (MMN), expression MMN (EMMN), reflecting that facial expression could be processed under non-attentional condition. In the present study, using a cross modality task we attempted to investigate...

Own- and other-race categorization of faces by race, gender, and age

We investigated how visual experience with faces of a particular race affects subordinate group-level categorizations in Chinese and Israeli participants living in the respective countries. Categorization of faces by race, gender, and age was examined within subjects with participants who had only minimal experience with the other-race faces. As would be predicted by the...

Hyperthermia-Induced Disruption of Functional Connectivity in the Human Brain Network

Background Passive hyperthermia is a potential risk factor to human cognitive performance and work behavior in many extreme work environments. Previous studies have demonstrated significant effects of passive hyperthermia on human cognitive performance and work behavior. However, there is a lack of a clear understanding of the exact affected brain regions and inter-regional...
