Basic characteristics and evaluation of shale oil reservoirs
: Shale oil refers to liquid hydrocarbons existing in free, dissolved or adsorbed states in the effective source rock of mudstones or shales, where some residual oil is retained after hydrocarbon generation and expulsion from the mudstones or shales ...

A workflow for flow simulation in shale oil reservoirs: A case study in woodford shale [PDF]
In recent years, with new technologies of long horizontal wells and staged hydraulic fracturing, the development of unconventional oil and gas reservoirs (i.e., shale gas and shale oil) has gained significant momentum. Due to extremely low permeability, these unconventional formations cannot be produced economically without significant stimulation.

Quantitative Prediction of Natural Fractures in Shale Oil Reservoirs [PDF]
Natural fractures are the key factors controlling the enrichment of shale oil. It is of great significance to clarify the distribution of natural fractures to guide the selection of sweet spots for shale oil. Taking the Qing-1 Member shale oil reservoir in the northern Songliao Basin, China as an example, a new method considering the factors affecting ...

Enhanced oil recovery in shale reservoirs by gas injection [PDF]
The current available technique to produce shale oil and gas condensate is through primary depletion using horizontal wells with multiple transverse fractures. The oil recovery factor is only a few percent. There is a big prize to be claimed in terms of enhanced oil recovery (EOR).
