Wettability Challenges in Carbonate Reservoirs

open access: yes, 2010
Injection of water for pressure maintenance and waterflooding applications is becoming an increasingly important issue. Historically, the total suspended solids of the water were given more consideration rather than the total dissolved solids.

Chemical Maturation Controls Bioavailability of Fetuin‐A‐Mineral Complexes in Biomineralization

open access: yesAdvanced Functional Materials, EarlyView.
The role of Fetuin‐A‐mineral complexes in matrix mineralization is unclear. Here, Fetuin‐A‐mineral complexes were found to exist in functionally distinct states that determine mineral bioavailability: chemically labile calciprotein monomers directly mineralize collagen fibrils, while chemically matured primary calciprotein particles require cellular ...

Genesis and characteristics of the dolomite reservoirs in Middle Devonian Guanwushan Formation, Northwest Sichuan Basin, SW China

open access: yesPetroleum, 2020
A great breakthrough has been made on oil-gas exploration of the Middle Devonian Guanwushan Formation in Northwest Sichuan Basin. The further exploration shows that the dolomite reservoir is complicated with insufficient investigation.

Mimicking Silent Synapse Recruitment: A SiOx/Cu‐Pancake Memristive Device For Analog Neuromorphic Computing

open access: yesAdvanced Functional Materials, EarlyView.
Electroforming‐free TiN/SiOx/Cu/SiOx/TiN memristive devices exploit pancake‐like Cu nanoparticles embedded in a SiOx double layer to create a heterogeneous Schottky‐barrier landscape. Under bias, oxygen‐vacancy redistribution progressively lowers local barriers and recruits initially inactive Cu‐PC pathways into a parallel conduction ensemble, enabling

Application of new dating and temperature-measuring technologies in study of strike-slip fault-controlled reservoirs and hydrocarbon accumulation: A case study of Ordovician strata in non-foreland area of Tarim Basin, NW China

open access: yesPetroleum Exploration and Development
Focusing on the geochronological issues related to the matching relationship between the strike-slip fault activity and the stages of hydrocarbon generation, reservoir formation, and hydrocarbon accumulation, this study aims to quantitatively constrain ...

Spontaneous Helical Alignment of Smooth Muscle Cells to Form a Medial Layer for Engineered Microvasculature

open access: yesAdvanced Healthcare Materials, EarlyView.
Spontaneous helical alignment of smooth muscle cells is induced within resistance‐vessel‐sized channels patterned within a hydrogel. The extent of the cells’ orientation angle is dependent on the presence and composition of ECM proteins lining the channel wall and cell seeding density.

Gas kick during carbonate reservoirs drilling and its risk assessment

open access: yes, 2017
The gas kick characteristics during carbonate reservoir drilling were analyzed taking carbonate reservoirs in Shunnan area of Tazhong as an example, a quantitative evaluation method for gas kick risk was established, and then a case was simulated ...

Oil-Water-Rock Interactions and Their Implications for Waterand 1-Pentanol-Assisted Enhanced Oil Recovery in Carbonate Reservoirs [PDF]

open access: yes, 2021
Low-salinity waterflooding appears to be a cost-effective and environmentally friendly means to enhanced oil recovery in carbonate reservoirs. Wettability alteration has been identified as an important process during low salinity waterflooding.

Role of the injected water salinity and ion concentrations on the oil recovery in carbonate reservoirs

open access: yes, 2021
Low salinity water flooding (LSWF) was initially considered using water with a low concentration of dissolved salts and was later extended to include modifying the ionic content of injected brines.
