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

Designing Orthogonal‐Arc Trajectories for Horizontal Wells to Reduce Drilling Cost in Development of Shale Oil/Gas Reservoirs

Energy Science &Engineering, EarlyView.
Designing 3‐dimensional (3D) horizontal well trajectories is critical for enhancing drilling efficiency in shale reservoirs. This paper proposes an innovative Orthogonal‐Arc Trajectory (OAT) for 3D horizontal wells, which employs a single constant curvature in the curved section.

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 ...

Study on Wax Deposition Law in Daqing Gulong Shale Oil [PDF]

E3S Web of Conferences
Daqing Gulong shale oil exhibits elevated wax content, a high wax precipitation point, and a high freezing point. However, its oil density and viscosity are relatively low, making it susceptible to wax crystal precipitation. The risk of pipeline clogging

A Reproducible SEM Surface Imaging Protocol for Monitoring Microstructural Changes During Gas–Rock Interactions

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Reliable characterization of mineralogical and textural changes in rock samples is essential for understanding fluid–rock interactions, particularly in experimental studies simulating subsurface conditions. This study presents a reproducible protocol for scanning electron microscopy (SEM) analysis of rock surfaces before and after exposure to ...

Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.
