Experimental study on initiation and propagation of hydraulic fractures in stratified shale oil reservoirs

Journal of Petroleum Exploration and Production Technology
The bedding planes of the Gulong shale oil reservoir in Daqing, China are extremely developed, which causes the hydraulic fractures to extend excessively in the horizontal direction while their longitudinal propagation is limited. In order to improve the

Intelligent prediction and integral analysis of shale oil and gas sweet spots

Petroleum Science, 2018
Shale reservoirs are characterized by low porosity and strong anisotropy. Conventional geophysical methods are far from perfect when it comes to the prediction of shale sweet spot locations, and even less reliable when attempting to delineate ...

Potential shale oil recovery methods in the Green River Formation and associated environmental problems [PDF]

, 1980
The United States faces a serious energy crisis and needs to develop new long term domestic sources of energy. One important and untapped source is oil shale. Tapping this resource is an alternative way to lessen U.S. dependence on foreign oil and become

N2 influences on CH4 accumulation and displacement in shale by molecular dynamics

Scientific Reports
N2 is generally employed as a displacement agent to enhance gas recovery in shale gas-bearing reservoirs. However, the primary displacement mechanism in the subsurface still needs to be clarified due to the characteristics of shale reservoirs with low ...

Numerical investigation of the correlations of hydraulic and elastic characteristics in diverse carbonate rock types

Deep Underground Science and Engineering, EarlyView.
We use the linear Boolean model and the discrete Fourier transformation approach to generate various carbonate rocks. The lattice Boltzmann method and the finite element method are applied to calculate permeability and elastic wave velocity, respectively.
