A Geocoupling Simulation Method for Fractured Reservoir Production

Geofluids, Volume 2022, Issue 1, 2022., 2022
Reservoir simulation is critical to the design of reservoir development plan and has been extensively used. However, it is challengeable for to simulate the production process for fractured reservoirs, because of the fracture geometry and the fracture deformation. Specifically, three problems need to be solved.

Experimental Evaluation Study on High Temperature Tolerance Foam for Profile Control of Steam Huff‐n‐Puff

Geofluids, Volume 2022, Issue 1, 2022., 2022
In the process of steam huff and puff to develop heavy oil reservoirs, steam channeling is the main factor that restricts the development effect, which causes that the swept area of steam is limited and unable to heat heavy oil adequately. It is important to find an economical and efficient method to prevent steam channeling from happening at steam ...

Recovery mechanisms and formation influencing factors of miscible CO2 huff-n-puff processes in shale oil reservoirs: A systematic review [PDF]

, 2023
Shale oil production is vital for meeting the rising global energy demand, while primary recovery rates are poor due to the ultralow permeability. CO2 huff-n-puff can boost yields by enabling key enhanced oil recovery mechanisms. This review examines the

Mechanism of Surfactant Enhancement of CO2 Displacement Recovery in Interlayer Shale Oil Reservoirs

Geofluids, Volume 2022, Issue 1, 2022., 2022
Aiming at the problem that few studies have been conducted on the combination of multiple media in enhanced oil recovery (EOR), the physical simulation experiment of surfactants + CO2 (SPC) was carried out to analyze the influence of surfactant on the CO2 displacement effect of interlayer shale oil reservoir. The results show that when the displacement

Development and Research Status of Heavy Oil Enhanced Oil Recovery

Geofluids, Volume 2022, Issue 1, 2022., 2022
Heavy oil is an important part of petroleum hydrocarbon energy. With the depletion of conventional crude oil reserves, successful and efficient exploitation of heavy oil resources is becoming increasingly important. This article focuses on the nine relatively mature heavy oil development technologies from the perspectives of the level of understanding ...

Experimental Study on the Oil Recovery Performance of CO2 Huff‐and‐Puff Process in Fractured Tight Oil Reservoirs

Geofluids, Volume 2022, Issue 1, 2022., 2022
In order to investigate energy supply capacity and oil production contribution of near‐fracture and fracture‐free zone in fractured tight oil reservoirs, a series of CO2 huff‐and‐puff tests were designed and carried out in different experimental conditions. A fracture‐matrix long‐core system was established to simulate the near‐fracture zone and matrix

Investigation on the performance between water alternating gas and water huff n puff techniques in the tight oil reservoir by three dimensional model simulation: A case study of Jilin tight oil field

Journal of King Saud University: Engineering Sciences, 2022
Oil production in most of the old reservoirs is expected to decline, and this will create a gap between the supply and demand of oil in the world. Meanwhile, there are still huge volumes of hydrocarbons in unconventional reservoirs.
