Paper Number: SPE-191406-MS
... found to result in sand production were identified. The sand production model was run to verify the role played by different factors. It is shown that completion design, rock strength and post failure behavior of the rock are key factors responsible for the observed sanding in these wells. In addition...

... rock, when its stress exceeded rock strength. This hypothesis can only work when drillstring collides with wellbore wall only one time and applies stress above rock strength. But, in real drilling, when drillstring vibrates at one of its harmonic frequencies, drillstring will displace away from its...

... communication. A key perforating parameter is the perforation tunnel depth of penetration (DoP). A new paradigm of DoP modeling relies on shaped charge characterization in the laboratory under a range of rock strength and stress; however, most available data are for rock strength or unconfined compressive...
