Crushing characteristics of four different proppants and …
The laboratory conductivity tests at a proppant loading of 2 lb/ft 2 give a proppant pack height approximately half the height measured from the crush test (proppant loading 4 lb/ft 2). For example, at 40 MPa, the proppant height from the crush test is 10.97 mm for the mesh 40/70 Genoa sand and is 11.71 mm for the mesh 30/50 …
Impacts of Proppant Flowback on Fracture Conductivity in …
The proppant filling layer may form a hemispherical "sand arch" near the perforation, and then, the existence of the sand arch directly affects the filling effect of the proppant. It is complex for the proppant to flow back. The proppant that flow back from the facture will erode the proppant pack, resulting in more proppant to flow back.
Acoustic Emission Monitoring Elucidates Proppant Pack
To study this problem, numerous proppant crush tests were performed according to this standard with the inclusion of acoustic emission (AE) monitoring.

surface friction. Proppant crush tests are one method to determine some of these physi‐ cal proppant parameters under in-situ conditions. Standardized crush test procedures are outlined in API RP-56, RP-58 and RP-60 and are summarized in ISO 13503-2. The intent of these tests is to provide a comparison of the physical
Frac Sand and Proppant Size and Shape
The size range of the proppant is very important. Typical proppant sizes are generally between 8 and 140 mesh (106 µm - 2.36 mm), for example 16-30 mesh (600 µm – 1180 µm), 20-40 mesh (420 µm - 840 µm), 30-50 mesh (300 µm – 600 µm), 40-70 mesh (212 µm - 420 µm) or 70-140 mesh (106 µm - 212 µm). When describing frac sand, the ...
PropShield Proppant Flowback Control Additive
The PropShield additive continues to be used successfully in the Permian Basin, Anadarko Basin, and Viking formation to control proppant flowback. Compared to offset wells, the PropShield additive user experienced: 50% less proppant returned during drillout. 80% less proppant flowback once the wells were put on production.

Recent progress on proppant laboratory testing method
Proppant transport plays a vital role in the success of HF operation. Poor proppant transport leads to poor proppant settlement, as it leads to early settlement of proppant at the lower region of the created fracture. This results in shorter effective fracture length and inadequate coverage of the productive zone's total height ((Economides, 2009).
