... for this interval ( Fig. 5 ). The lower block is identified between depths X302 m and X307 m. The GR responses in the upper block and lower block may indicate the presence of a repeat section. The responses of the other logs revealed that the mineral content of the shale has significant variations in the upper...

... 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...

... that approximately maps WAG injection parameters to cumulative recoveries. Architecture The network comprises an input layer, two hidden layers, and a specialized output layer to avoid overfitting issues even in the absence of sufficient variations in the dataset or limited number of samples. The input...

.... 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...

The historical...

...-2 will equal to 13.58%. This difference in the measured porosities can be attributed to the variation in the diagenetic overprints among the samples. The conventional and digital screening methods revealed three types of cuttings ( Figure 6 and 7 ): The shale cuttings obtained from interval...

... This CT textural analysis is important to consider together with porosity variations when selecting plugs from (single-mineralogy) reservoir core intervals. Missing this textural analysis in the sampling process may cause high permeability intervals to be unrepresented in the final set...

The challenge was to design a systematic approach for capturing PVT property variations, performing oil compositional variation modeling, and understanding PVT...

... 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...
