New Mathematical Models for Calculating Proppant Embedment and Fracture Conductivity
SPE Journal, 2012 SummaryProppant embedment plays a significant role in decreasing fracture aperture and conductivity, especially for weakly consolidated sandstones, shale (oil and gas) rock, and coalbeds. Empirical and semiempirical models were usually used to calculate the embedment of proppants.

Abstract Hydraulic fracturing is regarded as an effective tool to stimulate the reservoir and ensure economic production of gas. The process of exploitation of these resources is largely influenced by small spheres called proppants. The main goal of hydraulic fracturing is to generate a wide fracture network in the medium.

Experimental Analysis of Proppant Embedment Mechanism
Chemistry and Technology of Fuels and Oils, 2018Proppant embedment in hydraulic fracturing can reduce remarkably the fracture width and thus damage the fracture conductivity. This paper describes a study of the proppant embedment mechanism. Two groups of experiments were carried out. A proppant embedment mechanism was proposed. An analysis showed that proppant embedment is not an elastic process but

New Experimental Methods to Study Proppant Embedment in Shales
Rock Mechanics and Rock Engineering, 2021Productivity in fractured wells typically declines when severe proppant embedment shrinks the fracture aperture and creates conductivity clogging fines. However, the mechanisms linking embedment to decline are poorly characterized. In the absence of this understanding, very few models take proppant embedment into account when predicting production ...

SPE Production & Operations, 2018 Summary Proppant plays a vital role in hydraulic fracturing in tight oil/gas production because it helps to keep the fractures open during the production process. However, it is common for proppant embedment, the main type of proppant degradation, to occur under high compression load, which greatly reduces the fracture conductivity, and ...

Numerical study of proppant embedment under proppant-coal seam interaction
Powder TechnologyExperimental studies on proppant embedment in coal seams often overlook factors like pulverized coal shedding, leading to inaccuracies. This study developed a numerical model for proppant embedment in coal seams using elastoplastic theory and the material point method (MPM).

Mathematical Modeling of Proppant Embedment and Its Effect on Conductivity of Hydraulic Fracture
SPE Russian Petroleum Technology Conference, 2017 Abstract The proppant embedment into rock during the operation of the hydraulically fractured well is one of the reasons for the production rate decrease. Most researchers analyze this problem on the basis of laboratory experiments and do not take into account the well production data.

The effect of proppant embedment upon the long-term conductivity of fractures
Journal of Petroleum Science and Engineering, 2007Experimental research on proppant embedment in formation core has been done for the first time in China using FCES-100 (Long-Term Fracture Conductivity Evaluation System). In the experiments, the degree of embedment to different cores and the damage to conductivity were studied in the condition of different concentrations and types of proppants.

The Effects of Fracturing Fluids on Shale Rock Mechanical Properties and Proppant Embedment
SPE Annual Technical Conference and Exhibition, 2011 Abstract The development of shale reservoirs has grown significantly in the past few decades, spurred by evolving technologies in horizontal drilling and hydraulic fracturing. The productivity of shale reservoirs is highly dependent on the design of the hydraulic fracturing treatment. In order to successfully design the treatment, a good

Influences of Proppant Embedment and Deformation on Micro-Sized Graded Proppant Injection Scheme
SPE Asia Pacific Oil & Gas Conference and Exhibition, 2020Abstract The method of micro-sized graded proppant injection has been proposed in the industry to increase the size of the stimulated zone in naturally fractured reservoirs, especially CBM. However, big discrepancies between the modelling results of graded proppant injection and the experimental results have been observed.
