Abstract: Frequent well shut-ins and production cycles associated with a hydraulic fracturing job affect proppant-packs' behaviour within the fractures. In this study, 20/40 mesh-size range of four proppant type viz. sand, resin-coated sand (RCS), intermediate strength proppant (ISP) and high strength proppant (HSP), is examined under cyclic loading conditions. The load cycled between 50% of rated stress of each proppant type to the maximum value, and the numbers of cycles considered were 1, 3, 5 and 10. In the first cycle, the quantity of fines formed was 7.138%, 0.187%, 2.151% and 2.106% for sand, RCS, ISP and HSP, respectively. In the tenth cycle, the total fines further increased to 34.004%, 13.714%, 26.305% and 26.305%, respectively. In RCS, breaking down of larger proppants in terms of quantity per cycle is lesser as compared to sand, HSP and ISP. Formation of a thick cured bonding between the RCS particles plays a significant role. [Received: April 11, 2023; Accepted: June 11, 2023]
