... is selected as the predictive model for CO 2 injectivity impairment during CO 2 sequestration in a saline aquifer. The results revealed that both SVR and GA-SVR are able to capture the precise correlation between measured and predicted data. However, the GA-SVR model slightly outperformed the SVR model...

... be reported in the mud logs, composite logs and end of wells reports for source rock stratigraphic interval. A study based on tectono-stratigraphy, regional basin analysis, petroleum system chart, available well data and well log correlations may helpful to understand the major tectonic events, stacking...

... in the stratigraphic correlation resolution, particularly in the deeper/older sections, allowing correlations to be made across different fault block segments, a near-impossible task with conventional methods and workflows. A quick look of this from three wells (SF3, SF-39 and SF-28), overlain with seismic...

..., some statistical error analyses, namely, the average absolute percentage relative error (AAPRE), and the correlation coefficient (R) were performed to present the robustness and accuracy of the proposed model. The findings from the trend analysis showed the sound relationships between the inputs...

... formulation to quantify the communication strength coefficient for an injector – producer well pair was derived from the Spearman's rank correlation coefficient. The calculation is controlled with injection/production rates pattern for each well pair. Subsequently, multivariate parametric regression...

.... These variety sets of data will help to populate the geological features of the reservoir in bulk and each individual layer in depths. The process includes developing the correlation between pore throat size and pore throat connectivity networking. Defined from core plug pore throat pattern and tie to well...

... Abstract Seismic-well tie is a crucial process to correlate subsurface information from well logs and acquired seismic data. Traditionally, a manual seismic-well tie is conducted based on the interpreter's visual pattern recognition, which is subjective, time-consuming, and may lead...

... Abstract Correlations are prevalent in the geotechnical engineering practice. This paper presents a practical machine learning approach for establishing improved geotechnical correlations. In the realm of machine learning, multiple input variables of significance can be readily and coherently...

Standardized correlation guidelines between operational strain and service sourness is developed for a typical carbon steel pipeline installed in shallow water handing sour fluid (low pH). The outcome of ECA study is mainly dependent...

.... An extensive research effort has been spent over the past 60 years to develop robust correlations for the use of Venturi flowmeters to correct the over-reading due to the unexpected or not the presence of liquid in the gas phase; this led to the writing of the ISO 2012. The uncertainty quoted for using...
