- Keywords: hydraulic fracturing ; shale formation ; oil ; oil extraction
- Description
- The Spring 2014 Special Issue of the ARMA e-newsletter is dedicated to geomechanics in petroleum extraction with particular interest to
hydraulic fracturing of shale formations and contains four technical notes.
The lead article, by Paul La Pointe, introduces us to the general field of oil extraction, emphasizing the importance of combining geology and geomechanics in that pursuit. The other three technical notes address different aspects of producing oil from shale formations.

- The Role of Natural Fractures in Shale Gas Production

- Keywords: natural fractures ; shale gas production
- Description
- In this paper we investigate the role played by natural fractures in the gas production process. By applying a new model of the production process to data from many shale gas wells across a number of shale plays in North America, we can for the first time begin to sort out assertion from inference in the role that these fractures play. Specifically, we are able to estimate the magnitude of the fracture surface through which gas is actually produced. We are
able to demonstrate that although it may be commensurate with the expected surface area of
open natural fractures for the ultra-low permeability shallow gas shales, it is in fact com‐
mensurate with a very much smaller area for the deeper gas shales such as the Barnett. Furthermore, given a typical value of the matrix permeability, almost all the gas between the
fractures would have been produced in an uncharacteristically short period of time unless
the producing fractures are 100s of feet apart. The implications of these findings for completion and stimulation strategies will be discussed.

- Differentiating Applications of Hydraulic Fracturing
- J. Adams ; C. Rowe
- Book Title / Journal: Effective and Sustainable Hydraulic Fracturing - Chapter 18
- Year: 2013
- Rock Engineering ; Other Geotechnical
- Keywords: hydraulic fracturing ; rock stress measurements
- Description
- Hydraulic fracturing has received abundant media attention in recent years due to a rapid increase in the use of the technique in combination with horizontal drilling technology to produce oil and gas resources from tight reservoirs. Hydraulic fracturing techniques are also used in a variety of other applications that are unrelated to oil and gas production, including tunnel and dam construction, enhanced geothermal energy, carbon sequestration, groundwater remediation, block cave mining, rock burst mitigation, and water well development.
This paper characterizes a range of hydraulic fracturing applications in terms of the objectives, techniques, and potential for environmental concerns associated with the standard methods. A nomenclature that clearly differentiates discrete applications is presented that is intended to help prevent the lumping of all hydraulic fracturing techniques into a single basket.

- Initiation and Breakdown of an Axisymmetric Hydraulic Fracture Transverse to a Horizontal Wellbore
- S. Abbas ; B. Lecampion
- Book Title / Journal: Effective and Sustainable Hydraulic Fracturing - Chapter 19
- Year: 2013
- Mining ; Other Geotechnical
- Keywords: axisymmetric hydraulic fracture ; hydraulic fracture propagation
- Description
- We investigate the initiation and early-stage propagation of an axi-symmetric hydraulic
fracture from a wellbore drilled in the direction of the minimum principal stress in an elastic
and impermeable formation. Such a configuration is akin to the case of a horizontal well and
a hydraulic fracture transverse to the well axis in an open hole completion. In addition to the
effect of the wellbore on the elasticity equation, the effect of the injection system compressi‐
bility is also taken into account. The formulation accounts for the strong coupling between
the elasticity equation, the flow of the injected fluid within the newly created crack and the
fracture propagation condition. Dimensional analysis of the problem reveals that three di‐
mensionless parameters control the entire problem: the ratio of the initial defect length over
the wellbore radius, the ratio between the wellbore radius and a length-scale associated with
the fluid stored by compressibility in the injection system during the well pressurization,
and finally the ratio of the time-scale of transition from viscosity to toughness dominated
propagation to the time-scale associated with compressibility effects. A fully coupled nu‐
merical solver is presented, and validated against solutions for a radial hydraulic fracture
propagating in an infinite medium. The influence of the different parameters on the transi‐
tion from the near-wellbore to the case of a hydraulic fracture propagating in an infinite me‐
dium is fully discussed.
