well screen with gravel packs

gravel pack - Schlumberger Oilfield Glossary

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.What is Well Screen in a Groundwater Monitoring Well?A well screen helps to keep most of this fine material out of your well water.This lessens the need for filtering the water and keeps the water flowing.Adding a gravel pack around the well screen helps filtrate the water even more than the well screen alone.The gravel pack provides another layer of filtering around the screen.Well Screens and Gravel Packsa,Ground Water 10.1111/j Well Screens and Gravel Packsa Well Screens and Gravel Packsa Blair,A.Hunter 1970-01-01 00:00:00 ABSTRACT The purpose of well screens and gravel packs is to maintain open access within the aquifer ensuring that thorough development of the well is not impeded by sand.Where a well draws on unconsolidated sands and gravels,or other friable materials,the installation of a screen and pack

The purpose of well screens and gravel packs is to maintain open access within the aquifer ensuring that thorough development of the well is not impeded by sand.Where a well draws on unconsolidated sands and gravels,or other friable materials,the installation of a screen and pack is essential.Well Screens and Gravel Packsa - Blair - 1970 The gravel pack should ensure that the completed well operates free of sand; thus the particle size of the pack depends upon the particle size of the aquifer.Gravel pack design should be guided by standard sieve analysis.It is evident from the variety of claims made for well screens and gravel packs that further research is necessary.Well Screens Weatherford InternationalScreen selection can have a far-reaching effect not only on the life of your downhole equipment and tubulars,but also on long-term well productivity and efficiency.From conventional to specialty sand screens such as our shunt-tube designs,our tailor-engineered solutions help you to increase tool longevity and achieve optimal production.
