Asymmetrically Propped Hydraulic Fractures

SPE Production & Facilities, 1996
SummaryMapping during and after mining of four hydraulic fractures placed in the German Creek coal seam of the Bowen Basin in Queensland, Australia, revealed that in all four cases the fractures were propped asymmetrically. Three treatments resulted in vertical fractures and one resulted in a T-shaped but mostly horizontal fracture.

Resolving Created, Propped, and Effective Hydraulic-Fracture Length

SPE Production & Operations, 2008
Summary Recent advances in hydraulic-fracture-mapping technologies have provided a wealth of information on the created fracture length in numerous geologic settings. Before having such measurements, fracture length was estimated using "uncalibrated" fracture-propagation models, but there was significant uncertainty in the results that ...

Stimulation of Conventional Geothermal Wells with Propped Fractures

SPE EuropEC - Europe Energy Conference featured at the 83rd EAGE Annual Conference & Exhibition, 2022
Abstract Conventional hydrothermal ("low enthalpy") geothermal reservoirs are already being developed in the Netherlands as a source of heat for greenhouses, district heating. Many of these wells are left with a positive skin after being drilled, and could therefore benefit from stimulation.

Propped Fracturing in Deep Naturally-Fractured Tight Carbonate Reservoirs

SPE Russian Petroleum Technology Conference, 2018
Abstract Over the last ten years, thirty wells were performed by proppant fracturing in deep naturally fractured tight carbonate reservoir in Tarim oilfield, including twenty-two hydraulic fracturing wells and eight acid-carrying-proppant fracturing wells.

Detecting the propped fracture by injection of magnetic proppant during fracturing

Geophysics, 2019
ABSTRACT Hydraulic fracturing is key to enhancing the productivity of shale and tight hydrocarbon reservoirs, as well as geothermal resources from hot dry rock. Assessing the range and efficiency of hydraulic fracturing is very important for onsite fracturing operations and decision making on subsequent fracturing plans and well ...

EXPERIMENTAL EVALUATION OF FRACTURING FLUID INTERACTION WITH TIGHT RESERVOIR ROCKS AND PROPPED FRACTURES

Proceedings of Symposium on Low Permeability Gas Reservoirs, 1979
Abstract Prediction of gas well production after a Massive Hydraulic Fracture (MHF) treatment is essential for economic assessment of the planned stimulation. Present accepted techniques of predicting the Present accepted techniques of predicting the increase in production (stimulation ratio) are based on the ...

Propping Agent Transport in Horizontal Fractures

Journal of Petroleum Technology, 1966
Abstract This laboratory flow study covers propping agent transport in horizontal fractures as influenced by the characteristics of the propping particles, fluid and fracture. Correlations are presented for the transport of particles, deposition and fingering through dunes.

Horizontal Fracture Design Based on Propped Fracture Area

Journal of Petroleum Technology, 1965
Abstract Present fracture design procedures are based on the total fracture area created. A method to distinguish between total area and the propped or effective fracture area has not been available. This paper presents a solution to this problem, applicable to horizontal fractures.

Using Tracers To Evaluate Propped Fracture Width

SPE Eastern Regional Meeting, 1993
Abstract Many production engineers are beginning to use threedimensional (3-D) fracture propagation models to design and analyze hydraulic fracture treatments. To use a 3-D model, one must define the layers that comprise the reservoir and develop detailed datasets that accurately describe the layers.1,2,3 The data that are critical for ...

The Impact of Proppant Retardation on Propped Fracture Lengths

Proceedings of SPE Annual Technical Conference and Exhibition, 2005
Abstract A model for the velocity of proppant particles in slot flow is presented. The proppant is either retarded or accelerated relative to the fluid depending on the ratio of the proppant size to the fracture width. It has been found that when this ratio is small, the proppant travels faster than the average fluid velocity at that ...
