Enhanced Oil Mechanism of WAG in Tight Reservoir
2021Tight reservoir needs new gas injection methods to delay gas channeling for the development of fractures, which result in early gas channeling in continuous gas injection. In this paper, the feasibility of CO2 flooding in tight reservoir core is analyzed, and the mechanism of water alternating CO2 for tight reservoir with fracture development is ...

Steam Injection in Tight Oil Reservoir
SPE Improved Oil Recovery Conference, 2018Abstract Steam injection—a thermal-based enhanced oil recovery (EOR) process—is used to improve fluid mobility within a reservoir, and it is well known that it yields positive results in heavy-oil reservoirs. In theory, steam injection has the potential of being applied in light-oil reservoirs to enable vaporization of in-situ reservoir ...

Wettability Alteration in a Tight Oil Reservoir
Energy & Fuels, 2013In fractured reservoirs, the efficiency of water flood is governed by spontaneous imbibition of water into oil-containing matrix blocks. When the matrix is oil-wet or mixed-wet, little oil can be recovered by imbibition. The objective of this work is to identify chemicals that can be added to the injection water that can induce imbibition into an ...

Multimodal reservoir porosity simulation: An application to a tight oil reservoir
Journal of Applied Geophysics, 2014Abstract At appraisal stage of a reservoir characterization, a key step is the inference of the reservoir static properties, such as porosity. In this study, we present a new nested workflow that optimally integrates 3D acoustic impedance and geophysical log data for the estimation of the spatial distribution of reservoir porosity, which is applied ...

Multiphase Linear Flow in Tight Oil Reservoirs
SPE Reservoir Evaluation & Engineering, 2016Summary The main objective of this work is to gain a general understanding of the performance of tight oil reservoirs during transient linear two-phase flow producing at constant flowing pressure. To achieve this, we provide a theoretical basis to explain the effect of different parameters on the behavior of solution-gas-drive ...

Micro/Nanopore Systems in Lacustrine Tight Oil Reservoirs, China
Journal of Nanoscience and Nanotechnology, 2021A nanoscale pore throat system develops extensively in rocks of unconventional reservoirs serving as both source and reservoir rock. The nanoscale pores provide the main storage spaces, accounting for 70% to 80% of the total unconventional tight reservoirs in China.
