Canadian 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 ...

History Matching Reservoir Models With Many Objective Bayesian Optimization
Applied 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.

The relationship between the secondary vascular system and the lymphatic vascular system in fish
Biological Reviews, Volume 99, Issue 6, Page 2108-2133, December 2024.ABSTRACT New technologies have resulted in a better understanding of blood and lymphatic vascular heterogeneity at the cellular and molecular levels. However, we still need to learn more about the heterogeneity of the cardiovascular and lymphatic systems among different species at the anatomical and functional levels.

How to Plan a SAGD Project, If You Must…
, 2018 Steam-Assisted Gravity Drainage (SAGD) is widely used in Alberta for recovering bitumen from oil (tar) sands. A variation of the same has had some success in heavy oils as well.

, 2017 Reservoir heterogeneities (i.e., lean zones or shale layers) impact the performance of SAGD (steam assisted gravity drainage) processes. The lean zones, which have a water saturation of more than 50%, have been reported by several oil sands fieldsduring ...

Energy and Environment Research, 2013 Steam Assisted Gravity Drainage (SAGD) has been proved to be an effective method in producing from extra heavy oil or bitumen resources. The main recovery mechanism in this process is viscosity reduction by introducing heat into the reservoir. The Solvent Co-Injection processes (SCI) or Expanding Solvent SAGD (ES-SAGD) are alternative methods to the ...

Partial Upgrading of Bitumen at SAGD Wellsite
, 2010 The high-conversion soaker cracking (HSC) process, an advanced continuous thermal cracking, has been used commercially for more than 20 years at a refinery converting heavy oil to valuable lighter distillates. The residue from the process is the heaviest

Impact of Oil Viscosity Gradient Presence on SAGD
, 2010 The presence of an oil viscosity gradient appears to be a real phenomenon in the field and its influence on the SAGD process has been studied by various researchers.

Senlac, The Forgotten SAGD Project
, 2017 The Senlac SAGD (Steam-Assisted Gravity Drainage) project is Saskatchewan, Canada, does not have the same name recognition as its much bigger brothers in the Alberta Oil Sands but it certainly deserves to be known better.

Estudo da injeção de solvente frio no processo de drenagem gravitacional assistida com vapor e solvente (ES-SAGD) em reservatórios do nordeste brasileiro [PDF]
, 2018 The number of heavy oil or bitumen reservoirs in the world is large. This oil has high viscosity and thus difficult mobility within the reservoir. In Brazil, the state of Rio Grande do Norte stands out, which has a long production of heavy oil through ...
