A comparison of two sanding criteria in physical and numerical modeling of sand production

Sand production during the extrusion of hydrocarbons from geological formations: A review

“…of applied axial stress on sand production observed by Nouri et al (2006), and indicates that increasing stress causes sand production to be significantly enhanced. According to these researchers, sand production can be initiated once tensile stresses exceed the tensile strength of the disaggregated material, or when the pressure gradient of the elements at the cavity face exceeds the UCS of the disaggregated material.…”

“…Therefore, when production starts from the reservoir, sand particles move from the reservoir into the well along with the hydrocarbon flow. This is commonly known as "sand production" in the petroleum industry (Nouri et al, 2006;Ranjith et al, 2013). From the geotechnical point of view, the mechanical stability of bore-wells is of critical importance for the petroleum drilling and recovery process.…”

Screening of Geomechanical Risks for Malaysian Development Field

“…They studied stress state near a sand arch by considering steady state and incompressible fluid flow. This is done in terms of wellbore pressure, drawdown, frictional angle and formation rock cohesion [15].…”

New method for estimating unconfined compressive strength (UCS) using small rock samples

“…Even the new developed indirect USC estimation methods such as block punch index test (Sulukcu and Ulusay;, core strangle test (Yilmaz; 2009), nail penetration test (Kayabali and Selcuk;2009) Due to lack of appropriate rock samples, real-time monitoring of the drilled rocks strength parameters is one of the most important geotechnical problems under the restricted sampling condition. The real time monitoring of mechanical properties of drilled formations during the long term deep oil and gas well excavation projects can be vital for estimation of well wall stability (Zausa et al;1997;Jaramillo;2004), formation sand production (Nouri et al;2005), drill bit selection (Uboldi et al;1999) and drillability of formations (Yarali and Soyer;. (Ringstad et al;1998).…”
