“…The time interval of 3 h of the carrousel scheme is based on experiences of the plant operator, trial and error, and theory (van Beek et al 2009b). At this moment, this time interval of 3 h is also applied on other wellfields sensitive to wellbore clogging.…”

“…The load of particles accumulated on the wellbore during abstraction may be represented as follows (van Beek et al 2009b): where B area,owb is the specific particle accumulation on ‐wellbore (n/m 2 ), Q the abstraction rate of the (submersible) pump (m 3 /h), d the diameter of the wellbore (m), L the length of the well screen (m), c aquifer the background particle concentration in groundwater in the aquifer (n/m 3 ), c wellhead the particle concentration in abstracted groundwater (n/m 3 ), and Δ t the length of abstraction period (h).…”

“…These particle accumulations may dissipate during rest and the particles carried away with the abstracted water after switching on the pump again. Consequently, this type of clogging can be prevented by regular alternation of abstraction and rest (van Beek et al 2009b). This method of well operation has now been used on the wellfield of Tull en ’t Waal (water utility Vitens Midden Nederland) for more than 4 years.…”

Well clogging and productivity decline have been widely observed in oil, gas, and artesian wells producing reservoir fines. The phenomenon has been explained by the lifting, migration, and subsequent plugging of the pores by the fine particles, finally resulting in permeability decrease. This has been observed in numerous core flood tests and field cases. In this work, the new basic equations for the detachment of fine particles, their migration, and size exclusion, causing the rock permeability decline, have been derived. The analytical model, developed for the regime of steady-state production with the gradual accumulation of strained particles, exhibits the linear skin factor growth versus the amount of produced reservoir fines. The modeling data are in good agreement with the well production history. The model allows predicting well productivity decline due to fines production based on short-term production data.

Wells abstracting groundwater are often susceptible to screen slot (chemical) clogging and well bore (mechanical) clogging. Well clogging can cause a decrease of a well—s specific capacity over time and may threaten its reliability. Both types of clogging can be easily diagnosed during operation with the help of entrance resistance—the difference in head between the abstraction well and the observation well in its gravel pack. An increase in entrance resistance over time indicates screen slot clogging. The increasing resistance is caused by accumulation of chemical precipitates in the screen slots and adjacent gravel pack. Well bore clogging, however, does not show an increase in entrance resistance. Both types of clogging can be easily prevented, or at least mitigated, by two opposing methods of well operation: continuous abstraction for wells susceptible to screen slot clogging, and discontinuous abstraction (alternating operation with idle periods) for wells susceptible to well bore clogging.
