Sand production is a major problem in the oil and gas industry. Loss of production, sand disposal issues, the need for routine<br>cleanouts, damage to well jewelry, and stuck well accessories are the most common reasons for setbacks caused by sand<br>production. The sand control methods yield the most desirable results when are implemented early in the life of a well before<br>sand production becomes a problem because of the onset of water production or before formation damage occurs as a result<br>of formation disturbances or subsidence. For the wells that start sand production at a later stage, workover with conventional<br>gravel packing is one way to alleviate the problem, but such a costly undertaking is not always economically justifiable.
