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 ...

The Effect of Fracture Surface Roughness on Propped Fracture Conductivity Using 3D-Printed Fracture Surfaces

SPE Western Regional Meeting, 2023
Abstract When rocks are fractured in tension, the fracture surfaces created are rough, with a wide range of surface morphologies possible. In previous studies of propped fracture conductivity using fractured samples, the fracture surface topography was found to have a strong influence on fracture conductivity and stimulation efficiency ...

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 ...

Eco-Friendly Creation of Propped Hydraulic Fractures

SPE Hydraulic Fracturing Technology Conference, 2012
Abstract A novel method for creating short, highly conductive fractures in wells to bypass formation damage has been developed. The method uses relatively small material volumes, low horsepower and pump rate, produces minimal environment effect, and leaves the formation face and proppant pack residue free. Function and application of the

Investigation of Factors for Strengthening a Wellbore by Propping Fractures

SPE Drilling & Completion, 2008
Summary Wellbore strengthening or stress cage implementation has been recognized as an effective means of dealing with lost circulation during drilling operations. One of the mechanisms developed for strengthening a wellbore has been to prop induced and existing fractures with particulate lost circulation materials (LCM) to effectively ...

Propped Fracturing in Tight Carbonates Reservoir – A Case Study

SPE International Hydraulic Fracturing Technology Conference and Exhibition, 2023
Abstract Reservoir properties in the Lekhwair satellite fields targeting carbonate formation (Natih C1) oil reservoir were found to be lesser quality in mobility than prognosed. Post-drilling stimulation was performed using 20% HCl with limited success.

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.

Measurement of Gel Cleanup in a Propped Fracture With Dynamic Fracture Conductivity Experiments

SPE Annual Technical Conference and Exhibition, 2008
Abstract The effect of residual fracture fluid gels on the conductivity of propped fractures has commonly been measured in the laboratory with a static fracture conductivity procedure in which a certain amount of proppant is placed in a fracture conductivity cell, and then fracture fluid is injected into the cell.

The Mechanical Stability of Propped Hydraulic Fractures: A Numerical Study

Journal of Petroleum Technology, 1995
Summary Proppant is sometimes produced along with hydrocarbons in hydraulically fractured petroleum wells. Sometimes 10% to 20% of the proppant is backproduced, which can lead to damaged equipment and downtime. Furthermore, proppant flowback can lead to a substantial loss of fracture conductivity.

Flow Response of Propped Fracture to Repeated Production Cycles

Proceedings of SPE Annual Technical Conference and Exhibition, 1987
ABSTRACT Once a reservoir is hydraulically fractured, the fracture may experience several repeated production/shut-in cycles. Evidence of reduced rate of recovery as wells are placed back on production, has been noted in gas wells that have been exposed to this type of cycling.
