STUDYING PRESSURE VARIATION IN A FRACTURED CARBONATE RESERVOIR PRODUCING UNDER STEAM FLOODING EOR WITH MULTIPLE FRACTURE MATRIX ARRANGEMENTS

Rudarsko-geološko-naftni Zbornik
The viscous oil reserves present around the world are estimated to be 2 trillion barrels, but to date, the lack of suitable technology for production causes these reserves present in complex reservoirs to negligibly contribute to world daily production ...

Remaining Oil Distribution and Development Strategy for Offshore Unconsolidated Sandstone Reservoir at Ultrahigh Water-Cut Stage

Geofluids, 2022
Due to the influence of long-term waterflooding, the reservoir physical properties and percolation characteristics tend to change greatly in offshore unconsolidated sandstone reservoirs at ultrahigh water-cut stage, which can affect the remaining oil ...

A Numerical Multistage Fractured Horizontal Well Model Concerning Hilly-Terrain Well Trajectory in Shale Reservoirs with Natural Fractures

Energies, 2022
Multistage hydraulic fracturing is one of the most prevalent approaches for shale reservoir development. Due to the complexity of constructing reservoir environments for experiments, numerical simulation is a vital method to study flow behavior under ...

INFLUENCE OF LOW PERMEABILITY BARRIER ON HOT WATER FLOODING PERFORMANCE – A NUMERICAL INVESTIGATION

Rudarsko-geološko-naftni Zbornik
The existence of a low permeability barrier acts as a geological discontinuity in oil reservoirs. The presence of such discontinuities could alter the flow of injected hot water in the formation and would significantly influence the hot water flooding ...

Impact of Exposure to Supercritical Carbon Dioxide on Reservoir Caprocks and Inter-Layers during Sequestration

Energies, 2022
The long-term exposure of rocks to supercritical carbon dioxide (scCO2) during sequestration creates structural and chemical changes. In turn, these lead to changes in the permeability of inter-layers and caprocks that can alter plume migration behaviour

Alternate Methods in Reservoir Simulation [PDF]

, 2001
As time progresses, more and more oil fields and reservoirs are reaching maturity; consequently, secondary and tertiary methods of oil recovery have become increasingly important in the petroleum industry. This significance has added to the industry's interest in using simulation as a tool for reservoir evaluation and management to minimize costs and ...

Simultaneous history-matching approach by use of reservoir-characterization and reservoir-simulation studies

, 2020
Reservoir characterization is the key to success in history matching and production forecasting. Thus, numerical simulation becomes a powerful tool to achieve a reliable model by quantifying the effect of uncertainties in field development and management

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.
