Natural fractures have long been suspected as a factor in production from shale reservoirs
because gas and oil production commonly exceeds the rates expected from low-porosity …

Hydraulic fractures represent a particular class of tensile fractures that propagate in solid
media under pre-existing compressive stresses as a result of internal pressurization by an …

We review ten historical Enhanced Geothermal Systems (EGS) projects and find that
typically, during injection:(1) flow from the wellbore is from preexisting fractures,(2) …

This work designs an experimental model of tight sandstone with a closed cemented pre-
existing fracture network (CCPF) to explore the influence of closed cemented natural …

Hydraulic fracturing in shale-gas reservoirs has often resulted in complex-fracture-network
growth, as evidenced by microseismic monitoring. The nature and degree of fracture …

This paper presents a general overview of hydraulic fracturing models developed and
applied to simulation of complex fractures in naturally fractured shale reservoirs. It discusses …

Hydraulic fracturing is recognized as the main stimulating technique to enhance recovery in
tight fissured reservoirs. These fracturing treatments are often mapped by use of …

In this paper we present a comprehensive and yet efficient complex fracture network model
that simulates hydraulic fracture networks created during the stimulation treatment and …

We develop a new analytical model, called OpenT, that solves the elasticity problem of a
hydraulic fracture (HF) contact with a pre-existing discontinuity natural fracture (NF) and the …

Microseismic map** (MSM) has shown that the occurrence of complex fracture growth is
much more common than initially anticipated and is becoming more prevalent with the …
