As most producing fields rely on an exclusionary approach to sand management, retrofit of sand separation equipment into existing facilities is a common method of treating unplanned sand production. The retrofit design is an economic decision that balances sand production issues with space, weight, and process constraints.

A lot. The first experiments in the 1940s used around 150 pounds of sand, but now it's around 5 million pounds per well. So, if you are in the Eagle Ford and are looking for a 20/40 mesh and your buddies are all speaking highly of "Antioch Sand" you can expect to spend .056 * 5,000,000 = 280,000 on sand!

Choke Valves are subjected to typical wellhead extreme conditions which can cause erosion, corrosion and other damage. Typically this can include high fluid velocity, slugging, sand production and multiphase of oil, gases and water. Also a Choke Valve has to have a very high turndown capability as it has to cover a wide range of flowrates.

Continued accumulation of the sand in the wellbore will eventually cut the oilproducing rate and may even halt production altogether. When this problem, known as sanding, occurs, a service rig equipped with a sand pump on a wire line is called to the scene. The sand pump is a special tool which removes the sand from the wellbore.
