Soil Exploration – Purpose, Planning, Investigation and Tests
The nature and extent of soil exploration depends upon the ultimate use to which the results of the investigation will be applied. For example, for structures which transmit heavy load on the soil, the aim of soil exploration is to provide data which will help in the selection of proper types of foundation, its location and design of foundations.
Sand control OilfieldWiki
Sand control methods may be classified as mechanical and chemical. Mechanical methods of sand control prevent sand production by stopping the formation with liners, screens or gravel packs. Larger formation sand grains are stopped, and they in turn stop smaller formation sand grains.

gravel pack Schlumberger Oilfield Glossary
A sandcontrol method used to prevent production of formation sand. In gravel pack operations, a steel screen is placed in the wellbore and the surrounding annulus packed with prepared gravel of a specific size designed to prevent the passage of formation sand. The primary objective is to stabilize the formation while causing minimal impairment to well productivity.
