A new method to measure propped fracture width and proppant porosity in shale fractures

Journal of Petroleum Science and Engineering, 2019
Abstract Hydraulic fracturing is the main stimulation method used to economically produce from shale formations. The method requires the injection of a fracturing fluid at a pressure, which is high enough to fracture the formation, and as a result, improves the well productivity.

Prop Transport in Vertical Fractures

Proceedings of SPE Annual Technical Conference and Exhibition, 1981
ABSTRACT The subject of prop transport in vertical fractures has been much discussed in the literature in the past five years. Yet, there are many questions that remain unanswered. Probably the most difficult question to answer involves particle transport by cross-linked gels.

Propping Fractures with Aluminum Particles

Journal of Petroleum Technology, 1961
Abstract This paper presents information on the use of a new propping agent (malleable aluminum particles) which has been used successfully for producing high-conductivity fractures. The conductivity of a packed fracture depends oil the width of the fracture as well as the permeability of the ...

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.
