Geometric nature of hydraulic fracture propagation in naturally-fractured reservoirs

Computers and Geotechnics, 2017
Abstract The geometry of hydraulic fracture propagation in the absence and presence of natural fractures in reservoirs was studied. The results revealed a marked influence of natural fractures on the symmetry of fracture propagation observed for rock free of natural fractures.

Sternal fractures — The natural history

Annals of Emergency Medicine, 1988
A five-year retrospective study was undertaken to analyze the natural history of sternal fractures and to scrutinize the current method of management. Sixty-six patients with documented sternal fractures were evaluated. The most common mechanism of injury was motor vehicle accidents (59%). Most of these victims did not wear seat belts.

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.

Hydraulic Fracturing in a Naturally Fractured Reservoir

International Petroleum Conference and Exhibition of Mexico, 1994
Abstract Hydraulic fracturing of wells in naturally fractured reservoirs can differ dramatically from fracturing wells in conventional isotropic reservoirs. Fluid leakoff is the primary difference. In conventional reservoirs, fluid leakoff is controlled by reservoir matrix and fracture fluid parameters.

Natural Fracture Prediction for Discrete Fracture Modelling

Proceedings, 2014
There are many uncertainties in the modelling of discrete fracture networks; largely due to their intense spatial variation and a lack of direct integration between interpreted fracture data at the well level and seismic scale fault interpretations. The method described addresses these two major challenges and demonstrates how these inputs can be used ...

Are natural fractures pervasive?

2021
Fractures and their connectivity are essential for fluid flow in low perme-ability formations. Abundant outcrops can only provide two-dimensional (2D) information, but subsurface fractures are thre...

Detection and Characterization of Fractures in Naturally Fractured Reservoirs

Proceedings of SPE Annual Technical Conference and Exhibition, 2000
Abstract Imaging log, sonic log, optical microscopy, NMR, MRI, and tomography have greatly enhanced the possibility of measuring fracture geometric characteristics. However, the fracture hydraulic width and permeability can only be evaluated from dynamic data revealing production or adsorption along the wellbore.

Fracture Design Considerations in Naturally Fractured Reservoirs

International Meeting on Petroleum Engineering, 1988
ABSTRACT The ability to effectively enhance production through hydraulic fracturing is dependent on an accurate description of the reservoir production mechanism(s). Fracture designs may differ greatly depending on the production mechanism(s).

Naturally Fractured Reservoirs

2019
Currently, there are numerous of authors defined the fracture from a different perspective, However, from the geo-mechanical viewpoint; a fracture is defined as a surface in which a loss of solidity has taken place.

UNCONVENTIONAL EXPLORATION FOR NATURAL FRACTURES

Proceedings of SPE Unconventional Gas Recovery Symposium, 1980
Abstract This is a progress report on the evaluation of a new unconventional exploration technique for locating the natural fracture reservoirs in the Devonian - Ohio Shale. Five PHASE I tests have been drilled, cored, logged, cased and are currently being tested.
