Sustainability of athletic field turf comparing organic and synthetic practices under two heights of cut

open access: yesCrop Science, Volume 65, Issue 1, January/February 2025.
Abstract Long‐term comparisons over several years between organic and synthetic management are lacking in sports turf research. Our objective was to investigate playing surface qualities and soil properties over an 8‐year period. For this trial, Kentucky bluegrass (KBG, Poa pratensis L.) sod was established and annually inter‐seeded with perennial ...

Prediction of Heavy Oil Production Based on Geomechanical Analysis in Entire Lifecycle of SAGD

open access: yesEnergy Science &Engineering, Volume 13, Issue 1, Page 344-354, January 2025.
A new mathematical model of crude oil production‐geomechanical coupling was established for three stages of the SAGD life cycle (steam chamber breakthrough stage, rising stage, and lateral dilation stage). The influence of the dynamic evolution of rock porosity and permeability on production was fully considered through the sensitivity coefficient of ...

Impact of stockpiling on soil fungal communities and their functions

open access: yesRestoration Ecology, Volume 33, Issue 1, January 2025.
Fungal communities are important components of soil biology and play crucial roles in multiple ecosystem functions and services; therefore, they can be used as effective indicators of soil function in stockpiled reclamation soils. We profiled the fungal communities of seven stockpiles of different ages (0.5, 1.5, 2, 5, 7, 11, and 28 years old) at ...

Investigation of Steam Assisted Gravity Drainage (SAGD) and Expanding Solvent-SAGD (ES-SAGD) Processes in Complex Fractured Models: Effects of Fractures' Geometrical Properties

open access: yes, 2011
The Steam Assisted Gravity Drainage (SAGD) process has been studied theoretically and experimentally in conventional models and reservoirs and is found a promising EOR method for certain heavy oil reservoirs, but its applicability for fractured systems ...

Frequency and Outcomes of Acute‐on‐Chronic Liver Failure in Nonelective Cirrhotic Patients Admitted to a Brazilian ICU: A Single‐Center Retrospective Study

open access: yesCanadian Journal of Gastroenterology and Hepatology, Volume 2025, Issue 1, 2025.
Introduction: Acute‐on‐chronic liver failure (ACLF) is a severe complication of cirrhosis characterized by acute decompensation (AD), organ failure(s), and high mortality. Aims: To investigate the frequency and the clinical course of ACLF in intensive care unit (ICU) patients at different time points, using CLIF‐C and NACSELD criteria as well as to ...

Testing and History Matching ES-SAGD (Using Hexane)

open access: yes, 2010
For the first time, we present in public domain, experimental and history-matched results of 2D scaled laboratory testing of ES-SAGD with hexane as the co-injected solvent.

THE IMPACT OF SHALINESS AND WELL PAIR SPACING IN THE SAGD PERFORMANCE

open access: yes, 2023
Steam Assisted Gravity Drainage (SAGD) is a common thermal recovery technology that uses steam to heat and extract oil from bitumen reservoirs. It consists of an upper horizontal injector and a lower horizontal producer. Varied lateral extent, thickness,

History Matching Reservoir Models With Many Objective Bayesian Optimization

open access: yesApplied AI Letters, Volume 5, Issue 4, December 2024.
Billion grid cell reservoir models for predicting subsurface fluid and rock behaviours can are pushing the limits of computational resources. History matching is one of the primary time‐consuming tasks and as models get larger the number of parameters to match increases, and the number of objective functions increases.
