In water-lubricated pipeline transportation of heavy oil and bitumen, a thin oil film typically coats the pipe wall. A detailed study of the hydrodynamic effects of this fouling layer is critical to the design and operation of oil-water pip...
Evaluation of numerical schemes for capturing shock waves in modeling proppant transport in fractures [0.03%]

In petroleum engineering, the transport phenomenon of proppants in a fracture caused by hydraulic fracturing is captured by hyperbolic partial differential equations (PDEs). The solution of this kind of PDEs may encounter smooth transitions...

In-depth understanding of interactions between crude oil and CO2 provides insight into the CO2-based enhanced oil recovery (EOR) process design and simulation. When CO2 contacts crude oil, the dissolution process takes place. This phenomeno...

The main objective of this work is to predict the mixing of two different miscible oils in a very long channel. The background to this problem relates to the mixing of heavy and light oil in a pipeline. As a first step, a 2D channel with an...
Natural resource dependence, public education investment, and human capital accumulation [0.03%]

This paper examines the relationships between natural resource dependence, public education investment, and human capital accumulation. It addresses why the "blessing" of abundant natural resources often turns into a "curse" in many countri...

The most prominent aspect of multiphase flow is the variation in the physical distribution of the phases in the flow conduit known as the flow pattern. Several different flow patterns can exist under different flow conditions which have sig...
Thermo-sensitive polymer nanospheres as a smart plugging agent for shale gas drilling operations [0.03%]

Emulsifier-free poly(methyl methacrylate-styrene) [P(MMA-St)] nanospheres with an average particle size of 100 nm were synthesized in an isopropyl alcohol-water medium by a solvothermal method. Then, through radical graft copolymerization o...
Zoeppritz-based AVO inversion using an improved Markov chain Monte Carlo method [0.03%]
基于Zoeppritz理论的改进型马尔可夫链蒙特卡罗逆AVO算法

Xin-Peng Pan et al.
The conventional Markov chain Monte Carlo (MCMC) method is limited to the selected shape and size of proposal distribution and is not easy to start when the initial proposal distribution is far away from the target distribution. To overcome...
Regularized least-squares migration of simultaneous-source seismic data with adaptive singular spectrum analysis [0.03%]
自适应奇异光谱分析的同时源地震数据正则化最小二乘逆时偏移迁移方法

Chuang Li et al.
Simultaneous-source acquisition has been recognized as an economic and efficient acquisition method, but the direct imaging of the simultaneous-source data produces migration artifacts because of the interference of adjacent sources. To ove...
