... of the proposed AI model was reflected by the correlation coefficient (CC) ‘0.97’ between predicted and actual brittleness indices. The root mean squared ‘RMSE’ and average absolute percentage error ‘AAPE’ of the predicted brittleness were observed as 3.78 percent and 1.98 respectively for the ANN model. AAPE...

Experimental measurements with Slim Tube tests. Computer modeling based on equations of state for phase...

... in practice and is instead characterized by a transition time T n,tr . The parameters T ch , T n,tr are well correlated with the CDNC shape, as quantified by one or two fractions z α,β denoting the fraction of the NCDC between normalized saturations α and β . Late time recovery was modeled using...

... to the high viscosity or medium viscosity group. For cutting analysis, we thoroughly investigated solvent extracts from cuttings from the exploration and appraisal wells and correlated them with the oil viscosity from the corresponding PVT samples. When such a correlation is established, we can then apply...

Possible improvements were identified in dataset preparation and feature selection to get more robust models. artificial intelligence machine learning correlation metaparameter support vector machine evolutionary algorithm selection particle new well upstream oil...

... the petrophysical properties were randomly distributed with spatial correlation. We examined a wide range of geological realisations which mimic complex geological structures. Sandstone was simulated using a log-linear porosity-permeability relation with fairly good correlation. A carbonate reservoir from...

... are the objectives of history matching, within current implementation can have a variety of representations as Corey, LET, B-Splines and NURBS. For the purpose of analyzing the influence of correlations on the history matching results in this study, the interpretation process with assumed analytical correlations...

... and failed experiments, and standardize the dataset. Regularization was employed to eliminate features that didn't contribute to accurate prediction. Feature engineering was used to construct new features from our dataset. We began by measuring the correlations between features to better understand the data...

... Assume we have found three prospects in a frontier exploration play. Our experts have assessed the chance of success for drilling prospects α, β, and γ. In addition, we believe these prospects are correlated: once we drill any of them, we could use the information from the first well to update...

... Abstract Accurate calculation of adsorbed shale gas content is critical for gas reserve evaluation and development. However, gas adsorption and desorption experiments are expensive and time-consuming, while physics-based models and empirical correlations are unable to accurately capture...

... and applied a two-step methodology to improve upscaled coarse-scale results for these models. We then propose a consistent procedure to expand the fitted pseudo-functions to all the coarse models, providing an effective ensemble-level upscaling. The correlation between Koval factor and oil recovery...

Stratigraphic correlation with offset wells, using conventional LWD data supported by Image Log interpretation, allowed allocating resistivity boundaries in terms of stratigraphic surfaces...

... and D3 have a good positive correlation. The pore system studied mainly consists of organic pores and microfractures, with the percentage of micropores being 50.38%. TOC has a positive relationship with porosity and D3 due to the development of organic pores. D3 has a positive correlation with gas...

The second highest production is from Stage 10, but due to the shortening of the monitoring time, we do not have a ΔLO i . The delta PILF does have a positive change, but further correlation can not be made without...

We show that the real option methodology will identify the optimal time to start exploration drilling. We also demonstrate the effect of correlation...

It is based on a rock physics study to derive field specific correlations between mechanical properties and interpreted petrophysical quantities. The 3D MEMs built using this methodology yield robustness and consistency...
