Object methods of geostatistical analysis for facies modeling

open access: yesИзвестия высших учебных заведений: Нефть и газ, 2021
Facies cube is a required part of a static model, especially concerning fields characterized by complicated geological structure. The important quantitative limitations for modeling are facies proportions in the formation volume.

Identification of high-permeability subsurface structures with multiple point geostatistics and normal score ensemble Kalman filter [PDF]

open access: yes, 2017
Alluvial aquifers are often characterized by the presence of braided high-permeable paleo-riverbeds, which constitute an interconnected preferential flow network whose localization is of fundamental importance to predict flow and transport dynamics ...

Similarity measure of sedimentary successions and its application in inverse stratigraphic modeling

open access: yesPetroleum Science, 2017
This paper presents a unique and formal method of quantifying the similarity or distance between sedimentary facies successions from measured sections in outcrop or drilled wells and demonstrates its first application in inverse stratigraphic modeling. A

Improved groundwater modeling by incorporating geological information from hydrogeological sections

open access: yesAcque Sotterranee, 2023
Geological cross-sections are usually employed in the hydrogeological model conceptualization, but their usage may not be easily exploited in subsequent modeling phases.

Stochastic Facies Modeling of the Lower‐Burdekin Delta Aquifer Based on Lithological Interpretation From Legacy Boreholes

open access: yesWater Resources Research
The spatial heterogeneity of aquifer properties plays an important role in the movement of groundwater and contaminants. The characterization of heterogeneity from field observations is often needed to develop groundwater models used to inform management

Natural history of liver disease in a large international cohort of children with Alagille syndrome: Results from the GALA study

open access: yesHepatology, EarlyView., 2022
Natural history of liver disease in a large international cohort of children with Alagille syndrome: Results from the GALA study. Abstract Background and Aims Alagille syndrome (ALGS) is a multisystem disorder, characterized by cholestasis. Existing outcome data are largely derived from tertiary centers, and real‐world data are lacking.

3-D geological modeling for tight sand gas reservoir of braided river facies

open access: yesPetroleum Exploration and Development, 2015
Considering the poor applicability of conventional geological modeling to tight sand gas reservoir in braided river facies, a modeling method of “multi-stage constraints, hierarchical facies control and multi-step modeling” was put forward taking Sulige ...

Application of facies-controlled modeling technology to the fault-block A11 in A'Nan Oilfield

open access: yesPetroleum Exploration and Development, 2008
The fault-block A11 in the A'Nan Oilfield of the Erlian basin is now at a high water-cut period, and its reservoir heterogeneity has severely affected development results.
