Abstract The raw materials of geopolymer come from industrial wastes, which have the advantages lower carbon emissions and less energy consumption compared with traditional cement products. However, it still has disadvantages low strength, easy cracking, production efficiency, limit its engineering application development. At present, development nanotechnology in field materials, is found that nanomaterials a good filling effect on composites, greatly improves integrity composites. It...
Summary Nanoscale porosity and permeability play important roles in the characterization of shale-gas reservoirs predicting shale-gas-production behavior. The gas adsorption stress effects are two crucial parameters that should be considered shale rocks. Although stress-dependent models have been introduced applied to calculate effective permeability, effect specified as pore volume (PV) occupied by adsorbate is not properly accounted. Generally, results significant reduction nanoscale...
Summary Petrographic work on thin sections from rock samples collected in tight gas sandstones of the western Canada sedimentary basin (WCSB) shows that are composed intergranular, microfracture and slot, isolated noneffective porosities. The petrographic observations these triple-porosity rocks have led to a petrophysical interpretation with use model. Tight reservoirs very complex heterogeneous systems been evaluated past mostly single-porosity models. We propose types can be represented...
An all-sapphire extrinsic Fabry-Perot interferometer (EFPI) optical fiber pressure sensor with ultra-wide range and high temperature resistance is proposed experimentally demonstrated. The fabricated by direct bonding three sapphire wafers, including the substrate, wafer a through hole, pressure-sensitive diaphragm. A femtosecond (fs) laser used to inscribe hole in center of roughen outer surface By using original polished surfaces wafers low roughness as reflective (FP) cavity, high-quality...
Abstract This paper presents our work on developing a platform for high performance reservoir simulations, which is developed to support the implementation of various simulators distributed-memory parallel systems. employs MPI (Message Passing Interface) communications and OpenMP shared-memory computation. It provides structured grids due its simplicity cell-centered data each grid cell. The has distributed matrix vector module map module. connects linear system modules. Commonly-used Krylov...
Abstract This paper presents an innovative workflow for characterization and reservoir simulation of the tight gas Nikanassin Group in Western Canada Sedimentary Basin. Petrographic studies show presence (1) intergranular, (2) microfracture + slot, (3) isolated (non effective) porosities. These porosities are handled with a mathematical triple porosity model improved petrophysical analysis Group. Determination pore throat apertures (rp35) facilitates facies mapping purposes. Numerical well...
Abstract Previous studies have examined the determinants of stock price crash risk. However, extant literature overlooks relationship between patent infringement litigation and Based on a dataset Chinese firm‐year observations for period 2007–2021, we fill gap by examining how affects risk underlying channels through which this effect occurs. We provide robust evidence that corporate increases its one‐year‐ahead crash. This unfavourable is more pronounced in firms were involved with...
Abstract Optimization of Steam Assisted Gravity Drainage (SAGD) remains a major concern in Surmont leases (an Athabasca oil sands deposit located northeastern Alberta, Canada) due to the extensive presence top gas and water zones over bitumen. Observation well data has detected pressure communication between SAGD steam chamber overlying thief zones. Maintaining is very difficult these zone interactions. Previous numerical simulations, laboratory experiments field production have demonstrated...
