Insights into Hydraulic Fracturing of a Horizontal Well in a Naturally Fractured Formation

SPE Annual Technical Conference and Exhibition, 1988
Abstract Horizontal wells are thought to be necessary in formations with low-permeability such as the Devonian shales to increase natural gas recovery and to reduce the risk of drilling a dry hole. In a horizontal well, the bore hole crosses multiple natural fractures in the reservoir.

Acid Fracturing: The Effect of Formation Strength on Fracture Conductivity

SPE Hydraulic Fracturing Technology Conference, 2009
Abstract A few studies considered the role of rock strength on fracture conductivity retained at elevated closure strengths. Based on experimental results and field data, many correlations were derived with a consideration of both the surface roughness and rock mechanical properties. These studies found that acid fracture conductivity is

Modeling of complex hydraulic fractures in naturally fractured formations

2023
The formation of complex fracture networks with nonplanar and multistranded shapes, due to the interaction between hydraulic and natural fractures, has been indicated by cores, mine-back experiments, and multiple numerous fracture diagnostic techniques.

Guidelines for the Design of Fracturing Treatments for Naturally Fractured Formations

Proceedings of European Petroleum Conference, 2002
AbstractNatural fractures are present in many oil and gas producing reservoirs and largely contribute to the productivity of those reservoirs. Natural fractures, however, also complicate drilling, completion, and/or work-over operations. Hydraulic fracturing treatments are particularly sensitive for the presence of natural fractures as the hydraulic ...

Impact of Fracturing and Fracturing Techniques on Productivity of Unconventional Formations

SPE/EAGE European Unconventional Resources Conference and Exhibition, 2012
Abstract Unlocking the potential of unconventional gas reservoirs can change the balance and future of the oil industry. Unconventional gas reservoirs can be tight-gas, coalbed methane (CBM), or shale reservoirs. Economic production of any of these three types requires the creation of multiple fractures from a long horizontal well ...

Formation and Fracture Characterization by Inversion of Fracture Treatment Records

Proceedings of SPE Annual Technical Conference and Exhibition, 1993
ABSTRACT The design of hydraulic fracture treatments requires reliable determination of in-situ parameters. The algorithm presented in this paper is a method of formation and fracture characterization based on the application of a formal inversion procedure to fracture treatment data records, collected during calibration treatments ...

Hydraulic Fracturing of Naturally Fractured Tight Gas Formations

SPE Middle East Unconventional Gas Conference and Exhibition, 2011
Abstract A workflow is presented for modeling actual hydraulic fracturing jobs in tight gas formations of the Western Canada Sedimentary Basin (WCSB). Matching of hydraulic fracture length and resulting gas production from past jobs provides a learning curve that allows design optimization of future fracturing jobs.

Modeling of complex hydraulic fractures in naturally fractured formation

Journal of Unconventional Oil and Gas Resources, 2015
Abstract 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 the technical challenges involved in modeling complex hydraulic fracture networks, the interaction between a hydraulic fracture and a natural fracture, and ...

Formation of fracture ‘lances’ in glass

Engineering Fracture Mechanics, 1969
Abstract The development of lance-like fracture facets in glass is quantitatively investigated. Fracture lances are produced by the superposition of tensile (mode I) and anti-plane shear (mode III) loading and are formed as a result of piecewise adjustment of the crack plane to changes in the directions of the maximum principal stress at the crack ...
