Hydraulic-Fracture Propagation in a Naturally Fractured Reservoir

SPE Production & Operations, 2010
Summary We present the results of numerical modeling that quantify the physical mechanisms of mechanical activation of a natural fault because of contact with a pressurized hydraulic fracture (HF). We focus on three stages of interactions: HF approaching, contact, and subsequent infiltration of the fault.

Dynamic fracture propagation in hydraulic re-fracturing

Journal of Petroleum Science and Engineering, 2010
Re-fracturing is important for stimulating low-permeability reservoirs, for the effective production duration after the initial fracturing is short and needs to be stimulated again. However, the fracture configuration caused by re-fracturing affects the re-stimulated production greatly.

Linear stability analysis for propagating fracture

Physical Review E, 1996
To study the stability of mode I (opening-mode) fracture, we consider a two-dimensional system in which a crack moves along the center line of a very wide, infinitely long strip. We compute the first-order response of the crack to a spatially periodic, perturbing shear stress. We assume isotropic linear elasticity in the strip and a cohesive-zone model

Effect of Natural Fractures on Hydraulic Fracture Propagation

SPE European Formation Damage Conference, 2005
Abstract Various fracture interaction criteria were reviewed and a systematic study is presented to analyze the effect of natural fractures on hydraulic fracture propagation. From the literature review, the approach of Warpinski and Teufel was adopted to evaluat the fracture propagation that would occur after a hydraulic fracture ...

Gel Propagation Through Fractures

Proceedings of SPE/DOE Improved Oil Recovery Symposium, 2000
Abstract When gels are used for conformance control in reservoirs, a need exists to determine how much gel should be injected in a given application and where that gel is distributed (i.e., placed) in a naturally fractured reservoir. These parameters depend critically on the properties of gels in fractures.

Hydraulic Fracture Propagation in Pre-Fractured Natural Rocks

SPE Hydraulic Fracturing Technology Conference, 2011
Abstract We conducted a series of hydraulic fracture initiation tests with fractured natural rock samples. The objective is to characterize the interaction between hydraulic fracture initiation and natural fracture infiltration and opening.

Propagation of natural hydraulic fractures

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1997
Abstract This paper is concerned with modeling the propagation of natural hydraulic fractures (NHF). Growth of a NHF is limited by the condition that change of the crack volume during propagation is equal to the volume of the fluid flowing from the rock into the crack. In this paper, we show that formulation of this problem can be reduced to a single

Dynamics of Fracture Propagation

1974
In discussing the fracture of solids under a single application of the load, generally one may differentiate three types of material response. The first is the so-called crystalline shatter of a defect-free crystal with an ideally uniform geometry and under ideally uniform external loads, or fragmentation of defect-free high strength brittle solids.
