Application of discrete fracture network modeling technology in mudstone fractured reservoir in Daqing oil region

, 2018
The mudstone fractured oil and gas reservoir is a kind of special unconventional reservoirs and its hydrocarbon mainly exists in fractures. This kind of reservoirs has industrial exploitation value due to the large reserves, but the complex geological ...

Experiments on nitrogen assisted gravity drainage in fractured-vuggy reservoirs

Petroleum Exploration and Development, 2019
Visual models of fractured-vuggy reservoirs were designed and manufactured to conduct experiments of nitrogen assisted gravity drainage (NAGD). The impacts of flooding pattern, gas injection rate, well type, and displacement direction (vertical or ...

Scalable Fabrication of Chemically Stabilized Gelatin Hydrogel Fibers by Thermal Drawing

Advanced Materials Interfaces, EarlyView.
Scalable processing of hydrogel fibers remains a major challenge. By coupling thermal drawing with Maillard chemistry, a transient viscous‐flow window is created that enables continuous fabrication of microstructured gelatin fibers tens of meters long, while continued in situ crosslinking during drawing stabilizes the fibers for physiological ...

Reservoir characterization and potential of the old red sandstone around the inner moray firth, NE Scotland [PDF]

, 1993
Old Red Sandstone deposition in North East Scotland occurred during Devonian times within the Orcadian Basin, a northeast-southwest elongated structure. The basin formed in an extensional tectonic regime that resulted from gravitational collapse of over ...

Culinary Chemistry as a Platform for Interfacial Materials Design

Advanced Materials Interfaces, EarlyView.
Culinary processes control interfaces through heating, shear, gelation, and molecular transport. This Review connects selected gastronomic examples with food‐derived nanomaterials, plasmonic sensing, anthocyanin photovoltaics, and intelligent packaging. Original agar‐based plasmonic films illustrate the proposed translation.

Three-dimensional and two-phase numerical simulation of fractured dry gas reservoirs

Journal of Petroleum Exploration and Production Technology, 2018
A significant percentage of hydrocarbon reservoirs around the world is fractured. Moreover, the major part of gas reservoirs in Iran is also fractured type, so the existence of an in-house software is necessary. In this study, an efficient, user-friendly,

Experimental Studies of Immiscible High-Nitrogen Natural Gas WAG Injection Efficiency in Mixed-Wet Carbonate Reservoir

Energies, 2020
Crucial oil reservoirs are located in naturally fractured carbonate formations and are currently reaching a mature phase of production. Hence, a cost-effective enhanced oil recovery (EOR) method is needed to achieve a satisfactory recovery factor.

High Throughput Aerosol Jet Printing to Operationalize High Aspect Ratio Patterning

Advanced Materials Technologies, EarlyView.
High‐throughput aerosol jet printing poses distinct limiting mechanisms to the printing process. These include rapidly changing ink chemistries, atomization instabilities, and liquid‐phase spreading. The combination of in‐line heating, process monitoring, and traditional optimization procedures enables rapid printing of high‐aspect‐ratio structures ...

Significant effect of compositional grading on SAGD performance in a fractured carbonate heavy oil reservoir

Journal of Petroleum Exploration and Production Technology, 2019
In reservoir simulation, the fluid composition is usually assumed uniform for the whole reservoir, while in many reservoirs, oil and gas composition changes with depth. This phenomenon which is known as compositional grading could be significant in heavy
