Investigating Enhanced Oil Recovery Techniques in Ultratight Reservoirs Through Coreflooding Experiments

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
This study explores the efficacy of various enhanced oil recovery (EOR) techniques, including water alternating gas (WAG), gas alternating water (GAW), alkaline surfactant polymer (ASP), and chemical WAG (CWAG) injections. Through coreflooding tests and analysis, we assess their effectiveness in mobilizing and displacing trapped oil in reservoirs.

An Ethane-Based CSI Process and Two Types of Flooding Process as a Hybrid Method for Enhancing Heavy Oil Recovery

Energies
Combining multiple secondary oil recovery (SOR)/enhanced oil recovery (EOR) methods can be an effective way to maximize oil recovery from heavy oil reservoirs; however, previous studies typically focus on single methods. In order to optimize the combined

Experimental Study of Imbibition Characteristics During the Soaking Stage After Fracturing in Tight Reservoirs

Energy Science &Engineering, Volume 12, Issue 12, Page 5418-5428, December 2024.
ABSTRACT The soaking stage is vital for oil production after fracturing in tight reservoirs. However, the roles and contributions of spontaneous imbibition (SI) and forced displacement imbibition (FDI) during this stage are poorly understood. This study gave an in‐depth insight on the imbibition characteristics during the soaking stage under non‐zero ...

Identification of water-cut dynamics in a producing well after breakthrough of a water-induced fracture

Известия высших учебных заведений: Нефть и газ
Water-induced fractures created during water injection can connect injection and production wells. However, the fraction of produced water often increases significantly only after an initially moderate response following breakthrough. We hypothesize that
