how to remove feldspars from sand production

Erosion of material (sand production) in an oil wellbore

The erosion equation is. Ve =λ(1−n)cvw, V e = λ ( 1 - n) c v w, where Ve V e is the erosion velocity, vw v w is the pore fluid velocity, c is the transport concentration, n is the porosity, and λ λ is the so-called sand production coefficient. λ λ depends on the equivalent plastic strain ( ¯εpl ε ¯ p l ).
