straight fracture path. The shear displacement that is generated on the fracture path leads to self propping. We conclude that it is practical to place unpropped and propped opening mode fractures into naturally fractured rock to reduce flow impedance of the well and improved stimulation of EGS reservoirs. INTRODUCTION for clastic reservoirs measure fracture properties only in the vicinity of the well(s) and attempt to predict the distribution of fractures based on indirect observations or assumptions. In naturally fractured carbonate reservoirs, these methods will not provide sufficient data to define the entire reservoir framework. ing capacity of a naturally fractured reservoir is governed by matrix-fracture fluid transport capacity, which is called interporosity flow. To describe flow in naturally fractured reservoirs, double pomsity model has been widely used. Fig. 1.1 shows the schematic of a naturally fractured reservoir and its double porosity idealiza- tion.

This book addresses some of the challenges and advances in knowledge, approaches, concepts, and methods used to characterize the interplay of rock matrix and Hydraulic Fracturing of Naturally Fractured Reservoirs.

Conventional opening mode hydraulic fracturing has. About the Author(s) Dr. Roberto Aguilera is president of Servipetrol Ltd. and an Adjunct Professor in the Chemical and Petroleum Engineering Department at the University of Calgary, where he concentrates in teaching about the theoretical and practical aspects of naturally fractured reservoirs. He is a petroleum engineering graduate from the Universidad de America at Bogota, Colombia and holds Naturally fractured reservoirs present unique and specialized challenges to hydrocarbon extraction. Naturally Fractured Reservoir Characterization seeks to confront many of these challenges by providing an introduction to the engineering and geological character of naturally fractured reservoirs. The focus is on understanding fractures in a From the above, we can see that an e cient method for determining water in?ux in naturally fractured reservoirs is still lacking. To improve this situation, based on a mathematical model of naturally fractured reservoirs, a new global search algorithm is proposed to calculate water in?ux. commonly used in modeling these naturally fractured reservoirs. In this model, the fluid flows through the fracture system in the reservoir, while matrix blocks are segregated by the fractures and act as the fluids sources for them. This model was originally developed for liquid in naturally fractured systems Most naturally fractured reservoirs I am familiar with are characterized by low matrix porosities (less than 10%) and low matrix permeabilities (less than 1 md). For these reservoir characteristics it is difficult to place a reasonable certainty of volumetric estimates of original hydrocarbons-in-place and reserves.
