Study on fluid mobility in shale oil reservoirs considering mineral composition and stress sensitivity

The Physics of Fluids
Shale oil has gradually become an important alternative resource to conventional oil in the world. It is necessary to study the mineral and stress sensitive characteristics of shale oil reservoir to understand the mobility of reservoir fluid.

Selection of hydrocarbon gas for huff-n-puff IOR in shale oil reservoirs

Journal of Petroleum Science and Engineering, 2020
In shale oil reservoirs, cyclic CO2 injection has proven to be effective at recovering significant amounts of oil, however, certain downsides to the use of CO2 exist owing to its corrosive nature and its higher miscibility pressure compared to ...

Application of carbon dioxide injection in shale oil reservoirs for increasing oil recovery and carbon dioxide storage

, 2020
Carbon dioxide (CO2) injection is an enhanced oil recovery method that has the potential to increase oil recovery from unconventional shale reservoirs while also storing a portion of the injected CO2 into the reservoir thus reducing the CO2 environmental

Influencing factors and fracability of lacustrine shale oil reservoirs

Marine and Petroleum Geology, 2019
Abstract Shale oil reservoirs need fracturing in order to achieve commercial productivity. A key factor influencing the fracturing process is shale fracability, which is strictly dependent on rock fabric. In this study, we focused on the lacustrine shale oil reservoirs located in Dongying Sag and in the Northern Jiangsu Basin.

Flow Units: From Conventional to Tight-Gas to Shale-Gas to Tight-Oil to Shale-Oil Reservoirs

SPE Reservoir Evaluation & Engineering, 2013
Summary Core data from various North American basins with the support of limited amounts of data from other basins around the world have shown in the past that process speed or delivery speed (the ratio of permeability to porosity) provides a continuum between conventional, tight-, and shale-gas reservoirs (Aguilera 2010a).

Effect of Pressure on Imbibition in Shale Oil Reservoirs with Wettability Considered

, 2020
Recent studies indicate that there is a great potential for enhanced oil recovery in shale oil reservoirs by altering the matrix wetness to induce spontaneous imbibition.

Characterization of pore size distributions of shale oil reservoirs: A case study from Dongying sag, Bohai Bay basin, China

Marine and Petroleum Geology, 2019
Shale oil reservoirs characterized by complex pore structures typically contain a wide pore size range from nanometers to millimeters. The pore size distribution (PSD) is one of the most critical parameters affecting fluid storage and transport ...

Experimental and numerical study of surfactant solution spontaneous imbibition in shale oil reservoirs

, 2020
Experimental and simulation studies have thus far demonstrated that surfactant-based Enhanced Oil Recovery (EOR) is a feasible method to improve recoveries from initially oil-wet or mixed-wet Unconventional Oil Reservoirs (UORs). The summarized principle

CO2 EOR Mechanisms in Bakken Shale Oil Reservoirs

Carbon Management Technology Conference, 2015
Preliminary studies have been done to characterize rock-fluid properties, and flow mechanisms in the shale reservoirs. Most of these studies, through modifying methods used for conventional reservoirs, fail to capture dynamic features of shale rock and fluids in confined nano-pore space.
