We present analytical solutions for capillary-controlled displacement in one dimension by use of fractional-flow theory. We show how to construct solutions with a spreadsheet that can be used for the analysis of experiments as well as matrix-block-scale recovery in field settings. The solutions can be understood as the capillary analog to the classical Buckley-Leverett solution (Buckley and Lev...

The relative permeability curve is an important basic data for the preparation and dynamic analysis of oilfield development ( adjustment ) schemes. Due to different types curves in water cut stages, there a large deviation prediction indexes ultra-high stage according early development. In order study change process, based on morphological characteristics 118 28 coring wells Xingbei area after ...

We analyze the effect that geometry of Effective Propped Volume (EPV) has on economic performance hydrofractured multistage shale gas wells. study sensitivity production to EPV’s and we compare it with other parameters whose relevance in is well known: porosity, kerogen content permeability induced Stimulated Recovery (SRV). To understand these sensitivities, develop a high-fidelity 3D numerica...

The pore-throat radius of the shale oil reservoir is extremely small, and it difficult to accurately obtain absolute permeability oil–water two-phase relative actual through conventional core experiments. However, these parameters are very important for numerical simulation. In this paper, a method characterizing flow based on pore network model that considers differential pressure diffusion pr...

CO2-Plume Geothermal (CPG) power plants can produce heat and/or electric power. One of the most important parameters for design a CPG system is CO2 mass flowrate. Firstly, flowrate determines generated. Secondly, has significant effect on fluid pressure drawdown in geologic reservoir at production well inlet. This because it lead to water flow towards and into borehole. Thirdly, directly affect...
