Experimental study of wettability alteration and spontaneous imbibition in Chinese shale oil reservoirs using anionic and nonionic surfactants

Journal of Petroleum Science and Engineering, 2019
Wettability alteration exhibits a significant potential to improve the oil recovery of shale reservoirs by means of spontaneous imbibition through shifting the rock wetness from oil-wet to water-wet.

Experimental and Numerical Study on CO2 Sweep Volume during CO2 Huff-n-Puff Enhanced Oil Recovery Process in Shale Oil Reservoirs

Energy & Fuels, 2019
CO2 huff-n-puff has been proven to be the most effective enhanced oil recovery (EOR) method in shale oil reservoirs. The injected CO2 will replenish reservoir energy and penetrate the reservoir matrix to extract oil.

Simulations of Thermal Upgrading Methods for Oil Shale Reservoirs

SPE Kuwait International Petroleum Conference and Exhibition, 2012
Abstract This paper analyzes reaction and thermal front development in porous reservoirs with reacting flows, such as those encountered in shale oil extraction. A set of dimensionless parameters and a 3D code are developed in order to investigate the important physical and chemical variables of such reservoirs when heated by in situ ...

Evaluation of Surfactants for Oil Recovery Potential in Shale Reservoirs

SPE Improved Oil Recovery Symposium, 2014
Abstract Most shale reservoirs (e.g., Bakken Shale and Eagle Ford) have a low permeability, low porosity, and oil-wet character with natural fractures. As a result, the oil recovery factors are very low, only a few percent of original oil in place.

Dimensional Analysis of CO2 Injection in Shale Oil Reservoirs

SPE Annual Technical Conference and Exhibition
Abstract Carbon dioxide (CO2) injection effectively enhances oil recovery from shale reservoirs while potentially storing CO2. Several operational and reservoir parameters impact the oil recovery factor and CO2 storage efficiency. Rather than conducting extensive simulations through sensitivity analysis, dimensional analysis offers ...

Using geomechanics for optimizing productivity in shale oil reservoir

19th Congress of the Brazilian Geophysical Society - Proceedings
This study presents an integrated characterization to evaluate the geomechanical properties of the carbonate oil shale of the Pimienta formation, a Tithonian Superior Jurassic Reservoir. To build the geomechanical model for optimizing stimulation design for increasing productivity an extensive laboratory tests used to calibrate geomechanical properties
