Production problems - AAPG Wiki

The production of oil or gas from underground reservoirs involves chemical and mechanical processes that affect the wellbore. Many of these processes can eventually cause a problem with the well, resulting either in a decrease in production or in failure of equipment installed downhole or at the surface.

Sand - Wikipedia

Sand is a granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.
