Experimental Investigation of Asphaltene Deposition and its Impact on Oil Recovery in Eagle Ford Shale during Miscible and Immiscible Co2huff-N-Puff Gas Injection [PDF]

, 2022
One of the challenges in extracting oil from unconventional resources using hydraulic fracturing and horizontal drilling techniques is the low primary recovery rate, which is caused by the ultra-small permeability of these resources.

Nanometer‐Scale CO2‐Shale Oil Minimum Miscibility Pressure Calculations Based on Modified PR‐EOS

Geofluids, Volume 2023, Issue 1, 2023., 2023
CO2 flooding is recognized as an efficient method for enhancing shale oil recovery, while CO2‐oil MMP (minimum miscibility pressure) in the micro‐nanoscale is a crucial parameter. This paper presents a method for calculating the MMPs of pure hydrocarbons (C4H10, C6H14, C8H18, and C10H22) and CO2 systems in nanopores (3 nm to 10 nm) with temperature ...

Huff-n-Puff Experimental Studies of CO2 with Heavy Oil [PDF]

Energies, 2019
This work is devoted to CO2 Huff-n-Puff studies on heavy oil. Oil recovery for heavy oil reservoirs is sufficiently small in comparison with conventional reservoirs, and, due to the physical limitation of oil flow through porous media, a strong need for better understanding of tertiary recovery mechanisms of heavy oil exists.

Welfare of domestic birds and rabbits transported in containers

EFSA Journal, Volume 20, Issue 9, September 2022., 2022
Abstract This opinion, produced upon a request from the European Commission, focuses on transport of domestic birds and rabbits in containers (e.g. any crate, box, receptacle or other rigid structure used for the transport of animals, but not the means of transport itself).
