Slotting–directional hydraulic fracturing (SDHF) is a promising technology for extracting
CBM, because it can achieve directional propagation of fractures, and solve the problem of …

Perforation is a key link in well completion. To meet the development requirements of
different types of oil and gas fields, after over ten years of research and development, a …

Hydraulic fracturing is mainly used for increasing large-scale coal seam permeability in coal
mines to exploit coalbed methane and prevent coal and gas outbursts. However …

Sc-CO 2 fracturing would be a potential stimulation method for Hot Dry Rock. A series of Sc-
CO 2 fracturing experiments were performed on granite under different temperature and …

In carbonate fracture-cavity reservoirs, such as the Tahe oilfield in China, natural cavities are
the main storage space of oil. It is critical to control the propagation of hydraulic fractures in …

In this paper, a new numerical simulation tool named TOUGH-FEMM is presented and
applied to model three-dimensional (3D) hydraulic fracturing in porous rock. The fluid flow in …

The pattern and path of hydraulic fracture (HF) from a wellbore circumference have a great
impact on subsequent formation of complex fracture networks highly desired for permeability …

In the traditional, displacement discontinuity method (DDM) simulation of hydraulic
fracturing, the stress intensity factor (SIF) method is usually employed to calculate the …

Perforation is the key to the successful implementation of hydraulic fracturing. The research
on perforation mechanism is of great significance to perforation planning, completion …

Hydraulic fracturing could be a useful method for controlling the propagation path of cracks
near an injection borehole by means of the perforating technique, pre-manufactured cracks …
