Lab and Field Experimental Infrastructures
Long-term safe disposal of high-level radioactive waste (HLW) is a challenging task for countries with nuclear power production. Due to its high...
-
Introduction
For the disposal of high-level radioactive waste in deep geological formations, different host rocks (rock salt, crystalline and clay rock) are...
-
Model Analysis
We employ the ThermoRichardsMechanics (TRM) process, Wang et al. (2010) implemented in OpenGeoSys (OGS), Bilke et al. (2019). The process captures a...

Introduction
Compared with coal and oil, natural gas is clean and efficient, flexible in transportation and operation.
-
Constant Flow Injection
The hydro-mechanical coupling is one of the research hotspots in the fields of petroleum, mining and tunneling engineering.
-
Hydraulic Fracturing and Rock Mechanics
This open access book is the first to consider the effect of non-uniform fluid pressure in hydraulic fractures. The book covers the key topics in the...
-
Constant Pressure Injection
In practical hydraulic fracturing, limited by the operating power of the syringe pump and long transportation of pipelines, it is often difficult to...
-
Fracture Interaction Behaviors
Problems arising from hydraulic fracturing involve the nonlinear coupling of rock deformation and fluid flow, the nonlocal character of the fracture...
-
Formation of Complex Networks
When a hydraulic fracture interacts with multiple natural fractures (such as bedding planes, faults, weak interlayers, and formation interfaces) in...
-
Fracture Initiation
Field in-situ constant-flow hydraulic fracturing test is an important technique to determine the tectonic stress field. Classical hydraulic...

Reservoir Characteristics
Organic matter-rich Marine shale is mostly gray-black stone-containing carbon or silica-rich rock phase.
-
Fracture Propagation
In previous theories regarding hydraulic fracture propagation, it is usually assumed the fluid pressure within the hydraulic fracture is constant in...
-
Rock Mechanics in Hydraulic Fracturing Operations
Rock, fracture and fluid mechanics are crucial elements in understanding and engineering design of hydraulic fracture treatments.

Wind Energy Basics
During recent history of mankind primary energy was mainly based on fossil sources like coal, oil and natural gas. There is a broad consensus that a...
-
Drivetrain
As mentioned Sect. 2.9 most wind turbines have three blades and a tower and therefore different types of different manufacturers look very much...
