Sand prediction at BP has been developed by dividing it into three parts: (1) onset, (2) transient sanding, (3) steady-state sanding. For example, as drawdown is increased in a well in a sand ...
Large amounts of sand production in a short period of time may clog up wells, damage well equipment, and destabilize wellbores due to loss of materials (Climent et al., 2014). On the other hand, controllable sand production may increase wellbore productivity and reduce wellbore completion costs ( Saucier, 1974 ).
1. Introduction. Sand production has been a serious concern for the oil and gas industry for decades. The costs associated with sand production are estimated to run into billions of dollars on an annual basis (Orourke et al., 2004).Sand production refers to the transport of solid particles, in particular sand flakes and individual grains, in oil …
E&P Exchange. Many investigators over the years have researched the causes of sand production and searched for a reliable means to predict it. Sand production prediction is important because of the safety, environmental, and operational concerns involved when produced sand particles fill and plug the wellbore, erode …
Perforated wells in ultra‐deep sandstone reservoirs are characterized by high reservoir temperature, high formation pressure, and high production, and sand production will cause severe safety hazards to these wells.

Sanding happens when there is a weakening of the grain bonding materials [6], resulting to a reduction in the rock's strength or steady degradation [7]. This may be because of mechanical processes or chemical-rock interaction [8], and transport of the grain particles by the reservoir fluid [9]).During well cementation, well drilling, well shut-in and …
