Transient pressure analysis of a volume fracturing well in fractured tight oil reservoirs

Transient Pressure Analysis of Pressure Sensitive Naturally Fractured Reservoirs

This paper presents the results of a study with the main aim of investigating the effect of considering the pressure sensitivity of the natural fractures of a fissured formation on the transient pressure analysis of well tests. Two motivations for this study were as follows. First, many (or most in some cases) of the producing reservoirs (geothermal and petroleum) are naturally fractured, showi...

Hydraulic Fracturing of Naturally Fractured Reservoirs

A carefully engineered stimulation that makes use of opening mode fractures is an effective way to reduce injection and production impedance and provide better access for the fluid to enter and promote shearing in the main reservoir volume. We present results from field experiments that mapped the fracture geometry for opening mode hydraulic fractures formed in naturally fractured crystalline r...

Theoretical Analysis of the Mechanism of Fracture Network Propagation with Stimulated Reservoir Volume (SRV) Fracturing in Tight Oil Reservoirs

Stimulated reservoir volume (SRV) fracturing in tight oil reservoirs often induces complex fracture-network growth, which has a fundamentally different formation mechanism from traditional planar bi-winged fracturing. To reveal the mechanism of fracture network propagation, this paper employs a modified displacement discontinuity method (DDM), mechanical mechanism analysis and initiation and pr...
