... a non-faulted and non-fractured reservoir can exhibit pressure cluster differentiation. Numerical experiments are performed using hypothetical models to study the impact that stepwise and continuous permeability variations, the permeability ratio, duration of shut-in, and flowrate all have...

... Abstract A challenging step in reservoir modeling is capturing fluid composition variation. This is a complex task as fluid samples taken from wells in different areas of the reservoir usually have large areal and vertical compositional variation. Modeling representative composition variation...

... the presence of the repeat section. The minerology differences between the original and repeat sections have highlighted the facies variations in the Longmaxi Shale. This is also the reason why the MTC could occur in this area. Based on the calibrations of well data, the geometry and architecture of the MTC...

.... An accurate heat transfer characterization of the well has been implemented to predict the temperature changes along the wellbore during time, as well as the thermal effect due to pressure variations (Joule-Thompson effect). The effectiveness of the implemented algorithm has been proven by its application...

... plugs were selected in a full-diameter heterogeneous core from a carbonate reservoir in the Middle East. The sample selection was based on statistical distribution of porosity and CT-textures in the core. The porosity and textural variations were determined along the core length at 0.5 mm resolution...

... reservoir with multiple producing zones. A variation in PVT properties was evident from laboratory tests conducted on the collected fluid samples. The challenge was to design a systematic approach for capturing PVT property variations, performing oil compositional variation modeling, and understanding PVT...

... seismic data variation prediction interpretation geological model dynamic model Introduction Seismic porosity prediction can improve reservoir characterization by providing information on the spatial variation of the reservoir away from existing well control. The integration of well-log...

... plugs were selected in a heterogeneous reservoir interval based on statistical distribution of litho-types in the core. The litho-types were described by porosity and mineralogy variations along the core length using advanced dual energy XCT imaging. Plug-scale rock types were defined on the basis...
